NVIDIA GameWorks Integration

No idea. Try loading the NVIDIA Flex demo project and see if they work. Or otherwise share your project with me so I can see if its working properly or not.

The Flex demo project I found was in the link provided by CryZenX at watch?v=Sr7ptXOUHMo

Works in your build, cheers. Surprisingly fast (my goodness Nvidia really wants to destroy AMD and Intel GPUs with Gameworks).

One thing though, does anyone know where is the official Nvidia Flex demo project?

Edit: OK scratch that I found it (USE ONE), it’s in the Flex branch at /tree/FleX/FlexProject

Well to clarify, I had to reformat my computer over the weekend and Flex and everything worked perfectly before then. I have reinstalled UE4 and got the latest builds recompiled without errors but the flex interactivity no longer works…is it possible I missed some critical files outside of unreal? Do we need any files from nvidia for it to work?

[anonymous_user_bcf66e2c]

No you dont need anything outside of the repo. Maybe GPU drivers? As reported, FLEX is working for him, and is also working for me, using my build, so it will be a configuration with your machine I suspect, especially considering you just reformated.

EDIT: One thing that did occur to me, if your running in mode, FLEX will not work. So make sure your running in mode.

On the Nvidia side, I believe you just need the Nvidia GPU drivers with as well (“full install” of Nvidia drivers). No CUDA needed, that’s for sure.

Testing out VXGI with emissive materials using actual video files.

Was running at 90-120fps constant on my MSI 980 TI but recorded at 1080P @ 60fps

Testing out VXGI with emissive materials using actual video files.

Wow. Nice interactivity with video materials to boot. UE4 + VXGI does appear to be the frontrunner for full dynamic GI in games.

Has anyone tried VXGI on AMD? Hard to find resources whether it will work well on AMD (probably not the NvPhysX branch anyway?).

Update: VXGI + HBAO + FLEX + WaveWorks + HairWorks* confirmed working with latest. Have a good week playing with it all!**
*At least with Nvidia demo material etc.

I thought GameWorks would be really slow but Flex, WaveWorks and HairWorks seem to run OK thus far on my GTX660M. HBAO is not too bad. VXGI is quite different, of course. Certainly requires a card to even develop with it.

Hi!
I wanted to compile the Nvidia version of the engine, but I got stuck at GeneratingProjectFiles.bat. When I run it, it says something about missing .NET Framework 4 and mismatch between processor architect and MSIL. After that,it says Windows SDK 8.1 is missing. After installing Windows SDK, I could open the project files with Visual Studio 2013, but it says it’s incompatible with these files… My processor is an AMD FX8150, if it matters.
's a picture of command prompt:

Got it working, thanks for the update!
Anyone got tips though for making the hair look more like in the Hairworks viewer?
The hair strands are pretty thick and the materials look off. It also seem to ignore the settings I made in the tool.

Wow great sample. Would you please provide your sample so we can try it out? Thanks.

Hi , are you planning on getting VXGI to work with particles - i.e. having smoke illuminated by bounce lighting, or particles contributing to the voxel emissivity? was one of the features that stood out for me in the original Elemental tech demo.

Also, distance field shadows don’t seem to work with vxgi in the latest 4.9 release.

Particle lighting is planned, but I can’t say when.
I just did a quick test with DF shadows, and they seem to work as expected for spot lights, but the DF shadow setting does nothing for directional lights, i.e. a regular shadow map is used even when DF is requested. Is that what you observe?

Is it possible to have the Nvidia VXGI branch compile on Linux? It might require a switch to disable VXGI. Linux support is blocking me from considering VXGI because there isn’t a fallback to standard Unreal features. The ability to deploy to multiple platforms with the same project is fairly important.

Another similar request would be the ability to deploy to Nvidia Shield / Android devices with VXGI disabled (I don’t believe VXGI works on opengl.)

I’ll take a look at building the VXGI branch for Linux. It shouldn’t be too hard to just disable VXGI completely based on platform.

VXGI can work on OpenGL - although it requires a special build, and there is no GL integration code for UE4.

Well the bad news is, Turbulence won’t make it in. It uses an older version of the SDK. And is not compatible. If or sees , is it possible for me to get a version of the Turbulence DLL’s and libs that are compatible with UE4.9.1? So I can merge it in with the other GameWork techs.

I’ll pass your request to .

EDIT: I sent you the new DLLs, see the PM.

Hi people, is there any documentation on using game-works integration build? (4.9 with with VXGI, HBAO, hairworks, and all that good stuff); As in *settings *and how to change them - I want to edit stuff like HBAO intensity, colorbleed of vxgi etc.

Has anyone tried VXGI on AMD? Hard to find resources whether it will work well on AMD (probably not the NvPhysX branch anyway?).

I’ve only used VXGI on my HD 7850, it absolutely works but as you’d expect it’s too much for that class of GPU.

I haven’t seen anyone anywhere with one of the current high end AMD cards trying it out.

Unfortunately you will need to wait a little longer, still having issues building.

There is some doco in my branch, check the root directory, there are a couple of doc’s on how to configure things for VXGI and HairWorks at least. FLEX there is some doco in the branch somewhere. There is also doco in the official NVIDIA branches.

Cheers, indeed you’re the only one who’s commented on AMD VXGI from what I’ve searched.

I can’t get past the Shader Compiler Worker 1/1000.

I’ve tried rebuilding the program individually with no luck; every time I start up, I get that error.

[anonymous_user_bcf66e2c]

Open the console and type “r.hbao.enable 1” its defaulted to disabled by default it seems.
