NVIDIA GameWorks Integration

[Lord-Kvento]

Is there any other way to get the Unreal Engine + VXGI (not use Visual Studio)?

[Squarecoin]

or , do you have a timeframe for any further hairworks updates? If you did I’d really appreciate it. I’ve got comfortable using the current implementation, and now am really hesitant to going back to faking hair strands the old ways, but would love to know if it’s going to be applicable outside of outdoor, directionally lit scenes any time in the medium term.

Ah, UE4 hair…

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

Thanks
Apparently, Visual Studio Community 2013 is not enough…

Should be, since thats exactly what I am using. Express edition isn’t enough as far as I am aware, but community edition does work.

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 :
…
I said, “y” and wait for the end of the process.

's the first thing you did wrong - you need to answer “n” to the question about overwriting files.

@;394841

Then I run “GenerateProjectFiles.bat” and get :

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
command, operable program or batch file.
"msbuild" is not recognized as an internal or external
command, operable program or batch file.

GenerateProjectFiles ERROR: UnrealBuildTool failed to compile.

Press any key to continue. . .

It looks like VS setup didn’t make the right settings. Check out: https://answers.unrealengine/questions/14208/error-compiling-ue4-using-vs2013-ultimate.html
Alternatively, try running GenerateProjectFiles.bat from the VS command prompt (search for it in the Start menu).

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

No, at least not yet. We don’t distribute built binaries.

[Lord-Kvento]

Thank you!
Again, I unzip the file “Unreal Engine-VXGI”, then run Setup.bat and refused to change the file.

I checked the directory VS in “System Variables”, he was right.

I tried to run “GenerateProjectFiles.bat” from the command line VS and now I get :

It appears lacking of a file in the VS. I have tried reinstalling VS (the default installation), it did not help. Maybe somebody knows how to solve?

Hi,

How can i move or rotate flex object ? Because set actor location or rotation not working.

Thanks,

If you have same problem like me use way (actually solution is really bad practice but it works right now ) :

• Select “Attach to rigid” options in static mesh editors flex panel.
• Create little box mesh inside of your soft body and disable visibility.
• And move mesh.

Again, I unzip the file “Unreal Engine-VXGI”

Hi, is a random guess.

Some people have had issues when they git clone a single branch, as opposed to git clone the whole repository then git checkout the (for example) VXGI branch. So if one downloads a single branch as a .zip file, I wonder if occurs too.

In any case, if the is with VS Community 2013, etc., I found AnswerHub, though the solution is not, um… very palatable: https://answers.unrealengine/questions/260186/unrealbuildtool-exception-systemiofilenotfoundexce.html

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

are the corresponding assets:

(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).

Nice

metahost.h is a core Windows SDK file. suggests that there is a problem with your Visual Studio/SDK setup I am guessing.

[theprotonfactor]

Is the Turbulence merge still in the works ?

@;394599

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 am using a 980

@geylangwarrior;396132

Did you try what I said? Official NVIDIA Branch of FLEX and the standalone FLEX demos? My branch should have no issues, in fact I have been using FLEX and VXGI together week without any issues.

Hmm, thanks, the installer didn’t set WindowsSDK_IncludePath, so I had to add to Include Directories manually
Now I get a lot more errors

I’ve tried to reinstall Windows SDK, but still get the same errors

[anonymous_user_bcf66e2c]

There is definately something wrong with your setup. These errors are all specific to the Windows SDK. Unfortunately, besides reinstalling anything, I do not know how to fix them.

[Kalman11]

Maybe I should use newer SDK?
Edit: I needed 8.1 SDK, I had it installed, but some files were installed on D:, I don’t know how (a whole folder named um)
Edit2: I’m so , I could build it just to notice I downloaded the wrong version (not 4.9.1_NVIDIA_Techs, but release branch 4.7.3 without Nvidia Gameworks)
At least I can build it now

[Lord-Kvento]

So, after much torment, I moved forward, but again got some problems.
At the moment, I have successfully completed the file “GenerateProjectFiles.bat” and received “UE4.sln” but when I try to build it, I get the error:

Thanks for the help, the process of building went on, but the error still remains, she just came later.
