I have a 3D model with a face shape keys that deforms the mouth/muzzle. What I'm trying to do is adding a new mesh (whiskers) into this existing face but have it deform along with the shapekeys. The new mesh does not have shapekeys yet. This model will be used in unity as a VRChat avatar.
the big question is, how do i "apply" this surface deform modifier to the whiskers mesh and join it to the face mesh, and still have it deform when the face shapekeys are used? the end goal is to have a single mesh, with these shapekeys deforming the face and the whiskers mesh like how i see it with the surface deform.
i have a lot of shape keys and not too fond of the idea of joining the mesh, then individually move the whiskers in edit mode for every single shape key.
