Instanced Grass is parked for the minute. It works great and handles 500,000 clumps easily (start to run into memory problems after that just storing the transform for each). Anyway that’s far more than I’d ever need.
Moving on to rocks. These won’t actually use the instance renderer since I want to use that for things that don’t cast shadows and will be drawn in mega volume. I could enable shadows for it but obviously that would really slow things down.
So i’ll have large rocks that cast shadows and small fist-sized rocks that don’t which will be instanced.
I’ve got some nice rock models which only use a couple of hundred triangles.
I thought i’d add a video to give you the idea of how this all looks together.
