Random Node - How it properly works?

This is the question.

Luxcore:

Cycles:

You need 2 materials with different seed, another way will be use Object ID node

[B.Y.O.B.]

The "Random" node is a random number generator. The input value is mapped to a pseudo-random output depending on the seed and the input value. So you need to plug something random in to get something random out.

In short: it is not the right node for what you want to do.
As Shantarli said, use the Object ID node in "normalized" mode instead (it can be found in the "Utils" category). In LuxCore, object IDs are by default assigned randomly, so they can be used to get a random value per object as long as you don't set an object ID manually.

Big Thanks! I`ll try.
