Unity released another patch, 5.4.0p3. Once again composed primarily of bug fixes. The release notes:
- Graphics: GPU Instancing: It is no longer an error to use instanced shaders on renderers that don't support instancing (SkinnedMeshRenderer, SpriteRenderer, etc.)
- Grpahics: GPU Instancing: For statically batched MeshRenderers, using instanced shader now will not break static batching. If you want renderers to be instancing batched, please consider disable static batching flag (816786).
- VR: Oculus GearVR version updated to 1.7.1.
- (820203) - Animation: Fixed a crash in Animation::CreateAnimatorGenericBindings when attempting to use AnimationMixerPlayable on start of a game object.
- (822897) - Animation: Fixed additive layer using disabled "Resample Animation" blended with layers that have it enabled.
- (816567) - Editor: Fixed a bug that launching Editor window will exit after signed on windows.
- (716213) - Editor: Fixed occasional freeze when profiling over network and connection is lost.
- (771779) - Editor: Fixed crash caused by leading and/or trailing slahes in MenuItem names.
- (798702, 810632) - Graphics: Fixed a couple of bugs in the CPU mipmap generation (2D & 3D) for floating point texture formats: RHalf, RFloat, RGHalf, RGFloat, RGBAHalf, RGBAFloat.
- (819088) - Graphics: Fixed a rare issue that results in incorrect instancing rendering when multiple lights are used.
- (none) - Graphics: Fixed ForwardAdd pass z-fighting issue when the object is rendered with GPU instancing (for example when you have multiple lights).
- Surface shaders are automatically updated to apply the fix.
- For custom vert/frag shaders, instead of using the macro "UNITY_USE_CONCATENATED_MATRICES", now please use the new "#pragma force_concat_matrix" directive in the ForwardAdd pass.
- (821418) - IL2CPP: Fixed poor performance of string.Intern().
- (811511) - VR: Fixed GL.LoadPixelMatrix() not working when Single-Pass Stereo was enabled.
- (811571) - VR: Updated the following Image Effects from the Standard Assets to work with Single-Pass Stereo; Ambient Obscurance, Camera Motion Blur.
