Ambient occlusion

Unity Engine
1

Hey guys, just made a long return back to unity ( from unreal) and have dived into the engine quite fast.

My biggest struggle so far however is to find out how i can add Ambient Occlusion (A.O) to my scene.
I’ve checked several video’s on youtube and constantly see people with plug-ins. there is an option under global Illumination (G.I) but for some reason when i check it and play with the sliders nothing happens.

Did i miss something or am I overseeing something ? I cannot imagine Unity anno 2018 without A.O :S.

You mean baked AO, or some form of SSAO?

(also AO is overrated)

Download the free post processing stack from Unity.

4

but where ? In the engine i went to Assets > Import Package > effects. checked several other packages but couldn’t find it. Any form of A.O would be nice ( not pre baked)

5

either really. Can’t get the baked one to work, can’t find SSAO ( though i could understand if the lather is a plug-in only)

Image Effects were replaced by the Post Processing Stack (Asset Store link).

Why?

When I enable G.I (this works) make my base cubes (test scene) static the GI seems to work, if afterwards I enable A.O nothing happens, I’ve been spamming it on and off, dragged the distance slider back and forth but no difference. I though maybe it’s because the G.I is dynamic, however when turning dynamic G.I off the G.I is gone and still no A.O.

Thanks, I managed to get it working with the official post processing package on the asset store :). Thanks for all the replies.

If you’re baking GI, you should not use the bake AO option. Ambient Occlusion is a cheap approximation of GI so baking it on top of GI doesn’t make sense from a realistic point of view.

If you need realtime AO instead, use the Post Stack that Mauri linked:
