AHA! Bloodsong, I think you discovered my subconscious need to make my own rocks! Actually, they do seem to have a little more variety than simnply 3, but that could be mass hallucination based on the power of suggestion. ;) Intersting, Orio... I have to get my mind out of "polygon mode" every now and then I keep forgetting the advances that are being developed what with transparencies, alpha planes, etc... I think I too will try some experments with various shapes which are polygon meshes, as well as "genuine" polygon meshes of simple, standard primitives, such as spheres. But, are the Vue primitives actually a Vue thing? They're always the same, so is there a way of knowing if they weren't simply made somewhere else and saved as .VOB models? I'm not doubting you, just wondering if it would even be necessary for E-on to have to come up with their own coding for something which is already readily available, such as 3D spheres.
