NVIDIA GameWorks Integration

[GalaxyMan2015]

I'm starting to doubt if GalaxyMan is actually human.

Last time I checked I am still very much human, but maybe that is what i was programmed to believe :S

I think I have a non-stupid question.
How can I access the shader/material for hair-works? want that "use with vxgi voxelization" option ticked so hairworks can work with vxgi.

You can't, HairWorks does not use traditional material editor shaders. It has its own shader, which can be seen in HairWorks.usf. Special code will need to be written to handle VXGI voxelization I believe. I will look into it.

I'm trying to open a project with VXGI 4.9 Editor, but it compiles shaders for ages. I can see that Editor spawned 4 "Microsoft C/C++ Compiler Driver" processes that consume all the CPU, but there's no sign that the project will open anytime soon... Should I just wait, or is it some sort of anomaly that was not supposed to happen?

First time you run, the loading sequence will stop at 45% as it compiles the initial set of shaders, this can take a while especially on slower machines. After which it will continue to load, just be patient.

Gah, every time I try to rebuild ShaderCompileWorker I get this:

Something doesn't look right about that log, how are you actually rebuilding it? There should be no uproject files involved. All you should need to do is open the UE4.sln in Visual Studio, expand the Programs folder, look for "ShaderCompilerWorker", right click on it and click build.

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.
Here's a picture of command prompt:

Sorry for bothering, but can anyone help me?

So, I was using my project solution (which has everything in it, but ShaderCompileWorker didn't like that), so I went and used the UE4 solution and rebuilt it just fine. Still getting this, though:

Your error is a strange one, looks like some pre-requisite is missing, causing all sorts of problems, unfortunately I cannot be more specific, as im not sure what you would be missing

Open up ShaderCompilerWorker.cpp and check that you have the following lines, starting at line 18:

// NVCHANGE_BEGIN: Add VXGI
#if WITH_GFSDK_VXGI
// This version number is checked at load time in Engine\Source\Runtime\Engine\Private\ShaderCompiler\ShaderCompiler.cpp
const int32 ShaderCompileWorkerOutputVersion = 1000;
#else
const int32 ShaderCompileWorkerOutputVersion = 1;
#endif
// NVCHANGE_END: Add VXGI

Then open ShaderCompiler.cpp (located at Source/Runtime/Engine/private/ShaderCompiler) and make sure the following lines exist, starting at line 188:

// NVCHANGE_BEGIN: Add VXGI
#if WITH_GFSDK_VXGI
	const int32 OutputVersion = 1000;
#else
	const int32 OutputVersion = 1;
#endif
	// NVCHANGE_BEGIN: Add VXGI

If either one is missing, then your build is wrong (Will need to re-obtain and rebuild). If you do have both, then im not sure what to say, it should work. I would suggest at that point, maybe putting a breakpoint in ShaderCompiler.cpp and see what is happening.

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?

f
I am still not able to use the FLEX integration...really bizarre...I have two different builds now one just FLEX and one full gameworks integration...hairworks, VXGI, all of that stuff works fine but FLEX still won't!

Does FLEX work in the official NVIDIA branch version? I can only guess is you dont have a compatible card. Or compatible drivers. I would suggest maybe downloading the standalone version from the NVIDIA Developer portal and see if you can run their examples exe, if that doesn't work, then thats a sure sign that either GPU or drivers are wrong.

i downloaded the ZIP, extracted, ran the Setup.bat, ran the GenerateProjectFiles.bat, opened the .SIN in VS community 2013, ran Build on UE4, hit F5 to run then it gave me a break point. So i ran it directly from the .exe under the Binaries > Win64 folder and it crashed and gave me a First/Second Chance Not Available error, any ideas?

Did you rebuild ShaderCompilerWorker? As that will most likely cause a crash if you didnt.

Hello,
Explain to "Dummy", how to fix it please!

I'm trying to get UE 4.8 + VXGI. I downloaded from GitHub "UnrealEngine-VXGI.zip" and unzip it.
I launched the "Setup.bat" and got this:

I said, "y" and wait for the end of the process.

Then I run "GenerateProjectFiles.bat" and get this:

Setting up Unreal Engine 4 project files ...
"" C: \ Program Files (x86) \ Microsoft Visual Studio 12.0 \ Common7 \ Tools /../../ VC / bin /x86_amd64/vcvarsx86_amd64.bat "" is not recognized as an internal or external

"msbuild" is not recognized as an internal or external

GenerateProjectFiles ERROR: UnrealBuildTool failed to compile.

Press any key to continue. . .

I installed the program:
Win 7 x64
Visual Studio Community 2013 + update 5
.NET Framework 4.6 and 4.5


What could be the problem?

The first time I work with Visual Studio, and installed it only yesterday. Probably need some additional components?


Is there any other way to get the Unreal Engine + VXGI?

I have had many problems with FLEX and Waveworks working on GalazyMan2015's version.

The Flex test works fine using this version of the engine, but trying to make a fluid emitter in my own VXGI-enabled test level inevitably crashes or only produces fluid-behaving flat checkerboard sprites.

Waveworks doesn't look right at all in the test map. I get some sort of roughly-regular displacement but the foam doesnt move, water is opaque, all wrong.

I'm working on a better Waveworks material right now that I'll share in the next few hours if it gets to a decent place.

Didn't get quite as far as I wanted (and for some reason I can't upload the screen shot) but this is where I got it to: linky

(It's also very much setup for near-shore vistas at the moment, but I think I exposed enough variables to customize it thoroughly. Looks a bit overly metallic if you get in close, currently).

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.

VXGI+OpenGL make me wanting to get hands on it.. even without Unreal integration..
also just a question.. does the OpenGL version similar to D3D11 version run say on modern GL4.4 drivers but on Nvidia Maxwell uses conservative raster NV GL extensions etc.. for faster performance?

hope you can shed light on this..

Also can NVIDIA make some VXGI 1.0 beta release with D3D12 and OpenGL support and post on Gameworks download site (https://developer.nvidia.com/gameworksdownload) just as currently a 0.9 release exits there without Unreal integration..
hopefully the others can also integrate with their engines without more Nvidia work and as said get it earlier without waiting for Nvidia to make a UE integration..
thanks..

[oscarbg]

Just the dumb question of the day are all Gameworks libs VS2015 ready.. I say that because 4.10 will have support for it and all(?) third party deps seems to have VS2015 versions where appropiate.. I even see Physx and APEX VS2015 folder..
so 4.10 will be coming fast and Galaxyman will make a branch of it so NVIDIA be sure to provide VS2015 compiled libs in case current libs aren't compatible.. VXGI, HBO+, FLEX, Hairworks, Waveworks, I'm looking at you..

Yes, the OpenGL version is supposed to work on non-Maxwell GPUs too.

We definitely will update the package on Gameworks website. Need to fix some issues with GL and make DX12 use the Maxwell features (which depends on the driver supporting them, so maybe there'll be a release without them first).

Can't say for all GW, but VXGI is VS 2015 ready. The same .libs can be used by both 2013 and 2015.
