Procedural textures & custom GLSL

Instead of an image, you can generate a texture for any map slot procedurally — noise, gradients, patterns, or your own GLSL — optionally animated.

Where: 3D editor → Material → a map slot → Procedural — Set a map slot to a procedural texture

Key ideas

• Generators: Noise (perlin/simplex/worley/fbm), gradient (linear/radial/angular), pattern (dots/lines/grid/checker/hex), solid color, or an image.
• Custom GLSL: Write a fragment vec4 proc(vec2 uv, float t) with helper noise functions and named uniform params that become sliders.
• Bake settings: Animate (re-render with uTime) or bake once; resolution 64–2048px.

Steps

1. Open a material map slot and choose Procedural.
2. Pick a generator (or Custom GLSL).
3. Tune its params; enable Animate for motion.
4. Use it on base color, normal, roughness, displacement, etc.
