Thanks for your idea. But I don't get the point. Here is an example :

One shader using two textures. Texture A use uv, and texture B use uv2. Then
I would like to render map an object using this shader.
So I create an other uv (uv3) to unwrap my uvs (as for example, uv and uv2
were create before a copy sop). How can I setup mantra -u to render in the
uv3 space ?
