[osg-users] 3D model preparation question

[Jeff White]

Thanks for the info. I had already checked the .mtl file and there are no 
textures referenced in this model.  It does everything with materials.  All 
material names in the .obj match what is in the .mtl file as well so I'm 
not sure what the problem is.  The paths all reference the current 
directory so those should be fine.

If anyone knows of a Blender export plugin for .ive or .osgb that might be 
helpful.  I haven't found one yet so I am assuming I will probably have to 
write one myself.
