I followed your suggestions on your homepage tutorial, and attempted this, but I totally don’t get these results with my model (I requested the cube because it’s easy to model and unwrap, as opposed to making a character to unwrap). The various textures only show up on my character when I choose the appropriate UV Texture in any mode, and in one of the three (body, incidentally the first one) my character is completely untextured in object mode. In edit mode he is properly unwrapped though and only his body has the texture it’s suppose to.
I was told there’s a way to link from a 2.5x blend file into 2.49, perhaps if I can figure out how to do that I can unwrap my character there using the interface I know works for me. Which requires me to state, if it ain’t broke, don’t fix it.
I tried this experiment with a cube as well and I can manage to get it to display separate textures in object mode and edit mode, but in edit mode the UVs are overlapping each other in the UV space. I remember in 2.49 you would unwrap a section of a mesh and it would go to its own space, and unwrapping another section of the mesh would unwrap to another space without displaying the original even if you later selected all vertices. This seems like a step backward in functionality, displaying the complete UV on the same map when everything is selected.
