What is a good way to get changes made in another application back in to WM? for instance I come out of WM as Obj so that I can take the mesh tiles in to zBrush to make some changes and I would like to get the modified tiles back into WM to then apply some filters and make texture maps. then come back out as OBJ again with textures to take into Maya for Animation and rendering. so How to I get My modified OBJ date back into WM?
