Hello Everyone
I have to say that I have the exact same problem as Emmanuouel. I'm
loading an .obj file and I have no trouble displaying it. However, if I
want to change the TextureCoordinates of the GeometryArray I get an
ArrayIndexOutofBoundsException. It is interesting that I can get the
TextureCoordinates but I can not set them. I encountered this problem
when I tried to change TextureCoordinates for the ColorCube class. Does
anyone know how I can change the TextureCoordinates of the ColorCube?
Any help would be greatly appreciated.
