+// Another Assimp OpenGL sample including texturing.

+// textures (by their material ids)
+//
+// Don't worry about the "Couldn't load Image: ...dwarf2.jpg" Message.
+// It's caused by a bad texture reference in the model file (I guess)
+//
+// If you intend to _use_ this code sample in your app, do yourself a favour
+// and replace immediate mode calls with VBOs ...
