set up AO but no AO

I have set post process volume into my scene and I checked “Use Ambient Occlusion” under world settings
but in Buffer AO shows strong Ambient Occlusion, and in normal render cannot see any Ambient Occlusion. Please Help!!!

If the surface is lit by direct light there won’t be much (if any) noticeable AO.

Not just that, AO isn’t use if you using dynamic solutions as far as I know. Even if the buffer still shows it.

Thx guys!!!:smiley:

Not true at all.
