Mixture Of PTEX And UVs On A Single Model:
Currently once a model is setup for PTEX, there's no way to also
use UVs on the same model. Just like sometimes its easier to have 3-4
differently configured uvs sets on a single model, sometimes it's nice
to have uvs for a model (like say if you have a layer that's best made
by mapping a repeating pattern on a 2d surface in a 2d paint program
like photoshop), and other paint layers would be best using PTEX
(something you don't want to be distorted by your object's UVs). For
example, lets say you have a tree, you want the bark layer to use ptex
since it's hard to map for that detail, but you also want a color
gradient travelng up the side of the tree, which would be best done by
mapping the tree from the side using a single planar uv set.
