NVIDIA GameWorks Integration

[Chesire]

is there any way the more experienced developers can post an .exe of UE4 with VXGI integrated?
It would certainly save me a lot of time..

It's not very newbie friendly, that, unfortunately, is a given.
You'll just have to bite the bullet. Sooner or later there's going to be an update and there you go again.

1) Get a Github account
2) Install Visual Studio Express
3) Download or clone the latest VXGI build
4) Run setup.bat
5) Run generateprojectfiles.bat
6) Double click UE4.sln
7) Wait eons for it to do it's initial stuff
8) Right click on UE4 in the sollutions explorer and select build
9) Wait eons again
10) Launch UE4 VXGI via F5

I probably forgot some stuff but the above is the gist of it.
Again, yes, it's not as easy as a lazy plugin or anything, but it's better than not using it because you can't follow 10 or so relatively easy -albeit slightly single time consuming- steps.
Just do it ;-)

Iirc it's floating around somewhere on the VXGI Q&A 'forum' on Github.

Hmm, I wonder if it could be partially done from Epic's side, where it bakes whatever lighting method is active.

I'm secretly hoping Epic will re-open the door on SVOGI (and just copy-paste CryEngines' implementation for all I care). What can I say, I'm a braindead optimist

Been getting this error a few times when trying to use the 4.12 build, sometimes with general use, and sometimes like in this case it won't even let me turn the effect on.

Hello,

I want use flexible mesh in game and for this I want use Flex of Nvidia. I has tried to integrate this

in the UE4.10 but This is not the web page.

I need help.

First you need to connect your GitHub account with your Epic account: log in to your Epic/UnrelEngine account on unrealengine.com and connect your GitHub account.
then follow these instructions:

Special instructions for FleX branch:

git clone https://github.com/NvPhysX/UnrealEngine.git

You should now be on the release branch. Run setup.bat. You can now run GenerateProjectFiles.bat, build UE4, run it, etc.

git branch –t FleX origin/FleX

git checkout FleX

GenerateProjectFiles.bat

Open .sln, build UE4.

Run UE4 Editor, open the FleX test project.

I'm not sure if this is related to the shadow issue mentioned by netseeker but I don't seem to be getting any shadows using the 4.12 build.

Maybe I'm missing something obvious. I just have a simple scene with a spotlight, floor plane, a sphere and a cube. VXGI diffuse is enabled. All objects are set to movable. Also, I notice if I untick the "Enable Diffuse Tracing" box there is no noticeable change in the scene.

For the hell of it I built the lighting and get the error "Lighting build failed. Swarm failed to kick off.".

Should I just go back to the previous build then? I followed the steps in "UE4_VXGI_Overview.pdf" as well and everything thing seems in order.

Hi - with slight trepidation i'm going to add another question to the thread.

Has anyone taken a look at nVidia's multi projection stuff. Specifically, i'd like to dynamically change the projection in runtime.

Build Lightmass in Visual Studio, it isn't done automatically.

I would like to see PhysX GPU Rigid Bodies. That would be interesting to have. Although I understand it is only CUDA compatible at the moment. It would open a completely new field of physics games.

Anyone else getting 404 with the links?

The links work, but you need to setup your account details and be signed into the linked GitHub account first. Here's how to do that:

Okay, thanks! I'll try it. Actually I already made an account. But it was still giving me the 404 errors. Maybe just my account wasn't confirmed or something.

Has anyone had any success using VXGI for VR? In my tests I'm getting massive lag, flickering and frame drops in the HMD even though the viewport is getting decent frame rates. It seems like a bug more than pure performance limitations.

Just curious if anyone has any tips for setting up a VXGI project for VR? I'm running the 4.12 build on a 970 and the VIVE HMD.
