# Needle Engine Changelog

[`@needle-tools/engine`](https://www.npmjs.com/package/@needle-tools/engine) — Latest: **5.0.2**

## 5.0.2 - 2026-04-03
- Updated `@needle-tools/materialx` to 1.6.0:
  - UV coordinate convention handling (glTF ↔ OpenGL) — fixes UV-dependent effects like displacement and procedural noise in the browser
  - Material-level ambient occlusion for `gltf_pbr` materials per the glTF specification
  - Visual graph editor for interactive MaterialX authoring
- Fix: Light intensity in scaled AR session

## 5.0.0 - 2026-03-27
- **NEW**: Compression support for EXR skybox and environment textures (powered by Needle's [FastHDR](<https://engine.needle.tools/docs/explanation/fasthdr.html>)):  
  - 10x faster than EXR
  - 95% less GPU memory
  - Zero framedrops
- **NEW**: Support for Vite 8, now powered by Rolldown (Rust) for extremely fast bundling
- **NEW**: MaterialX *Lights and Magic* update:
  - Lights and shadow suppport: point lights, spot lights, directional lights
  - Displacement: full support for offset and vector displacement
  - Transparency Modes: auto-detection and support for opaque, transparent, and masked material rendering modes
  - See 
- Change: OrbitControls now uses `lookAtTarget` and `lockLookAtTarget` instead of a LookAtConstraint component. The LookAtConstraint component has been deprecated.
- Change: EventList `addEventListener` now returns a method that can be called to remove the callback function again: `const remove = myEventList.addEventListener(() => { ... })`
- Change: Rapier Physics colliders will now just be disabled instead of removed from the physics world when a Collider component becomes inactive.
- Change: Postprocessing now has an `adaptiveResolution` option (default true) which can automatically scale down resolution slightly for Retina or high pixel density screens if performance drops (See the `Volume` component for more information)
- Improved: Networking types (Typescript)
- Improved: Dependencies chunking for faster loading and improved LCP score(Largest Contentful Paint)
- Fix: NextJS support

## 4.16.4 - 2026-03-18

## 4.16.1 - 2026-03-09
- Fix: Regression causing error in react

## 4.16.0 - 2026-03-05
- **NEW**: `makeFilesLocal` build option overhauled — builds can now be fully self-contained and work offline. The plugin downloads external CDN assets at build time and bundles them locally. This is essential for playable ads, app stores that require single-origin or self-contained bundles, offline-capable PWAs, and restricted hosting environments. Supports auto-detection of used features, per-feature opt-in/opt-out, and platform presets. Covers Draco decoders, KTX2 transcoders, MaterialX, WebXR input profiles, skybox/environment textures, Google Fonts, third-party scripts, and more.
  Example in `vite.config.js`:
  ```js
  needlePlugin({
    makeFilesLocal: "auto" // auto-detect and download only what your project uses
  })
  // or with fine-grained control:
  needlePlugin({
    makeFilesLocal: {
      enabled: true,
      features: ["draco", "ktx2", "fonts"],
      excludeFeatures: ["xr"]
    }
  })
  ```

Powered by Needle Go AppClip, combining Apple's excellent AR tracking with standards-compliant WebXR. Try it at [appclip.needle.tools](https://appclip.needle.tools)
- **NEW:** Intellisense support for the `<needle-engine>` web component and its attributes, both in HTML and in code. The `custom-elements.json` allows for VSCode intellisense support, while `HTMLElementTagNameMap` and `get/setAttribute` overloads bring code completion and documentation.
- Add: exposed `createCollider` API for the Rapier physics engine
- Add: `beforeLODExport` callback for USDZ export. This allows overriding which LOD level gets exported per object.
- Add: `?spector=#frame` URL parameter to enable a Spector.js capture on the specified frame number after page load. Make sure to install the [Spector.js browser extension](<https://chromewebstore.google.com/detail/spectorjs/denbgaamihkadbghdceggmchnflmhpmk?pli=1>). You can optionally specify a frame number for capturing: `?spector=15`.
- Add: auto-registration of custom elements for easier discovery of available web components in Needle Engine. You can disable this feature by setting `noCustomElementData` to false in vite config. To manually register custom elements data, add it to your workspace or `.vscode/settings.json` via the `html.customData` setting.
- Add: Support for rotation and scaling in DropListener component

- Improve JSDoc documentation

## 4.11.3 - 2025-10-21
- Fix: See-Through with MeshPhysicalMaterial

## 4.11.2 - 2025-10-20
- Change: Animation component disable `randomStartTime`
- Change: Vite build build pipeline plugin increased default max wait time to 60 seconds.  
  This time is now exposed via `needlePlugins` user config, e.g. to increase it to 5 minutes write `needlePlugins(command, needleConfig, { buildPipeline: { maxWaitDuration: 300_000 } })` in your `vite.config.js`.

## 4.11.1 - 2025-10-16
- Fix: WebXR / VR issue where trying to access missing geometry during raycasting caused errors
- Change: ScrollFollow now only applies when scroll has changed. It also immediately jumps to the target position on the first update instead of interpolating (avoiding interpolation through long timeline animations).
- Change: SplineWalker now has an option to disable LookAt. It also received a `pullStrength` property which controls how tightly the object moves along the spline. 
- Improved: OrbitControls and ViewBox interaction 

## 4.11.0 - 2025-10-15
- **NEW**: SeeThrough component. With this component you can easily fade-out objects between the camera and a reference point in the scene. See the [See-Through sample](<https://see-through-walls-z23hmxbz1kjfjn.needle.run/>) to see it in action
- **NEW**: [Droplistener sample](<https://engine.needle.tools/samples/droplistener/>)
- Add: CursorFollow option to follow cursor on the full page, even when a user moves their mouse outside of the `<needle-engine>` element.
- Add: CursorFollow `snapToSurface` option to automatically snap the object to the surface below the cursor.
- Add: Object3D `raycastAllowed` property to disable raycasting on specific objects (e.g. for performance reasons or to ignore invisible helper objects)  
- Add: OrbitControls `targetBounds` property which can be used to constrain the OrbitControls target within a defined area in the scene. A Object3D can be assigned to the property. The position and scale of this object will be used.
- Add: *Experimental* - Vite plugin to generate `needle-app.js` which encapsulates the whole website into a single web component. The `needle-app.js` file will be emitted next to index.html and can be used to directly embed the website and 3D assets into another website by importing `<url>/needle-app.js` and then using the `<needle-app></needle-app>` web component.
- Add: Object3D `contains(otherObject: Object3D)` method to check if an object is a child of another object in the scene graph
- Fix: three nodes update camera for TSL
- Fix: Renderer lightmaps are now updating `sharedMaterials`
- Fix: `Gizmos.DrawWireMesh` matrix
- Fix: Image UI color was sometimes not correctly calculated for Button color states when used with the CanvasGroup component
- Fix: ScrollMarker issue
- Improved JSDoc documentation

## 4.10.4 - 2025-10-08
- Update: three-animation-pointer dependency to 1.0.4 to support KHR_node_visibility extension
- Documentation improvements

## 4.10.3 - 2025-10-06
### Needle Engine
- Add: [`ScrollFollow`](<https://engine.needle.tools/docs/api/ScrollFollow>) timeline markers can now be defined in HTML only and don't require markers to be present in the Timeline anymore. This means any timeline animation can now be mapped to HTML content by annotating the HTML elements. 
  For example `<div data-timeline-marker="2.5">` will define that the timeline should reach the time 2.5 seconds when this element becomes visible in the viewport. The [bike-scroll-follow example on Github](<https://github.com/needle-engine/needle-engine-bike-scrollytelling/tree/main>) will be updated to use this new feature soon ([example index.html](<https://github.com/needle-engine/needle-engine-bike-scrollytelling/blob/main/Scroll%20Bike%20Website/index.html>)).

## 4.10.1 - 2025-09-30
- Change: ViewBox `referenceFieldOfView` can now set to `-1` to automatically take the camera's field of view at runtime
- Fix: ViewBox evaluation order is now hierarchy-independent (Previously OrbitControls panning might be applied after ViewBox calculations if the ViewBox component was on a parent object)

## 4.10.0 - 2025-09-29
- **NEW**: [**Scrollytelling Bike Example**](https://scrollytelling-bike-z23hmxb2gnu5a.needle.run/) – This example uses ViewBox, FocusRect and ScrollFollow to create a scrollytelling experience. All project files are [available on Github](<https://github.com/needle-engine/needle-engine-bike-scrollytelling>).
- **NEW**: HoverAnimation component. Use this component to get a scale hover animation of an object when the cursor is hovering over the object or one of it's children.
- **NEW**: ViewBox component. Use this component to automatically perfectly fit your 3D scene into the camera view. Try the Scrollytelling Example to see it in action, test the [example on Stackblitz](<https://stackblitz.com/edit/needle-engine-view-box-example?file=src%2Fmain.ts>) or see the [ViewBox documentation](<https://engine.needle.tools/docs/api/ViewBox>) for details.
- Add: `fitCamera` function
- Add: `<needle-engine poster>` attribute. It works with an URL to an image that should be shown as a poster image. If no URL is assigned then the poster that is automatically generated during the first frame will be used.
- Add: `<needle-engine focus-rect="<html_selector">` attribute. Assign a HTML selector to the attribute to use a specific HTML element on screen offset the 3D camera center to the center of the HTML element. (The same can be done programmatically using `ctx.setCameraFocusRect(<html_element|DOMRect>)`)
- Add: Timeline [ScrollMarker](<https://engine.needle.tools/docs/api/ScrollMarkerModel>) for Unity and Blender timeline animations to control timing based on HTML visibility.  
- Fix: Renderer `material` accessing error when component was not yet initialized 
- Fix: Poster screenshot glitch during the first frame (development only)
- Fix: HTC Vive Focus 3 controller movement ([forum post](<https://forum.needle.tools/t/movement-via-controller-in-vr-with-htc-vive-focus-3/2718>))
- Change: Loading display does not show Needle logo anymore by default
- Change: Use fallback raycast method for lowpoly meshes while the faster mesh BVH is being generated

## 4.9.3 - 2025-09-15
- Fix: SpriteRenderer index issue when animated where animation precision issue was causing the wrong sprite to be selected ([issue](<https://forum.needle.tools/t/switching-sprite-images-via-timeline-causes-ghosting-glitches-when-exported/2709>))
- Fix: Scaling scene in AR with multitouch causing camera projection issue for a frame ([issue](<https://forum.needle.tools/t/3d-assets-warping-on-rotation-in-ar>))

## 4.9.1 - 2025-09-11
- Update [ScrollFollow component](<https://engine.needle.tools/docs/api/ScrollFollow>) documentation
- Update Renderer `sharedMaterial` typescript type

## 4.9.0 - 2025-09-08
- **NEW**: [**Scrollytelling Example**](<https://scrollytelling-2-z23hmxby7c6x.needle.run/>)
- **NEW**: Spline support with SplineContainer and SplineWalker components
  - SplineContainer: Holds the spline data. Use `addKnot` and `removeKnot` to modify the spline and `getPointAt(t01:number)` to get a point on the spline curve. Splines currently only support cubic interpolation.  
  - SplineWalker: Component for moving objects along a spline. It can automatically move along the spline or be controlled by animations or other components by setting the `position01` property.
- **NEW**: [Attractor component](<https://engine.needle.tools/docs/api/Attractor>) – Add Rigidbodies to the list to attract physical objects towards a point in space (or apply repulsion).
- **NEW**: [CursorFollow component](<https://engine.needle.tools/docs/api/CursorFollow>) – Does what it says! Add the component to an object to make it follow your cursor (or touch) on screen.
- **NEW**: [ScrollFollow component](<https://engine.needle.tools/docs/api/ScrollFollow>) – Use browser scroll to influence animation, audio, light... in your scene.  
- Add: WebXRImageTracking methods for `setPrimaryImage` and `addImage` to simplify image tracking changes at runtime.
- Add: Object3D `worldForward` can now be set (e.g. `myObject.worldForward = new Vector3(0,0,1)`)
- Fix: [XR] Issue where NeedleXRSession would invoke controller-added callback twice
- Fix: [XR] Issue where invalid value in XRControllerMovement would break rendering when using hand tracking
- Fix: [XR] NeedleXRController getButton for xr-standard-trigger and getStick("primary")
- Fix: Capsule collider height
- Fix: Issue where disposing object resources would cause errors in three.js

## 4.8.9 - 2025-09-05
- Add: OrbitControls `fitCamera` has now additional options for `fitDirection`, `cameraOffset`, `relativeCameraOffset`, `targetOffset` and `relativeTargetOffset` giving more fine-grained control over the final camera view where necessary ([Stackblitz](<https://stackblitz.com/edit/needle-engine-fit-camera-options?file=src%2Fscripts%2FPanelsAndText.ts,index.html,src%2Fmain.ts>)).
- Add: ContactShadows properties to `fitShadows` and static `ContactShadows.auto()` for more fine-grained control over which objects to fit the shadow to or to apply slight offsets to the shadow plane
- Add: NestedGltf component `loaded` event property
- Fix: OrbitControls should not override the camera FOV
- Fix: Updating the `scene.background` when setting both &lt;needle-engine> `background-color` and `background-image` or switching between one or the other
- Fix: When setting `<needle-engine environment-image="url">` the assigned image should be respected by the engine and loaded glTF files (even if they bring their own skybox and environment images)
- Fix: Issue with `<needle-engine autoplay>` animation speed and when using the AnimationUtils.autoplay feature where animations would play faster than expected
- Fix: Minor fixes in Vite plugins
- Change: ReflectionProbes are not applied on Objects that use lightmapping

## 4.8.8 - 2025-08-29
- Fix: iOS AR image tracking bug where having multiple `WebXRImageTracking` components in the scene cause unexpected behaviour or invalid USDZ files 
- Fix: DropListener `loadFromURL` now returns the promise to make awaiting the loaded asset much easier
- Fix: Issue where `<needle-engine autoplay>` would play animations faster than expected
- Change: OrbitControls with locked target constraint is now updating the constraint position when calling e.g. `setTargetPosition`
- Add: `setCameraFocusRect` method on Needle Context for easier responsive layouting.   
  With this you can e.g. overlay the webgl scene with HTML elements and pass in a div element for keeping important elements visible.  
  [Example 1 Website](<https://responsive-layout-z23hmxb22no6t.needle.run/>) | [Code on Stackblitz](<https://stackblitz.com/edit/needle-engine-camera-focus-rect?file=src%2Fsidebar.ts,index.html,src%2Fmain.ts>)

  [![](https://cdn.needle.tools/static/images/changelog/4.8.8-focus-2-thumbnail.jpg?)](<https://responsive-layout-click-example-z23hmxbzuyk6y.needle.run/>)

## 4.8.7 - 2025-08-27
- Add: New [@needle-tools/three-animation-pointer](<https://www.npmjs.com/package/@needle-tools/three-animation-pointer>) package
- Add: `loadPMREM(<url>)` function 

## 4.8.6 - 2025-08-20
- Bump three dependency to fix issue caused by KTX2Exporter

## 4.8.5 - 2025-08-20
- Add: Much faster loading for skyboxes and environment maps when using presets. E.g. `<needle-engine environment-image="studio"></needle-engine>`. Supported values are `studio`, `blurred-skybox`, `quicklook`, `quicklook-ar`
- Change: TransformControls now also enable `fastMode` on the SyncedTransform component 
- Change: The mobile javascript console now needs to be explictly enabled using the `?console` flag. This change has been made to improve the local development experience. Previously the javascript console would be initialized in local development environments but stay invisible until e.g. an error would be detected. This did sometimes cause performance issues when very large objects would be logged in development

## 4.8.4 - 2025-08-18
- Update `@needle-tools/gltf-progressive` dependency which adds a `waitForFirstCapture` bool option to `awaitLoading(<opts>)`. With this you can call `manager.awaitLoading({waitForFirstCapture:true})` to get a promise that does not resolve until the next requested LOD levels have finished to load.   
  [**Here**](<https://lods-loading-overlay-z23hmxbz29h8vr.needle.run/>) is an example deployed to Needle Cloud + [here](<https://stackblitz.com/edit/needle-engine-wait-for-lods?file=src%2Fmain.ts>) is a example on Stackblitz which makes use of this feature to add a custom loading overlay.
- Fix: When using Needle Engine in Gemini Editor the webrtc dependency caused issues due to Gemini making `getUserMedia` read-only.  
  [**Example React Shopping App**](<https://reactshoppingcart-z23hmxbzcfkmf.needle.run/>) built by Gemini with Needle Engine ([Code on Stackblitz](<https://stackblitz.com/edit/needle-react-shopping-cart-2?file=src%2FApp.tsx,index.html,src%2Fmain.tsx>))
- Fix: When using pre-bundled Needle Engine (e.g. from jsdelivr) the mesh-bvh worker path was not correctly resolved
- Change: `<needle-engine>` CSS z-index setting where the `<needle-menu>` element would be rendered above elements outside the `<needle-engine>` component. This would cause issues where e.g. a sidebar should overlay the page. 
- Change: Reduce default z-index for Needle loading logo

## 4.8.3 - 2025-08-18
- Change: Clamp devicePixelRatio to `2` by default. This can be overriden by setting the Needle Engine Context's `devicePixelRatio` to e.g. `window.devicePixelRatio`
- Update `@needle-tools/gltf-progressive` dependency to expose `overrideLodLevel`. This can be used to override which LOD level will be loaded instead of calculating the LOD level based on screen coverage:  
  For example `context.lodsManager.manager!.overrideLodLevel = 0;` will always load the highest quality mesh + texture

## 4.8.1 - 2025-08-14
- Fix: SceneSwitcher dispose of background and environment texture causing lighting issues when `useSceneLight` is disabled in SceneSwitcher component
- Fix: Detection of model/gltf+json by file header

## 4.8.0 - 2025-08-12
- Add: `Gizmos.DrawWireBox` now takes an optional `rotation` parameter
- Add: Physics `boxOverlap` function
- Fix: Vite plugin improvements
- Fix: Issue where re-applying Postprocessing effects with custom devicePixelRatio did falsely reset devicePixelRatio 
- Update `@needle-tools/gltf-progressive` to version 3.2.0 with experimental javascript worker support. It can currently only be enabled by adding the URL query parameter `?gltf-progressive-worker` 

## 4.7.4 - 2025-08-07
- Update `@needle-tools/gltf-progressive` to version 3.1.1

## 4.7.3 - 2025-08-06
- Add: OrbitControls `rotateUp(<radians>)` function
- Add: OrbitControls support for setting `targetElement` (e.g. `orbitControls.targetElement = myNewHtmlElement;`)
- Fix: RemoteSkybox loading relative URIs like "folder/image.exr", catch errors in loadAsync
- Update gltf-progressive dependency with improved performance when using skinned meshes and a concurrent LOD request limit (default: 100 concurrent requests)

## 4.7.2 - 2025-08-04
- Add: `loading-blur` attribute to `<needle-engine>` web component. With this attribute the 3D scene will be blurred using CSS during loading of initial LOD level.   
This feature can be used to hide initial low-resolution textures and meshes while already getting an interactive preview visible in the browser (e.g. when displaying high quality product models where the 3D model download should be fast and not block the website but low-res assets should never be visible to the user)  
Currently `loading-blur` is disabled by default but can simply be enabled:   
   - Enable default blur: `<needle-engine loading-blur></needle-engine>`   
   - Or to control the blur amount a pixel value can be passed in `<needle-engine loading-blur="30px">`   
- Add: You can now await LOD loading at any time by calling `context.lodsManager.manager?.awaitLoading()`. The method accepts an optional options argument and returns a promise that will resolve when all requested LOD level during the next frame have completed loading. Please review the jsdoc code documentation for details.
- Add: The `physics.raycast` options now accept an optional argument (`allowSlowRaycastFallback`) which controls wether or not the traditional three.js `raycast` method is allowed. If this parameter is set to false then only objects with a finished bvh mesh will be used for raycasting to ensure raycasts are always fast and never fallback to the slow route. This is especially important for relative frequent raycasts like mouse-movements or camera-target updates where it's not crucial if objects are ignored for a few frames. Needle Engine does automatically calculate mesh BVHs for all meshes in the scene on a worker at the first time they're discovered to ensure optimal performance. 
- Add: OrbitControls methods for `pan(<delta-x>, <delta-y>)`, `zoomIn(<scale>)` and `rotateLeft<angleInRadians>`. These methods can be used to control camera movement from code or via custom key-bindings.
- Update gltf-progressive which adds support awaiting LOD level + improved LOD level calculations where meshes have multiple primitives/submeshes.
- Fix: `useKeys` in OrbitControls - it requires `tabindex` on the `<needle-engine>` web component to receive keyboard events 
- Fix: Clamp of tonemapping exposure in AgX
- Fix: Issue in Vite plugin with logging of very large objects

## 4.7.1 - 2025-07-31
- Add: LODsManager parameter `skinnedMeshAutoUpdateBoundsInterval`
- Fix: Issue where model fetch with query parameters was constructing a wrong URL

## 4.7.0 - 2025-07-28

   ```ts
   import { NeedleEngineModelLoader } from "@needle-tools/engine";
   import { STLLoader } from "three/examples/jsm/loaders/STLLoader.js";

   // Register a callback for determining our custom loader mimetype
   NeedleEngineModelLoader.onDetermineModelMimetype(args => {
    // check if the mimetype is already provided by the server
    if (args.contentType === "model/stl") {
        return "model/stl";
    }
    // use URL extension if available
    if (args.url.endsWith(".stl")) {
        return "model/stl";
    }
    // check if first few bytes start with "solid"
    // this is a very naive check, but it works for most cases
    if(args.bytes[0] === 0x73 && args.bytes[1] === 0x74 && args.bytes[2] === 0x6c) {
        return "model/stl";
    }
    return null;
   });

   // Register a callback for creating our custom loader
   NeedleEngineModelLoader.onCreateCustomModelLoader(args => {
    if (args.mimetype === "model/stl") {
        const stlLoader = new STLLoader();
        return stlLoader;
    }

- Change: Needle Engine loading view is now transparent by default. The `loading-background` attribute can be used to add custom styling like `<needle-engine loading-background="#000" />`. Alternatively the `<needle-engine>` web component or background can be styled.
- Removed: Web component attributes: `loading-background-color`, `loading-style`, `loading-text-color`
- Fix: Vite HMR (Hot Module Replacement) working nicely with browser breakpoints and debugging

- Add: License validation for webpack (nextjs) via access token or teamid. The `needleNext` plugin does now handle the license for passed in team or access tokens.   
  For example the `next.config.js` can be modified like so `... }, { modules: { webpack }, license: {team: "needle"} })` to pass in the name of a team (or a Needle Cloud access token).
- Change: License checks will now read the `NEEDLE_CLOUD_TOKEN` environment variable if no access token is provided.

- Fix: Vite `manualChunks` should not be declared if `rollupOutput.inlineDynamicImports` is set to true

## 4.4.0 - 2025-04-17
**Added**
- Add: The needle-engine web-component `contactshadows` attribute now allows you to specify a factor for controlling the darkness/lightness. E.g. `<needle-engine contactshadows="1">` will make the shadows appear darker vs. `<needle-engine contactshadows=".2">` will make the contact shadow appear lighter.
- Add: The needle-engine web-component does now support transparency for `background-color`. For example: `rgba(255, 255, 100, .5)` or `#ffdddd99` or `transparent` are valid values: `<needle-engine background-color="rgba(255, 255, 100, .5)" />`
- Add: `ObjectUtils.createPrimitive()` now supports scale as array   
    e.g. `ObjectUtils.createPrimitive("Cube", { scale: [1, .25, 1] } );`
- Add: Input `getGamepad(<index>)` function to query a connected gamepad. Example: `this.context.input.getGamepad()`
- Add: `lookAtScreenPoint()` function which allows 3D object to look at points in 2D screen coordinates (e.g. your mouse position).    
    **Example Component that makes the object look at the mouse**
    ```ts
    import { Behaviour, lookAtScreenPoint } from "@needle-tools/engine";

    export class LookAtMouse extends Behaviour {
      update() {
        lookAtScreenPoint(this.gameObject, this.context.input.mousePosition, this.context.mainCamera);
      }
    }
    ```
- Add: Default environment lighting. If you don't configure any environment-image needle engine will now create a default scene to light your objects. Previously the scene was just black when the loaded model didn't contain any lighting information.
- Add: SyncedTransform does now also sync scale changes
- Add: SyncedTransform `freeOwnership()` method
- Add: ReflectionProbe bounding box intersection check to automatically apply reflections to object's in a specific area (handled by the Renderer component)
- Add: `devicePixelRatio` option on Needle Context. This option controls the window.devicePixelRatio set on the renderer by Needle Engine (default `auto`). It can be set to `manual` to disable this behaviour or a custom number which will then be set on the renderer or composer.

**Fixed**
- Fix: Implicit camera did not automatically set to skybox when using `background-image`. E.g. `&lt;needle-engine background-image="&lt;url>"> 
- Fix: Tonemapping falsely set tonemappingEsposure to undefined causing a black screen
- Fix: `background-color` attribute was not always applied. E.g. `<needle-engine background-color="#ff3333">`

- Fix: Vite improve license checks in CI environments (e.g. when running via a Github Action).
- Fix: Vite plugins for running in CI environment
- Fix: Vite `manualChunks` are not defined when `preserveModules` is set to true

**Changed**
- Change: License check aborts now faster instead of retrying when connection is actively refused
- Change: OrbitControls `autoTarget` does now automatically update the look at target after panning and not when rotating the camera (previously the target would be updated after any input but this resultet in undesireable behaviour when rotating around objects)
- Change: When no background-color is defined by either the loaded scene or by a `background-color` attribute then the default scene background color respects the user's accessibility setting for `prefer-dark` or `prefer-light`. This means that the background color will be set to a default light or dark value.
- Change: Scene background color or image set on `<needle-engine>` are not overridden anymore by the camera component.
- Change: Hide Needle logo automatically when using Needle Engine with a license

## 4.4.0-beta.9 - 2025-04-07

## 4.3.2 - 2025-03-20
#### Added
- Documentation for `Gizmos` API
- `this.context.time.fps` returning the FPS for the current frame (for a more stable FPS value `smoothedFps` can be used)

#### Removed
- Vite license plugin check does not support Node 16 anymore

#### Changes
- Improve Vite preload link injection into HTML head
- The PostprocessingManager component does now expose a `multisampling` property which is set to `"auto"` by default. By setting `multisampling` to a number it will force postprocessing to the configured samples.
- Downloading of `<needle-engine>` attributes for `skybox-image` and `environment-image` does now start earlier. Previously it would only start loading the HDRi or EXR images after the root glTF file was finished loading. Now it will start downloading earlier which improves the time until the scene is ready to be displayed.

#### Fixed
- Vite dependency-watcher plugin warning
- Vite license check plugin is now using the latest Needle CLI version
- Browser cache busting issue related to loading the root scene where range requests (e.g. when download urls without a file extension). This caused Chrome to remove files from the disc cache causing a re-download
- Three.js core postprocessing effects support
- Loading glTF files without any components (e.g. when directly downloaded from Sketchfab) was causing Needle Engine to falsely keep a reference to the loaded glTF structure. 
- Instancing issue where instancing did sometimes renderer wrong geometry when many objects where removed and added again and multiple different geometries were batched together. This was caused by a bug in the internal bucketing mechanism and has now been removed since it's not necessary anymore.

## 4.3.2-beta.5 - 2025-03-20
- Change: Improve Vite preload link injection into HTML head
- Fix: Vite dependency-watcher plugin warning

## 4.3.2-beta.4 - 2025-03-19
- Fix: Start loading earlier for `skybox-image` and `environment-image` when configured in `<needle-engine>` web component. Previously it would only start loading the HDRi or EXR images after the root glTF file was finished loading. Now it will start downloading earlier which improves the time until the scene is ready to be displayed.
- Fix: Update vite license check using the latest CLI version
- Fix: Issue related to loading the root scene where range requests (e.g. when download urls without a file extension) caused Chrome to remove previously full downloads to be removed from disc cache

## 4.3.2-beta - 2025-03-14
- Add: `this.context.time.fps` returning the FPS for the current frame (for a more stable FPS value `smoothedFps` can be used)
- Change: The PostprocessingManager component does now expose a `multisampling` property which is set to `"auto"` by default. By setting `multisampling` to a number it will force postprocessing to the configured samples.
- Fix: Issue where instancing with multiple different geometries being batched together did sometimes be cause wrong rendering when many objects where removed and added again. This was caused by a bug in the internal bucketing mechanism which is not necessary anymore with the new BatchedMesh version.

## 4.3.1 - 2025-03-14
- Add: Expose lifecylcle hooks in `Needle` global scope for usage in commonjs or without a bundler. For example this allows to subscribe to the update event with `Needle.onUpdate(ctx => console.log(ctx.time.time))`.
- Fix: OrbitControls micro-movement after a pointer event was already used. For example previously when using DragControls and starting to drag an object the camera would still move slightly before stopping during drag. This is not the case anymore now and the camera does not move anymore during interaction with other objects.
- Fix: Canvas UI render settings not being applied in one rare case causing a worldspace image not being set to double sided rendering.

## 4.1.0-beta.5 - 2025-02-04
- Fix: Physics issue with mesh colliders where colliders were sometimes created with the wrong size depending on the users network speed. This was due to the change of lazily loading the physics engine in Needle Engine 4.
- Fix: Add workaround for a regression in the particle system where PBR materials would sometimes render with a wrong texture. [Issue](https://github.com/Alchemist0823/three.quarks/issues/101)

## 4.1.0-beta.2 - 2025-01-29
- Fix: VideoPlayer screenspace mode colorspace 
- Fix: XRRig `setAsActiveRig()` now ensures the given rig has the highest priority. Previously it was possibly immediately overidden again if another XRRig with a higher priority was active in the scene.
- Change: SpatialTrigger EventList events are now invoked without additional parameters. They did previously take a reference to the SpatialTriggerReceiver and active SpatialTrigger. If this information is important the SpatialTriggerReceiver can be saved when subscribing to the event and the trigger can be accessed using the `triggerReceiver.currentIntersected` array.
- Change: TransformGizmo now exposes the underlying three.js TransformGizmo via a new `control` property.
- Change: GroundProjection now uses the `scene.background` instead of `scene.environment`

## 4.1.0-beta.1 - 2025-01-29
- Fix: ParticleSystem custom behaviours
- Fix: OrbitControls not keeping the initial look direction if `autoTarget` was off

- Change: Much improved initial loading speed making Needle Engine websites load up to 1000 ms faster.  
  Improved Needle Engine website lighthouse scores for all Vite based projects.   
  Improved bundle chunking and loading for better lighthouse scores.    
  Core bundles and entrypoint glTF files are not loaded as soon as the web document is ready.
- Change: Needle Engine does now lazily import dependencies for `rapier` and `postprocessing` to reduce download and startup size.   
  This means that projects that don't use any collider or rigidbody components will not load the physics and postprocessing modules. Modules can be loaded at any time once they're need by e.g. components in the scene.

## 4.1.0-alpha.11 - 2025-01-17
- Remove: legacy Flycontrols component

- Fix: Issue where raycasting was not using acceleration structures and instead falling back to slow raycasting. This release greatly improves raycasting performance

## 4.1.0-alpha - 2025-01-08
- Add: Screenshot support for AR:   
  To use you need to request the `camera-access` XR feature when starting a new XR session.

## 2.65.0-pre - 2023-03-09
- Add: runtime checks for recursive loading to prevent it from breaking
- Change: internal duplicate active state on `Object3D` has been removed, instead `visible` is used. This was previously a workaround for the `Renderer` setting the visible state when being enabled or disabled but this has been changed in a previous version and it now only sets a flag in the object's Layers instead (which allows for a single object in the hierarchy to not being rendered by setting `Renderer.enabled = false` while objects in the child hierarchy stay visible) 
- Change: `<needle-engine>` src attribute can now also take an array of glbs to load. This simplifies codegen done by exporters and also prevents errors due to bundler optimizations as well as being easier to understand.

- Add: `Physics.enabled` property for disabling physics updates. This also prevents any collider shapes to be created
- Add: `this.gameObject.transform` property to ease getting started for devs coming from Unity. This property is merely a forward to `this.gameObject` and shouldnt really be used. The property description contains information and a [link to the docs](https://fwd.needle.tools/needle-engine/docs/transform) with further information.
- Fix: instanced materials using progressive loading are now correctly updated
- Fix: Timeline animation tracks now disable the `Animator`. This fixes cases where two animations were played at the same time. When the PlayableDirector is paused or stopped the animator state is reset
