I have used approximate ambient occlusion for several still renders and have been quite impressed by it. I recently used it for an animation and it didn’t go so well. There is an obvious flicker between frames where areas are alternately very dark or light. Here is a sample: http://rapidshare.com/files/141064077/flicker.avi.html
I tried increasing the “passes” setting from 0 to 1, but that increases the render time to the point of being unusable. Also, I’m not sure if that should be different from frame to frame.
This was rendered on a renderfarm. Perhaps unique hardware/software setups behave differently?
The meshes where the flicker occurs are clean, open meshes with no duplicate vertices or overlapping faces. The normals are all facing outward.
I know the feature works since it was used in Peach. I just can’t get it to work for me.
Any help would be much appreciated.
