Pixel-art water surface with wave glyphs and caustics
In your harnessProcedural textureMIT
Generate a tileable pixel-art water tile at a chosen art resolution: dithered depth shades, evenly spread wave glyphs, sparkles, an optional caustic light network and foam clusters, with per-pixel normal, height, low roughness and occlusion maps. Use for seas, lagoons, swamps and rivers in 2D games.
What it takes and gives
- Entry point
- generate
- Maps
- albedo, normal, roughness, height, ao
- Parameters
- art_pixels, waves, wave_length, sparkles, caustics, foam, depth_patches, relief and 3 more
- Presets

Limits. A still frame of stylized pixel art, not a wave simulation, and it does not animate; for motion, scroll the tile or swap seeds. The light from the top left is baked into the wave glyph colours. Caustics are a Voronoi line pattern, not traced light. Roughness and height are values per drawn class, and the normal map treats each art pixel as a flat facet. 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.
