in substance painter and marmoset toolbag the texture looks fine (straight lines on the pants) but in blender and maya it looks skewed, here are the images Blender: Substance painter
The skewing on the UV flat is because of this, but that doesnt matter as they are painting directly onto the model in substance, creating the desired result. The issue is that the display changes when importing into a different program-- which has nothing to do with the UVs. @juanoblagu Sorry to make you repeat something…
