I recently got to make a trimsheet tutorial for Experience Points!
The tutorial is actually on making a 2:1 ratio trimsheet and goes over how to properly convert trimsheet workflow into a 2:1 space. I also map the texture to the models you see above to demonstrate how to map it using the default Blender tools but the same principles apply in any 3D program.
