After the 3d model is broken up into individual pieces like this, is the mapping/placement of the pieces on the uv texture map arbitrary as long as triangles don't overlap?
My thinking is that the different texture atlases are placed in a uv grid, and the empty spaces between components (in the bottom right picture) can be filled with anything since they aren't mapped to xyz coordinates on the 3d model anyway.
