I was wondering what the best way is to cover large areas of my game with fluffy grass or plants.
Right now i'm using a combination of instanced models and billboarding. Looks pretty nice but I have to place every clump/plant/blade. So therefore I have to store patches of vertex data or point data for each area.
Is there some better way I can do this with maybe geometry shaders or a grass map or something (not really sure how that would work).
My current stuff look and works well enough but i'm slightly concerned about the scalability/performance of it and the amount of time it takes to actually place it all.
I'm interested to hear any thoughts/suggestions.
