Dirt Texture


The Dirt texture can create different shading effects based on ambient occlusion calculations. This texture is useful for simulating dirt, dust, or wear and tear, as well as blending textures based on the recesses of a surface.


Users often connect the Dirt texture to the DiffuseAmount of diffusion, or the reflection of light photons at different angles from an uneven or granular surface. Used for dull, non-reflecting materials or mesh emitters., Bump, or Transmission inputs of an OctaneRender® material.
