Science fiction greeble panels

In your harnessProcedural textureMIT

Generate tileable PBR maps of science fiction greeble panelling: recursive rectangle subdivision into panels at different levels, with grille slots, corner bolts, recessed ports and light strips in the emissive map. Use for spaceship interiors, corridors, machinery and mech parts.

Render of Science fiction greeble panels
The render its check recorded in Godot 4.7.2, 256 by 256 pixels.

What it takes and gives

Limits. Panel cuts snap to a 32 by 32 grid, so every panel is an axis-aligned rectangle with no diagonal or rounded panels. One tile holds one subdivision, so a large wall repeats visibly; vary the seed between surfaces. Light strips are emissive colour, not light sources. Occlusion is a blurred-height estimate, not ray traced.

Checks
command line generates declared maps, maps decode, maps have declared size and channels, maps tile without a seam, normal vectors unit length facing out, maps carry detail, godot imports the maps, godot material template loads every map, godot compatibility render, capture shows the textured surface, blender builds the material
Techniques
Recursive binary subdivision snapped to a grid, Constant-time panel lookup through a grid at the snap resolution, Per-panel hashing for detail types, Emissive map for light strips
