NVIDIA GameWorks Integration

[Number47]

@;242879

Does the Unreal integration for Flex allow developers to get feedback from the simulation(eg. contacts, particle position/velocity etc) as well as modify it(eg. apply forces, create/delete Flex entities etc), as per the functionality exposed in the Flex API?
I’m trying to figure out how to build game-play around Flex with UE4 blueprints, but don’t see how can be accomplished…
Umm, is there actually any documentation regarding usage of Flex within UE4?

If you look in \Flexproject\Documentation there is a tutorial on authoring flex assets in UE4.

If you create something cool, please make a video tutorial.

Cheers

Is anyone else getting a 404 in the Github link?

Is you GitHub account linked and logged in?

Yeah I’m logged in… it even says NvPhysX has no activity, repositories, anything. Weird.

Odd. /NvPhysX/UnrealEngine works fine for me.

Works fine for me as well.

Go to www.unrealengine and sign in, then click on the “Profile” tab. Make sure your GitHub user name is typed into the “GitHub Account Name” box, and it is case sensitive so make sure it is exactly the same, and then hit save.

After that you should be able to access the repo, entering your account into that field enters you into the “Epic Games” organization on GitHub. Hope that helps!

Ahh, yes, that’s what was missing. Thanks for the help!

P.S. I still cannot post new issues in github

It’s broken for me too. I filed a support request with Github.

Hey ,

Hope you had a great GDC. Any word on Flex surface rendering?

Thanks

Still under development, I’m afraid. A few unrelated support issues have taken up some time. Sorry about that.

Github Issues are fixed now! Many thanks to the prompt support at Github! Please feel free to file new issues, and we’ll try to get to them ASAP.

Help! I builded the VXGI branch in Visual Studio with no problems, but when I try to run it, it says that “UE4Editor.exe has triggered a breakpoint” and it will either exit if I try to continue or hold the execution… Any clues on what to do?

Edit: Apparently it says “Ran out of memory allocating 58731628704 bytes with alignment 0”. Is 8GB of RAM not enough to run build?

Look for “ShaderCompilerWorker” in the Visual Studio solution explorer and build it.

Yup, nailed it. Thanks!

So no matter what I do, I cannot build the VXGI branch at all… am I missing something obvious?

I think some files were overwritten by the Setup utility. Did you switch to the VXGI branch before or after running Setup.bat? The way I do is
(1) git clone the default release branch
(2) run setup.bat;
(3) git branch VXGI origin/VXGI
(4) git checkout VXGI
(5) generate project files
(6) build

So, 's what I’ve been doing lately with VXGI. I must say I’m pretty impressed with how much I got with so little tweaking, yet, my input for VXGI is that it still needs to get better documentation and fix some minor issues with the VXGI specularity.

Nice video, thanks for sharing. Could you please be more specific about “…some minor issues with the VXGI specularity.”?

Thanks,

quick question …

can flex handle water drops simulation. like water droplets on windshield. kinda like how driveclub does it?

We haven’t provided the fluid surface rendering solution yet, but once we do, yes, that should work I think. You can adjust viscosity and adhesion, etc.
