Pixel-art lava flow with glowing cracks
In your harnessProcedural textureMIT
Generate a tileable pixel-art lava tile at a chosen art resolution: dark crust plates with lit and shadowed edges over glowing cracks with a pale core, or crust islands in a bubbling lava lake, with an emissive map and per-pixel normal, height, roughness and occlusion maps. Use for volcanic 2D game levels.
What it takes and gives
- Entry point
- generate
- Maps
- albedo, normal, roughness, height, ao, emissive
- Parameters
- art_pixels, plates, crack_width, crust, bubbles, hot_spots, relief, hue_shift and 2 more
- Presets

- yes
- Command line
- python pixel_lava_flow.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. A still frame of stylized pixel art, not a flow simulation, and it does not animate; for motion, cycle seeds or shift the emissive strength. The glow is a fixed three-step colour scale of distance to the plate border, not a temperature model, and the albedo also holds the glowing colours so the tile reads without lighting. Plates are Voronoi cells. Emission strength is set in the engine; the map holds colour only. Output sizes that are not a whole multiple of art_pixels give art pixels of unequal widths. Occlusion is a blurred-height estimate posterized to eighths.
