Hi Alexey,

I've been able to pinpoint what was causing an issue. I do not need VXGI, only HBAO in my project, but when VXGI is present, the shader compilation is getting really slow (like it's almost unusable in production). Thus, I have successfully used a trick that GalaxyMan showed me, which is setting "Definitions.Add("WITH_GFSDK_VXGI=1");" to 0 in ..\..\Source\ThirdParty\GameWorks\VXGI\VXGI.Build.cs This has worked great in 4.8 version, but if I do it in the newest 4.9, it results in those errors I was getting, and the engine is not built.

So the question - is there any way to work around the problem? Or do I just have to stick with 4.8 til GalaxyMan hopefully releases his version and give that a try?

Thank you!

Thanks for reporting this.
The problem is that I forgot to add some #if-s, and certain pieces of code still referenced VXGI when you disable it.
The fix is easy: https://github.com/apanteleev/Unreal...7f921d79ec1811 (you can switch to my VXGI-4.9 branch to get updates quickly, or apply the patch manually to your working copy).

Moved the infiltrator scene to VXGi , removed most of the lights near emissive surfaces , Was getting about 40 fps with a Titan X@1240Mhz , Rendered this video using the Movie Output of matinee , Ignore the animations I kinda screwed it up somehow didnt care to fix because it was 4 AM when I did it.

hi everyone, i have a geforce gtx 970, so i have to check a Vxgi Coverage Supersampling in material for all material ????

No. You can check it for small objects' materials, and it works faster on Maxwell than on other GPUs, but you don't have to.

Thanks, Alexey! Everything compiled perfectly with WITH_GFSDK_VXGI=0 this time

Hi there,

Tried building GalaxyMan's "4.8_NVIDIA_Techs", but encountered the following errors:

Can anyone shed some light here?
Btw I'm using Visual Studio Pro 2013 running on Windows 10.

Thanks!

Make sure to select 'N' when running setup.bat when it prompts you to overwrite files, as it will revert a number of files required by VXGI.

Hi GalaxyMan,

Thanks, that solved it :-)

Looks pretty good. Would've appreciated an epilepsy warning though - it gets pretty crazy once the air-robot starts shooting. I assume thats VXGI having a bad time? My retinas still sting ha.

Sorry for the tangent guys. GalaxyMan, does your latest build for 4.9.1 also include WaveWorks, Flex etc? I noticed you had a build for 4.8 that had a lot of the Gameworks stuff in it, and you'd mentioned you were going to add WaveWorks if you could.

Setting up a project that I'd like to use WaveWorks in. Currently I'm using the Launcher version of 4.9.1 which addresses some landscape issues, but I'd be happy to compile if I could get access to WaveWorks.

If it's not in this branch, what is the latest build that supports WaveWorks?

Thanks so much for this, it's great!!

hey galaxy man have you tried getting flex 0.9.0 into VXGI for 4.9.1 ? I have tried it myself but am getting errors so I gave up. Hairworks was integrated easily just trying to get VXGI but figured I would leave that to the professionals.

[GalaxyMan2015]

I havent tried myself yet, planning on giving it a go over the weekend, I have the VXGI 4.9 branch as my base, I will merge all the others into this one, so hopefully by Sunday I will have something to show.
