I have a head mesh with several blendshapes (Morph Targets). Some of the blendshapes and have painted weights (in Maya it’s in: Deform → Painted Weights: Blend Shape) to mask places where blendshape should not influece verts. It looks great in Maya and Motion Builder, but when imported in UE4, the engine doesn’t use those painted weights and masked verts are influenced by blendshape.
So the question is: are blendshape painted weights are supported in UE4, and if yes how to turn them on? If no, is Morph Target masking planned feature?
