With 4.24, GTAO was added, a new alternative to SSAO. It’s supposed to be a lot more accurate than SSAO.
With 4.24 Preview 1, I was successfully able to test GTAO, and it looked very good. The only problem I had was that it didn’t correctly work in VR, GTAO was only visible on one eye and the other eye didn’t have any AO.
But after 4.24 Preview 2, I could no longer get GTAO to work at all - enabling it just doesn’t do anything any more. Enabling it should be possible simply by doing
Doing that in 4.24 Preview 1 did disable SSAO and enable GTAO correctly. Doing it in 4.24 Preview 2 and Preview 3 and Preview 4 just makes all AO disappear, GTAO doesn’t appear.
Did anyone have more success in the recent preview versions with using GTAO? Could anyone from Epic maybe chime in about how to enable it?
