not quite, OpenSG only allows one material per geometry but more
than one texture per material. Attached you find our multitexture
test program. It is not as pretty as the tutorials but should help
to setup multiple textures. (Note, there are currently only
4 TextureCoordinate properties in the geometry, just in case
you try more).
