Noise Generator

Generate organic Perlin noise patterns

Overview

The Noise Generator creates Perlin noise patterns - smooth, organic-looking random textures. Use it for creating cloud-like textures, terrain effects, or as displacement maps for other effects.

Usage Tips

  • Lower frequency values (0.01-0.05) create smooth, cloud-like patterns
  • Higher frequency values (0.1+) create more detailed, grainy textures
  • Combine with color adjustment nodes to tint the noise
  • Use as a mask input for organic fade effects

Common Pairings

  • Adjust HSV - Colorize the noise pattern
  • Merge - Blend noise with images for texture overlays
  • Mask - Use noise as an organic mask

Gotchas

  • Output is grayscale by default
  • Very high frequencies may produce visually chaotic results
  • The pattern is deterministic based on position (same size = same pattern)
