Any ideas why the Ambient Occlusion pass in not show in Preview - neither with Classic Render Passes nor AOV outputs? The preview isn't even refreshing when switching to Ambient Occlusion.

Looks like a bug. It's not working on latest 27.16 for Studio+ license
CPU – i9 13900KF, 128GB RAM, GPU – RTX 4090
System – Windows 11

I only have 27.15 - the bug is there too. Let's hope a dev sees it and adds it to the list.

It's a current limitation due to the Shared Surface option. Just turn it off in the Octane addon options to be able to visualize the Occlusion pass.
Even if Shared Surface is on, the occlusion pass is generated correctly in the final render, by the way.

Thanks for the clarification. I will keep "Shared Surfaces" ON as it says that it improves performance and I don't often need Ambient Occlussion. But please fix it anyway. Cheers.
