Very exciting project! Earlier I made a modular wall system, but your one is much better, the naming convention is really practical. For my RTS I want to make something similar, but on a pre-made landscape, where height is more problematic… What I miss here is how characters can walk up to defensive town walls, you could add stairs there, or use towers with inner stairs or ladders, if not already done. I found another project with procedural mesh based terrain generation, the 2 project could be merged somehow to provide full game nvironments.
