Additional Notes

Any pictures where manny is visable or has a proper reflection is with Nanite disabled.
It might be releated to the GPU skincache, as without Nanite he is green showing it’s working but isn’t part of it with Nanite enabled.
I did find it works with InstancedSkinnedMeshes but not the standard one.
It also wasn’t in issue in 5.7.
