This kit was created as a way to see if I could create unlit textures that still looked to have depth.  I created a single texture that had each shape at each shade variation I needed.  I outlined them all with the exact same shade, so it would blend perfectly around any corners.  I created the textures in Inkscape, and exported 2 copies:  one that was extremely low res so it would be easy to uvmap in Blender using pixel corner snapping, and the other at a much higher resolution.  I included the uvmapped texture incase anyone wanted to see how this would work.  Uvmapping coordinates are percentage-based, not pixel based, so switching from a low-res to a high-res texture worked perfectly.

After importing into Unity, I created a simple built in render pipeline Unlit shader that multiplied a texture with a color for easy tinting.  I used MAST - which is under my main page - to assembled everything and paint everything.

I hope these find use!  Please feel free to post in the kit's forum!
