Also solved the problem with Amapi Designer 7. When poser exports the .obj it also exports the materials. When Amapi imports it creates meshes for each material. So I found that by removing the materials Amapi imports the .obj as one mesh with the same number of verices. Its just that Amapi has some excellent tools for selecting points & malipulating the mesh. And having got the hang of a fair proportion of the program Im reluctant to go elsewhere.
