3dCoat 4.7.06
After importing model with only "Treat materials as separate textures" checkbox set on , everything seems to be ok, but ambient occlusion can be baked only for the first UDIM square. All the other (outside main UV area) don't bake http://take.ms/fi3PX
it's strange because Curvature is baking fine http://take.ms/ISAhF
