SkinnedMeshRenderer.skinNormals deprecated in 3.4?

Hi,

I just noticed that I can not edit the skinNormals property in the editor in 3.4, and the script API says that this is deprecated.

Why is this? I could not find any explanation for the change in the 3.4 or 3.4.1 changelogs. Is it always on? (I have lighting problems with a skinned mesh and thought about enabling this to fix them)

Yes, it is always on if the shader requires normals. It was deprecated because the current optimized mesh skinning code was not actually faster with normal skinning disabled.
