Need some help with optimization

Hey everyone.

I’m doing this via my phone so I’m sorry in advance for spelling and typos.

Anyway, I’m trying to optimize my game and my big hang up is that I need my randomly generated obstacles to eat less resources.

each obstacle consists of a quad with an attached material for graphics. A script that initially placels it, moves it, land finally destroys it. And a custom collider mesh.

They are cloned from an off camera instance.

I’m currently making a texture atlas for the obsacles and rolling all of them into one prefab.

My question is, how can I do the collider mesh so that it’s not dragging around every collider fpr every instance?

can I just leave them all on the original and destroy the unwanted ones on the clones?

Sorry, my phone flaked out. Hope this makes sense.
