Random scalar shader

This scalar shader returns a random value between 0 and 1. The node picks a random number for each instances where the material (with random scalar shader) is used.

This can be used for “Switch BSDF” to create a pseudo-random distribution of a list of bsdfs on different instances.

If it is used in different material, it’s recommanded to change the seed for each call.

Parameters

name type description
seed integer The seed for pseudo-random value generator (between 0 and 255)
