"""Single source of truth for the wgt01 (Westgate Urban Foundation) tileset.
|
|
|
|
Pure Python, NO bpy — imported by build.py (Blender), make_wok.py and make_set.py
|
|
alike. Defines the 40-tile table, materials, the 12x12 test map, and the pure
|
|
functions that derive visuals (paint), heights, walkmesh quads and the NWN .set
|
|
mapping from a tile spec. Blender realises these; the .wok/.set tools consume the
|
|
same data so nothing drifts.
|
|
|
|
Coordinate convention (matches KICKOFF.md): tile centred at origin, X/Y in
|
|
[-5,+5], Z=0 ground, Z=1.5 raised tier, Z=-0.3 canal water. Z up.
