When I place a bunch of speed tree bushes in my map...
The lighting takes a very long time to build, like around 30 minutes, why is this? I was hoping I could add speed-tree bushes to my map (Like in DM-Gateway) but why does the lighting take such a long ol time to build?
For the same reason rendering an image in 3DS Max or Maya that has a bunch of opacity/alphas (like for leaves, grass, etc.) takes forever, it has to calculate according to the opacity maps, etc.
