SSAO seems to have no impact on my scene

I was trying to make areas receiving less llight appear slightly darker (soft shadow), so I thought of using ambient occlusion (SSAO) just like in, but it seems to have no effect, the area behind the furniture should be darker than the rest of the wall right?

onlyAO = true

onlyAO = false

I’m not sure the SSAO is working right now, see

Also see Ambient occlusion (shadows) on the ground

This should be fixed now, see
