Hi,

This is a small but annoying bug:

I'm working with some materials which have some textures which use different channel numbers (imagine a texture for some tiles surface and another to define the mortar grid).

In max I have two different UVW mapping with channels 1 and 2 for that object. If I want to show texture with channel 2 in viewport I have to make it 1, adjust and then set it to 2 again to render correctly. If it is set to 2 it shows in viewport like it was using the first uvw mappping.

Unfortunately it's not possible to display multiple UV sets when the material is set to show the final result (blending all the BSDFs and layers according to masks and weights). However, if you enable "show in viewport" on the individual textures, they should use the correct UV set and you will be able to tweak them without having to shuffle the sets.

I was thinking about referenced mxm. Does it always show "final result"?
Here the texture shown is mapped with the wrong UV set (but renders fine). I don't think it's trying to show the full blend.

Hm, I've just tested it and it seems to work fine. When I change the active texture in the MXM file, the viewport uses the correct UV set. Could you send me a minimal scene which reproduces the issue?
