The problem is that you're probably wanting to use different
transformations on the different cores of the different parts, right?
That means that two vertices of a polygon would use different matrices
when rendered, and OpenGL doesn't support that directly. You can use
shaders or the old matrix_palette extension to simulate that behavior,
but OpenSG doesn't directly support this right now.
Sorry
