hello, here is a use of an object AM with 3DCoat for painting.
It is quite possible to use 3DCoat texturing AM objects. color, specular, bump, bake ao, glow texture etc...
No problem with the uv with AM bake option. to export, I used the export obj * 16, with selected triangles. (Other division 32, 64 etc ... give a worse result)
And it work well
