The Random Map node can be used to generate randomness from a connected texture map node across object instances. It is often used in conjunction with a Random Color Texture node to add more control over the random pattern which includes a Random Seed, Input Scale, and Noise Function parameter (figure 2).

Parameters

    • Input texture - The Texture to apply the operation.
    • Input scale - Scale factor for the input texture values.
    • Noise function - Noise to guide randomness.
