global noise layer on packed geometry

I have a scene with packed geometry and want to apply a global noise layer with e.g. an override material. How would it possible to achieve that?
Effect should be that the noise is different on my scene geometry and not the same on each of the models.

Unpacking would solve it for a simple scene but not for a very complex scene where I need the packed geometry.

Thanks for any hints.

Well, I guess the way is to make some random attribute at the packed primitives and drive some noise texture parameter by it (“origin” maybe).

for the love of god, thank you !!:roll_eyes:
