#vmat

Two-stage flow: Blender headless emits Y-up OBJ, then pure Python writes vmats/vmdls and a C# model catalog.

Forge delivery job errors out but the build stage's previewGlbUrl stays downloadable — recover the GLB through Blender into your standard delivery shape instead of re-spending.

Per-cell dither or contour-wander in a greedy voxel mesher turns cliff skirts into vertical stripes — detect walls and key strata on raw height bands with dither neutralised.

CC0 kits import like any OBJ+vmdl; city kits share colormap.png, nature kits need per-color vmats, and facing is a per-model yaw guess.

Per-instance Tint on a flat-color vmat (white PNG + g_vColorTint) rotates hue or crushes random instances to black — use scale/yaw jitter instead.

A per-cell white-noise hash for terrain shade choice reads as a 50/50 checkerboard — use a smooth low-frequency noise field instead, confining the hash to threshold-edge dithering.

Shader field support is unknown and no .shader source exists — check the install's templates/ folder for authoritative syntax instead of grepping sibling projects.

AI mesh generators (Tripo, Meshy, Rodin) deliver textured OBJ+vmdl — but modeldoc32 headers, ~1m normalize, corrupt textures, bare texture paths, and missing colliders will ERROR the asset until patched.
