Hi, I'm redesigning the Model classes in my engine to something more structured. Here is a proposed design: - MODEL class: Contains pointer to a MESH object, and position/rotation information - MESH class: Contains mesh data, animation data, UV coords, pointers to MATERIAL objects - MATERIAL class: Contains colour info, UV tiling/offset, pointer to texture object, pointer to SHADER object - TEXTURE class: Just a GLuint - SHADER class: Just a CgEffect object Where appropriate, file loading is done through a resource manager. Can anyone foresee any problems? Should I really separate the MESH class from the MATERIAL class, or have it all in one? Is it wise to have a shader belong to a material? Thanks in advance for any feedback

Sounds pretty good to me, just one note, you might want to add the ANIMATION resource and have mesh optionally contain a pointer to that, now you can also reference your animiations across mesh the same way you reference materials. Set to NULL and this mesh has no animation.
