I was wondering. Suppose I have a 1000 grass meshes. They all have the same material, but I create them separately, because they look slightly different, because they have different heights.
Does my GPU speed up if I only draw one mesh over and over again? Or is only the material switching and uniform setting the main problem?
So: Should I consider going to only one mesh a 1000 times, or is it ok to have a lot of different meshes with only the same material?
