Eevee Script to create random color passes

Hi LoboTommy,

thank you very much for your advice.

Unfortunately, it doesn’t work.

But it doesn’t matter, because it’s not what I was looking for, here all triangles of an object are colored, but I need one random color per object.

Eevee does not have an object or material index, I asked here already.

Many greetings
Dito
