Is there a way to turn an obj into a partial shrink wrap for another obj to deform into? As you can see in the image below, I have two faces. One with a complete head, and another as just the face. I'm trying to deform the one with a complete head to match that of the 'face'. Shrink wrap doesn't work as it just causes the entire head to shrink into the mask and I cannot combine it as the mesh for the head cannot be deleted/merged as I plan to use it as a morph target in Daz3d. Any help would be appreciated.
Shrinkwrap contains a vertex group field. Just assign the needed vertices in a group, and specify this group in the shrinkwrap modifier.
