NVIDIA GameWorks Integration

[KillingWord]

thank you for clearing this up.

i tried chesires console command and it works great.
the look is fantastic.

are there any values one could tweak?

[Aabs Inc.]

Yes, that's true. Not all GameWorks, just some libraries though.
Here's the official press release: http://nvidianews.nvidia.com/news/nv...eworks-sdk-3-1

Page not found. Or it's just for me?

Make sure your logged into github is all I can think of, as it works fine for me.

Strange. I have a github account and I can download/compile any other UE4 fork, including one from your signature. But page with volumetric lighting doesn't exist for me. Can anyone else confirm this?

Yea this is pretty much the same situation I'm in.

It seems we should have a permissions from nvidia.. https://developer.nvidia.com/gameworks-source-github . Will try

Edit. I got an email from nvidia, joined GameWorks and everything works now.

Thanks [MENTION=56055]Yura_s[/MENTION] I didn't know that you have to join their organisation too.

Hi.

When i enable VXAO by writing r.VXGI.AmbientOcclusionMode=1 in the consoleVariables.ini the GI from VXGI disappear after i re start UE4 and the whole scene is black now...?, so, does VXAO does not work together with VXGI Diffuse Tracing or do i have to configure the settings in other way?

Thanks

VXAO is already included in VXGI. If you change the Ambient Occlusion Mode you simply disable the GI part so you only get the AO part of VXGI (at least from what I've seen, correct me if I'm wrong). So if you want VXAO and VXGI you don't need to change anything and just enable DiffuseTracing and that's it.

It's weird because when I disable UE4's SSAO, I don't get any other sort of AO.
r.VXGI.AmbientOcclusionMode=1 does show the AO pretty well but when I set it back to 0 I don't get to see any AO in the full shading mode.

1) If you end up with a black scene upon enabling VXAO, make sure you have a active Skylight in your scene (it helps, if not for initial check if all works only)
2) If you want VXAO as your default mode, you have to add the cvar to the engine' ConsoleVariables.ini located in X:\YourVXGIbuild\Engine\Config folder.
3) You can isolate AO only by checking 'Ambient Occlusion' as buffer visualization (located in menu where it normally says 'Lit'
4) Works together with SSAO and HBAO+
5) Diffuse tracing should still be enabled. Things like VXGI range etc. still matter since your scene will still need to be voxelized.
6) Tweak VXAO via the 'Ambient' section located between Diffuse and Specular
7) Test with setting Diffuse Color to anything but the default black.

Results -if setup properly- should be very good AO.
It's also much faster than full VXGI.

Hope that helps!

Below is Directional light with VXGI active. UE4 SSAO intensity set to 0.



Below is r.VXGI.AmbientOcclusionMode 1



Below is AO viz:



So no VXAO...

(Sky light didn't do anything to AO) (VXGI settings are all defaults)

thank god, i was going crazy yesterday.

i had a couple of scenes setup nicely and seemed to get VXAO pass to work for a minute but when i reopened the projects, shadows are pitch black.

also turning AOmode on and off would mess up my VXGI in a very random way. hope someone knows what is really going on.
is what emanuel said is correct?
