I’ve got a thread, but havent fixed automorph yet. Since in its current configuration, the modifier will override effect of shape keys. To be able to utilize it with shape keys, I’ll need to convert the deformation into tangent space. And reliable generation of tangent vector is currently a problem for me
What I got already is “mesh decal” system. In particular, MeshDecalVD node group. It utilizes vector displacement to place a “sculpted” detail on a mesh, at the position specified by a dummy. Could be used for cartoon mouth rigs, if everything will go right. I’ll make an experiment with a character soon
