I have padded / atlas textures I would like to use in a billboard material I am making. I am trying to figure out a way to both isolate the correct part of the texture, and be able to do operations like panning and tiling on it without getting the rest of the texture in the image. Right now, I can get the cropping looking correct, but then when I offset it or pan it, I see the rest of the cropped part of the image.
I tried passing my UVs through to a custom UV channel but that didn’t seem to help.
I would greatly appreciate any guidance!
