I am going to sound a note of discord here, but I find the whole notion that the renders of props or figures can somehow me controlled by the creator after release of the mesh, to be absurd. The mesh itself, certainly belongs to the person who made it and how it is distributed, is up to this person. But renders of this mesh? It is silly to entertain any ideas of control. Anyone, so hung up on notions of financial gain derived by others, should either sell the mesh or keep it to themselves.
