Is there a way to adjust custom vertex normals differently for each shape key of a mesh? I am making a model that attaches smoothly to a character, and am trying to match the normals of my mesh to the existing character model, but the normals only match up in basis shape key. Since the shape keys morph the two in different ways, the calculated normals change differently, I would like to adjust my mesh so that each vertex that lies adjacent to the character match up with the model in each shape key.
So basically I will need each shape key to have its own custom normals. I will do it manually if I have to. Can this be done? If not, does Blender have anything planned in the future for this? If not, what other software will do this? Thanks in advance.
