Terrazzo

In your harnessProcedural textureMIT

Generate tileable PBR maps of terrazzo: stone and glass chips of many sizes set in a cement matrix and polished flat. Use for floors, counters, stairs and wall panels.

Render of Terrazzo
The render its check recorded in Godot 4.7.2, 256 by 256 pixels.

What it takes and gives

Entry point
generate
Maps
albedo, normal, roughness, height, ao
Parameters
chips, smallest, largest, angularity, polish, hue_shift, saturation, brightness
Presets
default, venetian, pastel, noir, glass_honed
Tileable
yes
Command line
python terrazzo.py --size 1024 --seed 7 --preset NAME --out DIR [--width W --height H] [--set NAME=VALUE] [--directx-normal] [--orm]
Godot material
material.tres
Blender builder

Limits. Chips are random polygons that may overlap; real terrazzo is packed by casting and grinding. Chip colours are flat with slight variation and no internal veining. Relief is very shallow. Occlusion is a blurred-height estimate.
