Hello! That helped a lot! I am now understanding how this works better. With that said, as you can see in the first image, that is from Maya LT. You can see the UV's are stretched to the other tile. When you try to load that into Substance Painter, you will get an error that your UV's are crossing over tiles. Check. In 3DC, I have no way of knowing ( as far as I'm aware of ) that the UV's are crossing over tiles. Is this a function that I just haven't turned on for the UV Preview looks correct. Thanks!
Hello! I have a model that has multiple layer sets and I'm trying to separate them correctly. I moved the face and hands to it's own layer by creating "Add new UV set" and then selecting the faces in the UV Preview. I then used the Move Set and it moved them into the new layer. I then Apply UV-set and tried to open in Substance Painter and Maya LT. Both of them showed me that the UV's are outside the 0,1 bounds. I'm pretty sure I missed a step somewhere. If someone can point me in the correct direction. Thanks!
