wgt01: tileset build guide + 40-tile generator kit
AGENTS.md: NWN:EE tileset construction reference (constraints, .mdl/.wok walkmesh rules, .set format, Blender->NWN pipeline, prototype->NWN mapping). wgt01/: Westgate Urban Foundation MVP kit. - generator/tiles.py: single source of truth (40-tile table, materials, 12x12 test map, pure paint/height/walkmesh/.set derivations). - generator/build.py: Blender 4.0.2 scene generator (VIS_/WOK_/BLOCK_ per tile, edge metadata, library grid + 12x12 district previews). - generator/make_wok.py: ASCII walkmesh emitter (verts+faces+surfacemat+AABB tree) from the same geometry. - generator/make_set.py: first-pass twu01.set (CRLF) from the tile grammar. - flake.nix: build/wok/set apps + dev shell (pinned Blender 4.0.2, NWN tools).

"""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.
