How exactly do I do the changing to BitmapFileMaterials later part
code wise?
When I do:
= Obj.load("assetts/teapot_1.obj");
*** note no material specified
my object renders with a wireframe and a default color already. I just
need to know now how to apply (the code details) to load a
BitmapFileMaterial to it.
