Bug Ambient Occlusion makes a transparent hole in my image (or shows weird artifacts)

I am trying to render a simple image on a transparent background using:

• Unity 2021.3.4f1
• built-in render pipeline
• post processing v2 package

However, AO seems broken:

• Scalable Ambient Obscurance always cuts a hole in the image
• Multi Scale Volumetric Obscurance gives some weird artifacts

I am rendering to R32G32B32A32_SFLOAT Render Texture via Recorder. All other post-processing effects are disabled.

 

What happens if you disable recorder? I'd expect the SAO to work in that case at least. For MSVO, at a guess, try changing your camera clipping plane values around a bit.

 

Thanks for the reply!
SAO works fine in-game, at least while you don't use your render target alpha channel. But I am not making a game, I just want to render this image on a transparent BG
Never thought about the clipping planes thing! Didn't know this can be related. Changing values had some effect on the artifacts, they were jiggling and moving. However, this didn't fix the issue, as the artifacts are always present.
