Hi everyone,
I would like to randomize various materials over the polygons of an object.
Can be possible using ‘Fields’ ?
Cheers

Hi Alberto,

You can use the Selection Tag and place either the same or an individual Random Filed in each.

Please have a look at these two versions:

If you use the Random for each separately (…_01.c4d) then change the Seed Value for each.
In any case, the adjustment of the Fields Tolerance is crucial. Start by adjusting the most right-sided (Object Manager) and then the next to the left, to get the distribution you want.

A different effect can be achieved with a Vertex-map and the Vertex Shader.

All the best

P.S.: Here is the setup with Vertex Maps. Also here, one version with a central Random Field, and one version with individual Random Fields.
