We used Amapi before buying Truespace.

Forget about Amapi and the other Eovia Products (besides of Hexagon) they are totally buggy and cannot export one single format without errors!

So if you want to prerender stuff, make a bitmap of the 3D mesh, this is okay, but if you want to use the mesh for your games forget about it!

TrueSpace is much better in that case.
