Document the larger asset set produced by the running Blender generator (tools/blender_assets.py): 8 NPC character variants, 18 gear pieces, and 22 street/venue props with a manifest, editable sources, and preview sheets. - TODO gains Phase 3.5 with the audit/budget reconciliation (npc_casual is currently 7,756 tris / 5,616 verts, above the 6,000/4,000 contract), character selection by role, gear attach points, prop replacement/placement, emissive wiring, budgets, and screenshot gates - PLAN's Visual Quality Direction describes the library, runtime selection, and offline fallbacks - docs/plan-graphics-v0.6.md adds the library contract/output table and integration steps, and points Phase 4 at the Blender props - MEMORY records the manifest-as-source-of-truth rule and the generator caveat Generated library files stay untracked until the running build finishes and passes the audit; the generator itself is committed so the plan is reproducible.

"""Blender-authored NPC characters, NPC gear, and street props for Gig Line.
|
|
|
|
Everything here is modelled procedurally inside Blender (flatpak, headless) so
|
|
the assets are reproducible from source. Outputs are staged for *later*
|
|
integration: nothing in the game loads them yet (see
|
|
`docs/blender-assets.md` for the integration contract).
|
|
|
|
# build every asset (or --only name,name) -> assets/models/blender/**.glb
|
|
flatpak run org.blender.Blender --background \
|
|
--python "$PWD/tools/blender_assets.py" -- build
|
|
# Cycles preview renders -> docs/blender_previews/<asset>.png
|
|
flatpak run org.blender.Blender --background \
|
|
--python "$PWD/tools/blender_assets.py" -- render
|
|
# outside Blender (stdlib + Pillow)
|
|
python3 tools/blender_assets.py audit # GLB contract checks
|
|
python3 tools/blender_assets.py sheet # contact sheets from previews
|
|
python3 tools/blender_assets.py list
|
|
|
|
The flatpak sandbox cwd is /app/blender and it cannot read /tmp, so every path
|
|
is absolute and derived from this file's location.
|
|
|
|
Conventions (Blender is Z-up; the glTF exporter converts to Godot Y-up):
|
|
* the front of every asset faces Blender -Y, which becomes Godot +Z (the
|
|
NPC face direction used by `NpcAvatar.yaw_towards`);
|
|
* grounded assets have their origin on the floor (min y ~= 0);
|
|
* characters reuse the npc_base contract: mesh node "npc_base", bones
|
|
Head/HipL/R/KneeL/R/ShoulderL/R/ElbowL/R/HandL/R (+ Hips/Spine/Neck),
|
|
material slots skin/cloth/pants/accessory/hair, same joint positions;
|
|
* gear is authored in attach-point space (see GEAR_ATTACH).
