I’m looking forward to your 4.192 Flex integration. I’m using your 4.192 version now, and it feels good. Also, ask the official Datasmith tools that don’t seem to be able to integrate into the branch engine. He seems to have been encrypted or what else has he done? It can not be rebuilt in the branch. ---

I’d start by checking the Nvidias VXGI test levels from Samples/UserContent/ (/Samples/UserContent). VXGI test levels are bit hidden, I didn’t have time to move them around into more logical folder. It also makes it bit more tedious for me to keep the samples up-to-date if I do as now I’m just keeping the samples on same folders as they are on each nvidia tech branch. > [@VinaCaptcha](#): > > Why do you don’t include Flex into version?

Thanks got HBAO+ Running trough cvar. But still the same result on the VXGI map by nvidia (CornellBox) no GI at all. I will try to download and build your other branch with just vxgi/flow to see if GI shows on that one. Update: I tried the other branch the same there. Is it just me having ? Update2: i think i found the problem LogD3D11RHI: Error: VXGI Error: VXGI requires a GPU that supports FP16 typed UAV loads natively (.3) or through NVAPI (+) when ambientOcclusionMode = false (GI\_Base.cpp, 366) LogD3D11RHI: Warning: VXGI support is limited to occlusion-only mode on GPU. So my guess is VXGI 2.0 only supports and onwards?

But like SteveElbows mentioned, it’s the Flex SDK, not the UE4 integration. Also since only exists in Nvidias GameWorks repo and not in their UE4 fork, I’m not allowed to distribute the Flex 1.2 SDK source code myself due to the licensing limitations. As soon as the UE4 integration comes live, it’s bound to UE4’s license and there’s no such limit anymore. > [@videoprice](#): > > We are waiting for UE 4.19 Blast 1.1.2 + Flow 1.0.1 + HairWorks 1.4 + HBAO+ 4 + TXAA 3 + Volumetric Lighting + VXGI 2 + Flex 1.2 + WaveWorks Regardless what happens with Flex, I will not merge WaveWorks myself for two reasons: doesn’t work on AMD and Intel GPUs + it had shader conflict with Flex in past. ---

Yes, I seem to have encountered several [Line:133] errors when I use the engine, but I don’t record the details, and then the engine will collapse and disappear.
