Hi, does anybody know how to use the 2nd uv channel in maya? I want to create a blinn shader with the 1st uvchannel for the colormap and stuff and the 2nd for shadowmap and alpha. Anybody knows how?
So I unwrap my model in the 2nd channel so it can be all nice and prepared for lightmapping and collapse the unwrap modifier down. Now, a while later I add some more stuff to the model and need to edit the 2nd UV channel in order to make sure all the changes are corrected but all the unwrapping I did before has…
