You are assisting inside Blender to rapidly prototype a Neverwinter Nights: Enhanced Edition urban foundation tileset for the project “Shadows Over Westgate.”
|
||||
|
||||
The goal is NOT to build a full city tileset with buildings. The goal is to generate a reusable tile library of streets, sidewalks, plazas, alleys, ramps, bridges, canals/voids, drains, raised terraces, and foundation pads. Buildings, facades, lamps, signs, roofs, walls, doors, clutter, and district decoration will be modular placeables later.
|
||||
|
||||
Westgate’s intended atmosphere is noir dark fantasy: rain-slick streets, mercantile decay, old stone, smoke, fog, gothic silhouettes, and grimy desperation. The city also has an early industrial-magical layer: steam, alchemy, bound elementals, lightning engines, magical lamps, printing presses, and machinery beneath the gutters. For this pass, represent that only through ground grammar: drains, grates, canal cuts, raised streets, bridge foundations, dark cobbles, and industrial service channels. Do not make buildings.
|
||||
|
||||
PROJECT GOAL
|
||||
|
||||
Create a Blender scene containing a prototype tile library named:
|
||||
|
||||
Westgate_Urban_Foundation_MVP
|
||||
|
||||
Each tile must be a 10m x 10m square module suitable for later NWN tileset conversion.
|
||||
|
||||
Use metric scale.
|
||||
|
||||
Coordinate convention:
|
||||
|
||||
- Each individual tile is centered at origin when built as a source asset.
|
||||
- Tile bounds are X = -5 to +5, Y = -5 to +5.
|
||||
- Ground level is Z = 0.
|
||||
- Raised tier level is Z = 1.5.
|
||||
- Canal/void water surface, if present, is Z = -0.3.
|
||||
- Do not create true multi-level playable over/under spaces. Bridges may cross non-walkable canal/void areas only.
|
||||
- Keep walkable slopes gentle and readable.
|
||||
- Keep edges clean and snap-compatible.
|
||||
|
||||
Create each tile as its own Collection. Name collections exactly with their code and readable name, for example:
|
||||
|
||||
CP1_cobble_plain
|
||||
ST_S_straight_street
|
||||
RA_S_straight_ramp
|
||||
|
||||
Inside each tile collection, create these sub-objects where appropriate:
|
||||
|
||||
VIS_<tilecode> visual geometry
|
||||
WOK_<tilecode> simple walkmesh proxy geometry
|
||||
BLOCK_<tilecode> non-walkable blocker proxy geometry, if needed
|
||||
MARK_<tilecode>_* edge/debug markers, if useful
|
||||
|
||||
The WOK proxy should be simple and functional: mostly flat planes or simple ramp planes. Avoid complex triangulation unless necessary.
|
||||
|
||||
Use simple prototype materials:
|
||||
|
||||
- MAT_wet_cobble_dark
|
||||
- MAT_cobble_patch
|
||||
- MAT_plaza_slab
|
||||
- MAT_sidewalk_stone
|
||||
- MAT_curb_dark_stone
|
||||
- MAT_canal_black_water
|
||||
- MAT_void_black
|
||||
- MAT_ramp_stone
|
||||
- MAT_drain_iron
|
||||
- MAT_foundation_pad
|
||||
- MAT_debug_walkmesh
|
||||
- MAT_debug_blocker
|
||||
|
||||
Do not spend time on final textures. Use flat colors or simple procedural noise only. This is a geometry and tile-grammar prototype.
|
||||
|
||||
REQUIRED TILE LIBRARY
|
||||
|
||||
Generate these tiles first.

- Keep WOK flat.
|
||||
|
||||
4. AL1_narrow_alley_paving

||||
|
||||

BUILDER GROUP / PREVIEW ASSEMBLIES
|
||||
|
||||
After generating source tile collections, create a separate Collection:
|
||||
|
||||
PREVIEW_tile_library_grid
|
||||
|
||||
In this collection, instantiate or duplicate each tile in a neat grid with labels so I can inspect the full library.
|
||||
|
||||
Also create another Collection:
|
||||
|
||||
PREVIEW_12x12_test_district
|
||||
|
||||
Build this exact 12x12 prototype map using the generated tiles. Place each tile on a 10m grid. Each tile should be positioned by row/column, 10m apart.

Use tile names matching the generated collection names. If exact variants are not available yet, use the closest equivalent and note the substitution.
|
||||
|
||||
DESIGN CONSTRAINTS
|
||||
|
||||
- Do not model buildings.
|
||||
- Do not model full walls except retaining/canal/bridge support walls needed by terrain.
|
||||
- Do not model roofs.
|
||||
- Do not model decorative clutter except minimal drains/grates required to communicate tile purpose.
|
||||
- Avoid tiny details.
|
||||
- Prioritize edge alignment, walkability, and builder usefulness.
|
||||
- Keep polygon counts low.
|
||||
- Keep all tile edges snap-clean.
|
||||
- Avoid overhangs at tile boundaries.
|
||||
- Avoid geometry extending beyond -5/+5 bounds unless it is an explicitly marked harmless visual trim.
|
||||
- Use bevels sparingly.
|
||||
- Prefer clean simple geometry over visual polish.
|
||||
- Use material slots consistently so final textures can replace prototype materials later.
|
||||
|
||||
EDGE COMPATIBILITY
|
||||
|
||||
Think of each tile edge as one of these edge types:
|
||||
|
||||
FLAT walkable ground at Z=0
|
||||
RAISED walkable ground at Z=1.5
|
||||
CANAL non-walkable canal/void
|
||||
RAMP ramp transition edge
|
||||
MIXED special edge, document it
|
||||
|
||||
For each tile, create a custom property or add a Text object note listing its north/east/south/west edge types.
|
||||
|
||||
Example:
|
||||
|
||||
ST_S_straight_street
|
||||
N: FLAT
|
||||
E: FLAT
|
||||
S: FLAT
|
||||
W: FLAT
|
||||
|
||||
RA_S_straight_ramp
|
||||
N: RAISED
|
||||
E: FLAT
|
||||
S: FLAT
|
||||
W: FLAT
|
||||
|
||||
CE_S_canal_edge_straight
|
||||
N: FLAT
|
||||
E: CANAL
|
||||
S: FLAT
|
||||
W: FLAT
|
||||
|
||||
Add these notes in a scene text block called:
|
||||
|
||||
TILE_EDGE_METADATA
|
||||
|
||||
OUTPUT EXPECTATIONS
|
||||
|
||||
At the end:
|
||||
|
||||
1. Save the Blender file as:
|
||||
westgate_urban_foundation_mvp.blend
|
||||
|
||||
2. Report:
|
||||
- number of tile collections created;
|
||||
- any tiles skipped;
|
||||
- any substitutions made;
|
||||
- any geometry/pathing concerns;
|
||||
- next recommended pass.
|
||||
|
||||
3. Do not spend time making final art.
|
||||
4. Do not get stuck on perfect NWN export.
|
||||
5. The deliverable is a rapid, inspectable Blender prototype of the tile library and a test district.
