Peter explains how our new SSAO algo works:

RE: Tech Feature: SSAO and Temporal Blur

The first 10 seconds of the video makes me think you can use that, to do the new procedural created water decals shown in UE4 demo. (He takes the water globe and "paints" the floor wet)


I like the new options in the Debug Toolbar, will we keep most if not all the new ones? I would like to run around in my map with only that AO option(s) enabled and see the game in a new perspective.

I honestly didn't care much about the theoretical/mathematical portion (Which is most of it) but demonstrating it was cool.
So, if I can actually see it in front of me and play around with it. I think that will help me actually get deeply interested in the subject.



A video explaining in detail for the Debug Toolbar would be cool.

I've never been keen in Ambient Occulsion. I've always turned them off to improve the performance, but after watching this demonstration, i've finally understood the stuff behind it. It makes
objects look more dynamic and thus more realistic.

But i am still yet confused what is between HDAO,HBAO and SSAO.
How they differ from each other?

RE: Tech Feature: SSAO and Temporal Blur

SSAO is the general name for algorithms that generate ambient occlusion. There are plenty of SSAO algorithms.
HBAO and HDAO are the two standard implementations of SSAO.
