HDRP instantiating grass gameobjects in runtime huge slow down (Alternatives?)

Unity Engine

Hi! I’m trying to instantiate grass to fill areas of my terrain with grass, this has to happen in runtime, but instantiating 10k or 100k gameobjects causes a huge slowdown. What can I do in this case?

Edit: My process, I instantiate a grass game object that has only LOD 0 and culling and a custom shader for grass that works fine when used in terrain as a tree. So no performance issue there.

So apparently the problem was, i had a leftover “find gameobject” loop, which made the huge slow down, since there was thousand of gameobject to look from.
