Yes. HeelX. I saw this but I am still not sure if A7 will support 2 uv-sets. I mean, natively, in MED. Currently there is just a new function for programmers.

I appreciate the work of Ventilator very much. Maybe this is the way to get 2 uv-maps. But he still has to create a tool that imports uv-sets. I hope he finds a solution for that. I wish him luck!
