Hi, again, Gianni... I think our design approach is largely due to the fact that we only wanted to apply our material to very specific parts of the scene graph, and applying a material at a group node in our scene might cause unwanted material changes in other areas of the scene graph.
So, I don't think it will actually help you in your case (but I could be wrong; it happens often enough). Still, the approach has some merit if you want that fine tuned control (and if it worked the way you wanted it to work). Sorry I couldn't help more... D.J. On Wed, Nov 2, 2011 at 1:13 PM, D.J.
