Personal note: Aside from a software demo (+very small change to other demo) and a basic 3D character controller (which I need to work on again), I really haven't worked with this much.

I have been more focused on vertex color models and their use in Godot. Haven't done much here either... but have started a collection of materials, got billboarded models* working and a simple gridmap.

*=face negative Y in blender, apply rotation. Otherwise it will not export properly.
