Bug fixes

  • setPivotMatrix was not setting pivot correctly. This is now fixed. We also introduced a new setPreTransformMatrix to reproduce the sometimes needed behavior of the previous setPivotMatrix function (deltakosh)

  • Fixed WebCam Texture on Firefox and Edge - #3825 (sebavan)
  • Add onLoadObservable on VideoTexture - #3845 (sebavan)
  • beforeRender is now triggered after the camera updated its state - #3873 (RaananW)

Breaking changes

  • Removed the unused PostProcessRenderPass class and extended postProcessingRenderingEffect to support multiple PostProcesses (trevordev)
  • VertexData.merge no longer supports merging of data that do not have the same set of attributes. (bghgary]
  • glTF 2.0 loader now creates a mesh for each primitive instead of merging the primitives together into one mesh. If a mesh only has one primitive, the behavior is the same as before. This change only affects meshes that have multiple primitives. (bghgary]
  • Engine's onCanvasPointerOutObservable will now return a PointerEvent instead of the Engine. (trevordev)
  • Removed public references to default rendering pipeline's internal post process (trevordev)
  • Bone.setScale does not support scaleChildren property anymore. You can use Bone.scale to achieve the same effect (deltakosh)
  • Vector3 & Vector4:
    • MinimizeInPlace has been renamed to minimizeInPlace
    • MaximizeInPlace has been renamed to maximizeInPlace
