Breaking changes

  • When a seven character hex string is passed to Color4.FromHexString, the alpha component will default to 1 instead of defaulting all components (r, g, b, and a) to 0. (BlakeOne)
  • List of breaking changes introduced by our compatibility with WebGPU
  • Use both mesh.visibility and material.alpha values to compute the global alpha value used by the soft transparent shadow rendering code. Formerly was only using mesh.visibility (Popov72)
  • Depth renderer: don't render mesh if infiniteDistance = true or if material.disableDepthWrite = true (Popov72)
  • Mesh.createInstance no longer make a unique Geometry for the Mesh so updating one Geometry can affect more meshes than before. Use Mesh.makeUniqueGeometry for old behaviour. (breakin)
  • Ammo.js needs to be initialized before creating the plugin with await Ammo(); since Ammo introduced an async init in their library. (sebavan)
  • Recast.js needs to be initialized before creating the plugin with await Recast(); since Recast introduced an async init in their library. (CedricGuillemet)
  • Custom shaders using instancing must use instanceColor instead of color so mesh vertex colors can be used with instancing. (CedricGuillemet)
  • Fixed spelling of EventState.initialize (seritools)
  • SkeletonViewer is now enabled by default (Deltakosh)
  • BindEyePosition has been moved from Material to Scene to avoid a circular dependency problem and is now a non-static method (bindEyePosition) (Popov72)
  • The depth renderer was not generating correct values for orthographic cameras when storeNonLinearDepth = false (Popov72)
  • dataBuffer.ts has been moved from Meshes/ to Buffers/ (Popov72)
  • By default, the glTF loader now uses sRGB buffers for gamma encoded textures (when supported by the GPU), which is more accurate than using regular buffers. However, it can lead to small visual differences. You can disable usage of sRGB buffers by setting glTFFileLoader.useSRGBBuffers to false (Popov72)
  • 4th (isAnimationSheetEnabled) and 5th (customEffect) parameters of GPUParticleSystem constructor have been inverted to match ParticleSystem constructor (Popov72)
  • PBRSubSurfaceConfiguration.useGltfStyleThicknessTexture has been renamed to PBRSubSurfaceConfiguration.useGltfStyleTextures (Popov72)
  • Properties in IWebXRHandTrackingOptions related to hand and joint meshes have been moved into jointMeshes and handMeshes members, respectively (rgerd)
  • IWebXRHandTrackingOptions.jointMeshes.onHandJointMeshGenerated() provides a hand instead of a controllerId in the parameters, since the tracked joint meshes are pre-generated (rgerd)
  • You should now access joint meshes from WebXRHand through the getJointMesh() function (rgerd)
  • Rework of the inner working of render targets. Those are mostly internal changes. From the end user standpoint, the most visible change is that the PostProcess class is now dealing with RenderTargetWrapper instead of InternalTexture objects. So, if you are directly updating the inputTexture property with a render target texture that you previously rendered, you will need to pass a RenderTargetWrapper instead of an InternalTexture: you will get it by doing rtt.renderTarget, where rtt is the instance of your RenderTargetTexture. (Popov72)
  • ShaderMaterial is now storing the effect on submeshes by default. It may be a breaking change in some special cases where one creates a ShaderMaterial not to be used as the material property of a mesh but instead to handle it "by hand" by calling ShaderMaterial.isReady / ShaderMaterial.bind directly. If you are doing that, you may want to pass false as the 5th parameter of the ShaderMaterial constructor to disable storing the effect on submeshes.
  • The glTFLoader.rootBabylonMesh getter now has a nullable return type (glTF files without mesh data) (simonihmig)
  • When updating the m array of the Matrix class directly, you must call markAsUpdated() explicitly or the matrix changes may not take effect (Popov72, Deltakosh, bghgary, Sebavan)
  • Loading glTF assets with skins now places skinned meshes as siblings of the corresponding skeleton root nodes instead of using skeleton.overrideMesh. (bghgary)
  • The overrideMesh of the Skeleton class has been removed. (bghgary)
  • Cloning a mesh now assigns the skeleton property to the source skeleton. (bghgary)
  • Cloning and creating instances of a mesh now refreshes the bounding box applying skins and morph targets. (bghgary)
  • KeyboardInfoPre.skipOnPointerObservable is now correctly renamed to KeyboardInfoPre.skipOnKeyboardObservable. (bghgary)
  • GLTF Animations are loaded at 60 FPS by default, instead of the previous 1 FPS. (carolhmj). If you'd like to keep your existing animation ranges, you can use this workaround:
BABYLON.SceneLoader.OnPluginActivatedObservable.add(function(plugin) {
  if (plugin.name === "gltf") {
    plugin.targetFps = 1;
  }
});
  • currentState and previousState have been removed from use in onInputChangedObservable in the DeviceSourceManager (PolygonalSun)
  • PointerInput movement enums are no longer being used in any movement event handling in the DeviceInputSystem and InputManager (PolygonalSun)
  • Shadow generators now use the Material.alphaCutOff value instead of a hard-coded 0.4 value. (Popov72)
