MTOA isolate UDIMs

[Shyralon]

Hello everyone!

I have a workflow question regarding how to properly use UDIMs with mtoa.

Right now I have a character which has 5 UDIM tiles, like this:

Now I need to to some adjustments in the shader using aiLayer which uses a mask.

But in this case I would only need the mask and adjustments to happen on the 1001 tile, since it is makeup on the head. If I just apply it, the maks obviously repeats over the entire body, so is there a way to specify a specific UDIM tile to be used? Of course I could just create further black smaller textures so the mask uses the UDIM format as well but that seems to produce a lot of useless data and is not really nice to handle. Is there any good way for doing it?

Thought I could do it through the "explicit tile" UV tiling mode, but it is still repeating to the arm and other areas.

Thanks for the help!

You can use an aiUvTransform node and put wrap U to clamp or color.
