For the life of me I couldn’t figure out why after creating a square document size, then morph flattening the uvs of my mesh via UV map subpallete and pushing “F” to frame the uvs so I could finally “grab doc” a copy, upon reapplying them to the mesh, they didn’t they didn’t line up correctly - an offset scale issue, not a flip vertical issue. (My plan was to go into projection master with these flattened UVs, paint them and grab doc from there).
The solution was to set the “angle of view” in the draw menu to 180 (pull slider all the way to the right).
Again, for beginners, if you want to use a shader material on these flattened UV’s in Projection Master, as opposed to Flat Shader which just gives you just the color information, to get some interesting results, be prepared to clean up the edges of the uvs later, since they will also inherit the shading.
I hope this helps someone and/or gives them some new interesting thing to play with.
