2023.2.0a16 onwards
Fixed a Metal validation error that occurred when GPU batched skinning generated an empty dispatch call due to empty blendshapes.
Reproduction steps:
1. Open project “ThreadGroupSizeMustBeAboveZero.zip”
2. Open “OutdoorsScene”
3. Enter Play Mode
4. Select “Triska/Genesis8Female/Genes8Female.Shape“ GameObject in the Hierarchy
5. Change the value of “Skinned Mesh Renderer/BlendShapes/Genesis8Female__G 101 EL Eyes 15“ through the Inspector
6. Observe the Console window
Expected result: No errors are thrown
Actual result: "Thread group size must be above zero" error is thrown
