Here's a bass guitar that's completely triangulated. BTW, Blender can triangulate automatically using CTRL-T (in EditMode).
Thanks. I know this shortcut and the geometries got triangulated in blender. But they seem to have been exported un-triangulized. Your model loads fine. May I commit it into xith-tk repository? Or will you?
Oh, I almost forgot to ask, does this work with Blender materials, besides textures (as in plain old color)?
Textures are cared of. Though I haven't tested it with textures. So the answer is "yes, it should"
