Pixel-art crystal cave wall with glowing gems

In your harnessProcedural textureMIT

Generate a tileable pixel-art cave wall at a chosen art resolution: lumpy rock shaded from a top-left light, clusters of faceted pencil-shaped crystals with lit and dark faces, glints and outlines, and a glow halo on the rock, with an emissive map plus per-pixel normal, height, roughness and occlusion maps.

Limits. A still frame of stylized pixel art; the glow does not pulse or light the scene. The light from the top left is baked into the rock tones and crystal faces. Crystals are flat five-sided polygons with two faces, not modelled prisms, and on a 16-pixel grid they shrink to a few pixels. Rock lumps come from fractal noise. 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.
