Here is the scenario\workflow I desire. Please tell me if this is possible.
I want to be able to create my character using sculpt and Multires… Lower the multires level and create shape keys. Bone and animate the character and then raise the setting on multires to the highest level for rendering.
Currently if you try to create a shape key on a Multires mesh, you get a pop up stating this is not possible.
Is there another workaround to this problem… ie is there a way to bake the displacement to a image map and apply the map to the low res model… then use subsurf to match the subdivision level of the high rez Multires model for rendering so i can use shape keys?
