HI Sebastian, thanks for the reply. I also have vegetation generated on the GPU, works really fine - like 5mil trees on 60Hz. Now I want to try HW instancing for moving models - your NodeVisitor is good idea to have any geometry instantiable.
What was your start point? Did you also try the code from the blog I found or you did it your self? For some reason the code on the blog is not working and I am struggling to try to fix it since it has really nice implementation and ideas I am learning now.
