In Marmoset Toolbag, if you're baking with multiple texture sets, there's an 😠 OLD 😠 bug that can cause Padding to break on maps like AO (and more). This can lead to issues like white seams in the AO map. Image 1: multiple setsImage 2: one set @EarthQuake Are you still there or in contact with them? You've mentioned a fix…
I'm not sure what the problem is here. It looks like in the first image there is a single texture set, and the second image has the same texture set but some of the meshes/UV islands have been removed? Can you explain the process and what you're trying to accomplish?
