 Calculating AO is fairly quick, but it is not something that can be done all the time. You can compute it by clicking the "​Ambient Occlusion:​Render"​ button in the [[light|Light Properties]],​ or by merely hitting '​O'​ in the [[tooltree_window|Tree Window]]. Editing the geometry of a tree will invalidate AO until the next calculation,​ though AO is computed when the tree is first loaded. Calculating AO is fairly quick, but it is not something that can be done all the time.

-With default settings, AO will most likely do a good job. However, you can further refine the effects of AO by modifying the "​Brightness",​ "​Contrast",​ "​Min",​ and "​Max"​ properties. Generally you want the very outside parts of the tree to be fully white. The interior of the tree should be dark but not black. The depth of the dark interior is up to the artist, depending on how dense and enclosed the tree is.+With default settings, AO will most likely do a good job.
