The last week has been a bit slow. My son got sick again and I got stuck in a hole with cleaning up a few things in my libraries.
Added support for multiple materials, 4 uv sets and vertex colours for the generated output. Also an optional colour palette for my editor. So when I have a fixed set of colours, the colour values map to a fixed set of UV values for a particular colour map. If the colour map does not exist, you can also have that generated from your selection of colours as well.
I can now start to sync up my two libraries, remove the C# implementation and start handing out some test builds.
