Lack of SSAO controls in UE5 especially when I'm unable to use Lumen/GI

HI,

I understand Lumen has replaced the need for SSAO, however there are situations where I am unable to use Lumen/GI (low end platforms/3-4 player split screen disables lumen etc).

SSAO is on as i can see a difference when i toggle it on/off, however i dont appear to have any controls. Even the console commands dont seem to be doing anything to adjust the look of it.

There are no setting in the Post Process for SSAO either that a lot of internet resources describe and using DFAO works only when i set the skylight to movable, which gives good control but results are too noisy/jittery to use.

Any help greatly appreciated.

Thanks,

Leon.

Hello,

These CVars all apply to SSAO:

r.AmbientOcclusion.AsyncComputeBudget r.AmbientOcclusion.Compute r.AmbientOcclusion.Compute.Smooth r.AmbientOcclusion.Denoiser r.AmbientOcclusion.Denoiser.* r.AmbientOcclusion.DepthBoundsTest r.AmbientOcclusion.FadeRadiusScale r.AmbientOcclusionLevels r.AmbientOcclusionMaxQuality r.AmbientOcclusionMipLevelFactor r.AmbientOcclusionRadiusScale r.AmbientOcclusionStaticFractionIn addition to this, the Ambient Occlusion section of the Post Process Volume controls SSAO.

Please let us know if this helps.

Thank you. I think part of my original problem is the SSAO doesnt do anything when Lumen is on for obvious reasons and i was just getting caught out.

All good now, thank you
