>From the tutorial and example programs, it appears there are two ways to assign materials in OpenSG: either assign them to each individual Geometry node or make a Node with a MaterialGroup core. Assigning materials to every Geometry node seems a bit cumbersome to me. I'm told the MaterialGroup core is dangerous because it overrides materials beneath it on the graph. Please correct me if any of this is wrong.
When I speak of materials, I'm not just talking about traditional OpenGL material properties but also textures and shaders. I believe this is the same way OpenSG thinks about materials. Anyway, I'm accustomed to the model used in other scenegraphs where you can assign individual material properties (not just complete materials) to any node, and those properties affect all nodes beneath them. So the material properties closest to the geometry leaf nodes are the ones used, unless some override method is in use. I always found this method of assigning materials very easy to use, so I was wondering if there is a similar method in OpenSG that I just don't know about or if there is a plan to make one. -- Terry Welsh - mogumbo 'at' gmail.com www.reallyslick.com | www.infiscape.com | www.vrsource.org ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
