Re: Bake Ambient Occlusion with IvyGrower

how big did you make the texture? In the ivy object all the leaves are one object (well, one for the young leaves and one for the old leaves) and one texture map has to cover the whole surface area of all those leaves, so it would have to be big enough for detail. That goes for the color and the AO. It might be better to check out the help for AO and tweak the settings for speed (unless you are there already)
