Yes you are right forgive me, I have a bit of confusion in my head. Basically what I’m trying to do is to assign to my hisms, one of multiple textures in run time at random, while they spawn. I thought about it to reduce RAM waste. So if the value is one for example, it should pick color/rough and normal on 1. And so on, for all the sets I want to create.
So in addition to this, randomization and recycling, I wanted to know if there was a way to isolate and perform correction actions on single uvs in the same udim. To understand if I can best reuse a trim sheet on multiple different meshes, or if I should create different trim sheets for each of them. Considering that I have merged meshes. I hope you understand what I mean.
