> [@JGwinner](#): > > So my guess is, the “NVidia only” hardware constraint killed project?? Or is that an? There’s only few techs that are truly Nvidia-only on current GameWorks. Waveworks integration we get requires cuda and VXGI practically requires Nvidia + gpu. But Blast, Flex, Flow and Volumetric Lighting should run on AMD as well (as current Flex and Flow versions run on DX Compute), I’m not 100% sure about TXAA 3 or HBAO+ but I’d expect them to run on AMD GPU’s as well, don’t quote me on that tho. Anyway, it seems like RTX in particular is reason why Nvidia hasn’t been updating these techs anymore, has to be especially true for VXGI. Also UE4 using Blast for Chaos physics probably makes it difficult to justify a separate branch for Blast version that works with etc. ---

You can only reliably confirm other user is UE4 licensee by sharing the source code via UnrealEngine github fork or share modified editor via Epic Launcher (but there’s no such “modding” editor for GameWorks atm there so github is your only option). If github’s direct download fails, you can try cloning the repo with some git tool. ---

> [@TrinityMS](#): > > Are you planning on compiling for 4.22? It is very important for us. The most necessary - HairWorks+WaveWorks. Right now it’s looking like I’ll skip 4.22 for multiple reasons, I may try again on 4.23 but really hoping Nvidia would update these techs themselves for at least 4.22 as there are quite big rendering changes in the engine that makes manual upgrading for these less trivial. Also since UE4 has grown bigger, my compilation times on any recent engine versions are horrible, it takes few hours to get new build up and running on my computer which also makes upgrading and fixing these techs super slow (we are talking many days just waiting for computer to build things). I’m planning to upgrade my rig to a new 16 core Ryzen once it’s available (so in few months) and could then take a look again these for 4.23 but since the needed changes are quite big, I can’t give any promises at point. If Nvidia however comes with updated branches themselves, I’ll happily merge them even with my current computer. ---

I looked through the code, and it is because the author used an engine-code dependent method using the new “ShaderCore” split, which requires the Flex plugin to remain enabled in the engine. ---
