I am curious why and how pixels3D was able to provide a lightning fast AO shader with raytraced shadows and now NOISE in it. They use a REYES render engine. it would be great in case Blenders AO could better use HDRI images. for stills you could use bake to speed up rendering. claas mh the shadows look very very dark.

First Vector blur and now ambient occlusion is simply amazing. Wow, truly impressive. First Vector blur and now ambient occlusion is simply amazing.

Node Animations - that's an advantage in compare to mapzone. This technique is cool, nodes are cool. :) Heh… it actually inspired me… and I spent whole day on just doing some abstract node animation.

Even with its limitations, it can still be a tremendous time-saver for pre-vis. It should do fine in most cases, though. Thanks!! This is awesome!

I have never had speed issues with the normal AO, while I compliment the effort, the quality loss for speed increase really does nothing for me. I usually use AO around 2-6 on HD renders. Textures let you get away with this. When I need high settings, I bake it or use yafray (which tends to be way faster in skydome mode). I am sure someone will find it useful so thanks for sharing! -- KevinW well… meh… I have never had speed issues with the normal AO, while I compliment the effort, the quality loss for speed increase really does nothing for me.
