I found this video for example of how to make decent looking grass. But I was wondering, what would be the best approach for a really big landscape area? Unfortunately I can't find videos about this topic.
So how would I put a hair particle system with high density across a big area? I tried to convert the particle system into an object (mesh), but at some point this also becomes pretty laggy and not really fun to work with, and I already have a pretty fast pc (5900X, 3080TI).
Do you have some good videos or keywords I can look this up with? Something that pushes me in the right direction?
