I’m wondering if it is at all possible to give the same object multiple UV maps? More specifically, can I unwrap a UV sphere (for example) and manipulate the UV faces in a certain way and save that UV map, then unwrap the same faces again and manipulate them differently and save that map separately - in order to be able to use both simultaneously for different materials?
Basically what i’m attempting to achieve is having 2 differing UV maps on one object so that I can use one for diffuse/glossy image textures, and the other for specularity/bump mapping.
you can have multiple uv maps (look for the option in the object data tab (next to the modifiers tab). There you can create/name and choose active uv map. To use those uv maps for different things it depends on the application (in Unity second uv map can be used for lightmap, but diffuse/bump use the same)
