if you have your github linked to epic account (Iike needed with all ue4 forks) you can see nvidias development : /branches/active. As you can tell by looking at that, they only do RTX work nowadays, there’s been zero updates to traditional gameworks techs for a long time.
I’d like to but the rendering changes kinda make the effort pointless atm. I don’t know enough of the gameworks techs or ue4 rendering internals to redo their rendering code for 4.22+. Some of the techs can be ported to newer UE4, like blast, flow and flex, probably hbao+ too but you still wouldn’t get things like fluid rendering on flow and flex without the rendering code redo.
Blast is bit problematic as it’s being used bit differently now on Chaos, it’s technically part of the ue4 now but it doesn’t work with like the gameworks version did. And HBAO+ usage is quite marginal, especially since UE4 already supports SSAO on forward path now + they have GTAO which is superior to HBAO+ so I don’t know if it’s really worth the effort to separate it again from VXGI branch just to get it running on 4.24 etc.
