First post , and new to UE4, so bear with my noobyness. Sorry if has been discussed before. I’m trying to import an .apx Hairworks file saved out of the Hairworks viewer into the latest version of UE, but I don’t even see the .apx file option on the import list. Won’t read the .apx file, and drag and drop doesn’t work either. I’m using the regular version of UE 4.18.1 downloaded through the launcher, do I need to build UE from the source code to use GameWorks ? Many thanks. ---

The most complete version to date is the 4.17 [https://github/MaximeDup/UnrealEngine](https://github/MaximeDup/UnrealEngine) Keep in mind that using waveworks as it’s available from nvidia repository, and as i implemented it, rely on the usage of CUDA cores which means it will only run on Nvidia GPU. If you want extended usage, or even the CPU-based version you have to contact Nvidia for licensing. That’s what i understood at least. From /tree/UE4\_WaveWorks\_4.18 Readme file : “The UE4-WaveWorks branch offers you the opportunity to explore WaveWorks with the support of the UE4 rendering pipeline and editor system. The WaveWorks library provided in branch requires a CUDA-capable GPU. For builds supporting CPU and Direct Compute as well as licensing inquiries, please contact us at [EMAIL=“visualfx-licensing@nvidia”]visualfx-licensing@nvidia.” ---

Little update on my end (sorry for the new post, for some reason editing my previous post kept failing): I got the installed build working, finally! Now I’m going through and cleaning up things I never use in my projects, and optimizing a few things… I’ve got a respectable bit of performance in a test scene I whipped up. Averaging 40 FPS with VXGI, NVVL, and HBAO (on top of a few other post-process like motion blur, grain, bloom, etc). That’s at 1080p, on my lowly GeForce 750ti and i5. Getting the volumetric lighting (Nvidia’s, not Epic’s) to play nice took a lot of testing- boy is it finicky. Well worth it though. I intend to share my findings and set up for that once I get it down to a “science”, if one could call it that. No guarantees, but I may set up a good scene and walk through the settings (keep in mind there are settings in post-process volume, lights themselves, world settings, and a few console variables). I must have gone through ~10 whitepapers, dozens of forums threads, etc. to add on to the minimal knowledge I already had on Rayleigh, Mie, and so on. I think I’ve found some “sane” defaults for a standard outdoor scene. The screenshot below isn’t showing of the NVVL magic as I’ve tuned it way down, but rather the VXGI/HBAO. Once I have a cooler test scene setup and get my engine build more stable, I’ll pop back in share some more eye-candy. Oh, is running the 4.17 version, FYI. I’m not excited to go through the pain of getting an installed build set up again, but definitely want all the glory 4.18 had to offer, hehe. Epic needs to make area of the engine more approachable. It’s powerful, not doubt, but full of issues. Anyhow, candy (note that compression lowered the quality)! ---

You can read the GameWorks SDK EULA : [https://developer.nvidia/gameworks-sdk-eula](https://developer.nvidia/gameworks-sdk-eula). Note that you need to register, if you aren’t already. to follow the link properly you need to be logged in. Reading over it, the basics seems to be you can use it for commercial use, but you need to inform Nvidia about it, and they have the right to use images/video and what-not for showcase/marketing purposes on their end. That’s fine by me, as that’s free advertising, haha… If Nvidia were to use something you made, that’s always a good sign 😉 [Previous page](https://forums.unrealengine.com/t/nvidia-gameworks-integration/16686.md?page=207) [Next page](https://forums.unrealengine.com/t/nvidia-gameworks-integration/16686.md?page=209)
