It's a little weird.. I have this shader up that uses channels 1 and 2. If I UV Map on channel 2, it shows up working fine in my shader. If I try to unwrap, and go to channel 2, it resets the UVs back to use channel 1... it's very odd.
I think by default it will just use Channel 1's UVs if Channel 2 doesn't have any UVs already assigned? Try doing something like adding a UVW Map modifier (plane/box/whatever) and make sure it's set to channel 2, then add an Unwrap UVW and see if that makes any difference in channel 2.
Well I'm a moron, so leave me alone Damn, I could have sworn I saw them work in the viewport (on a single material) in the past. That's what I get for being out of art for 2 years. Thx Vig, Ruz
Hey guys.. So I'm trying to apply a 2nd and 3rd uv channel to an object in Max. I do a UV Map modifier, select channel 2, and apply it. I go into the Unwrap, and it's using the same UVs as channel 1... I've tried applying it in different ways, and nothing works. One thing I have noticed is that in the past when I've used…
