This script "paints" uv-mappings with the model's vertex colors.
Usage:
With this script you can export uv-maps filled with vertex colors to TARGA
(.tga) images. To use it the mesh must have proper uv coordinates assigned
in UV Face Select Mode. And to fill the projected faces with color, the mesh
can also have material(s) and vertex colors painted on it.
The script has a GUI with a preview of the results and options like drawing
lines or not, defining size, etc. You can paint vertex colors in the mesh and
see the uv-map updated in the script's window.
Notes:
Material's rgb color is also used to fill the uv-map;
If there are no vertex colors or texture faces in the mesh and you press
the "Make" VColors button in the edit mesh buttons win, the current light setup
is saved as vertex colors for the model;
Check the script's homepage for example images.
