I'm hoping I can get more information on this post below because I wanted to use multiple UVs in a shader too, this time for emit maps. What script did Genjix use to export the second UV? And all you have to do is use or modify a shader to use the second set? Something like normalmap uv = renderbuffer2 emituv = renderbuffer3?
