I have a dilemma for game optimisation. I read somewhere that Blender renders a single large object faster than several small ones for a given number of polygons. However, I expect it is easier to cull smaller objects, so you probably win that way.
So here’s the question: Let’s say I have a forest scene with thousands of trees (which I do and it runs OK but I want a better frame rate). Am I better to have all the trees (crossed billboards) joined as a single object, each tree (a pair of billboards) as a single object (= thousands of objects in the scene graph) or somewhere in between (groups of trees joined as objects)?
Likewise with the terrain. Currently it is a single large object with many polygons. Is it better to break it up into smaller tiles or leave it alone?
Thanks
