My character is splitted into two meshes, one for head and one for body, each has its own single tile UV. 3. The seam appeared where the head joins the body. The solution:1.…

But yeah you can bake the maps in Toolbag, what you would want to do is: * Create a copy of your mesh with the new UV layout * Export both…
