Thanks Gster123, I'm not totally sure how to do that but I'll read up on it and give it a try! I managed to render everything again with more plants added and it worked but anything to make the process smoother would be good. Also I'm wondering, I made instances of one bush and placed them about, but the polycount still went up although I checked and they are all instances of the first, anyone know if this is right or not? It did render as if they were instances I think as it didn't take any longer than with just one.
