NVIDIA GameWorks Integration

Hi all!

https://github.com/Sevenplex/UnrealEngine/tree/4.19-HairWorks



Many thanks Xu Nie (niexuchina) for the hint UpdateBounds() in HairWorksComponent.

Excuse for impudence, and long still to wait for GamerWorks?

Who started transfer GameWorks to 4.19?

hi guys any update from gdc 2018 for vxgi? any video? rtx great tech but (4x titanV over priced for me lol) we can use vxgi still on 970 gtx like old GPU's limit mapsize at 32-64.

i got some tests and package link in youtube. https://www.youtube.com/watch?v=Ts76Y_828Hk

please get this integrated as soon as possible

It's for NVIDIA Volta Card

But i will try if i can

I think you might have to be patient, that one's not even released yet. ( And probably won't be until after Nvidia's Volta GPUs are out on market, since it's designed primarily for those.)



There is one thing I'm curious about. Most of the interest here is on the gameworks things in general, but I'm curious about their VRWorks.
I used the Multires-shading previously when that was standalone, but does anyone here have experience with using their newer VRWorks-Graphics bundle?

I'm curious how many features are enabled in the unreal build, and also very curious if stuff like multi-res-shading nowadays is compatible with forwards rendering as well.

This will be interesting! Let's hope that with the recent focus on optimization, VXGI is finally a practical solution.

Finally i built UE4 after compiling it on Visual Studio 2015 community. But couple of things i am confused! Can someone help me on this. after compilation the UE4 editor automatically opens when i do debugging. well but my problem is that how should i run that same project next time without running Visual Studio.

2nd problem where can i get asset for fluid. to create water.

Hi! guys.

I tested ue4 project made by VXGI-4.18 branch version in https://github.com/NvPhysX/UnrealEngine.

I met error! I don't know why occured error. help me please.

It's executed by ue4 4.18.3 original version.

I think the problem isn't that specular tracing is on, it's that the entire mesh is ignored when only one material slot is translucent.

In the third picture here: https://forums.unrealengine.com/comm...ration/page287 the Opaque material slots are recognized by VXGI, but one material slot (the top of the table) is ignored. That's the "correct" behavior I would expect.

In the second picture, the WHOLE mesh is ignored, even though only one material slot should be ignored. Both pictures have specular tracing enabled. And the Opaque materials are identical in both pictures.

The reflection in the second picture should look like the reflection in the third picture, but it's not. This seems like a bug or at least unexpected behavior. I was wondering if it's user error, like maybe there are some material settings or VXGI settings that would make it behave "correctly"?

[WindyStrife]

Any luck figuring out if this can be fixed? I was hoping it could be done with material or VXGI settings, but no luck so far...

@DsyD:
i cheked it, man
you need disable in Post Process Volume "Enable Specular Tracing"
OR you if you need you VXGI Specular with SSR(screen space reflections), use console command: "r.VXGI.CombineSpecularWithSSR 1"

[DsyD]

Can you send my sample project may be i can help you
