Re: A new kind of ball
Yep I use Wings3d, which is really nice.
Mapc's OBJ importer is does not support the entire OBJ spec (the importer code is actually only 80 lines of code), but it's sufficiently general to do whatever you want. Two limitations: all faces must be triangles, and all vertices must have UVs (texture coordinates).
The first limitation is easy. Just do a Tessellate Triangles while in Face mode. I usually save objects in .wings format and do the tessellation only for the OBJ export, since it's easier to model with quads and polys.
The second limitation can be an annoyance. You have to use either Image Snap mode or the UV Editor to assign a textured material to all surfaces. Once this is done, you need to rename the material in Wings3d to match the filename of the mtrl file you want. This is because mapc uses Neverball mtrl files instead of OBJ .mtl files, which have a different feature set. You can discard the .mtl file that Wings3d produces.
