I’m not sure if it’s really a bug, maybe it’s something wrong with my project, but could anyone try entering 0 into the number of diffuse cones and see if it crashes? (I’m still using the 4.8 Version by )
I did it by accident and the engine just froze completely, luckily I was doing nothing serious…
Cannot compile newest 4.9 branch (/tree/VXGI-4.9).
Getting like 13 errors, main of which I suspect is
Error 12 error : Failed to produce item: …\Engine\Intermediate\Build\Win64\UE4Editor\Development\UE4Editor-UnrealEd.lib …\Engine\Intermediate\ProjectFiles\ERROR UE4
And it’s not generating Editor executable, which makes sense I guess, provided that it fails to build. I tried the old “copy NVIDIA api files” trick, but no dice.
Please advice. Never ran into with older branches or with 's ones.
Thank you.
Something to note: when launching the editor, it reports version as “4.7.4”.
– EDIT –
Sorry, my mistake. When I cloned the repo, I didn’t realize I had accidentally selected the incorrect one. I’m cloning and compiling the proper one now (/tree/VXGI-4.9). I’ll edit again if the version is still there!

– EDIT 2 –
Just cloned that repo above, and it still has the version listed as 4.7.4 AND I’m not seeing anything related to VXGI or HBAO+. Compiled fine, but the sample maps/projects are not present, and there are no settings anywhere (post processing, lights, materials, etc). Was there a mistake on my end, or was there a mistake with latest repo, and it’s basically just core Epic 4.7.4 UE4?
– /EDIT 2 –
Anyone tested the new 4.9 branch on a 980+ GPU running in yet?
I haven’t upgraded to Win10 yet so i haven’t been able to test it out, was curious as to the performance difference if any in early stage?
Use gits shell. Change dir to where you want the build to live in (e. cd D:).
To clone and select the VXGI-4.9 branch (change that name to whatever branch or tag you want else)
git clone git@github:NvPhysX/UnrealEngine.git -b VXGI-4.9
To change your current clone, change dir to inside where it is (e. cd D:\UnrealEngine) and:
git clean -dfx
git checkout VXGI-4.9
setup
generateprojectfiles

Ugh, yeah- I just came back to do a third edit. I needed more coffee, holy cow… Went through wiping and re-cloning 4 times, took all day, then I walked away and it hit me like a ton of bricks. Might help if I actually checked out! Thanks, haha :rolleyes:
I’ll be testing on Windows 10 with , though I’m only running a 750 Ti. I’ll report my random findings though- it should provide a peek at lower end cards!
The error you pasted is the summary one, it doesn’t describe the. In case a clean/rebuild doesn’t help, please open the output log and find the first one or two lines containing the word “error”.
Is there anything special we need to do to enable HBAO+ with the latest version? I tinkered with the settings in a post-process volume, but I’m not seeing any changes. Normal AO works, but HBAO isn’t working as it did in the previous version.
Compiled VXGI 4.9 branch without any issues, did a test run on the SciFi hallway (just the regular one with VXGI enabled, not the NVIDIA one). Got around 45fps in D3D11 mode, and around 30fps in mode on a NVIDIA Titan X.
Hi ,
I’ve been able to pinpoint what was causing an. 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 showed me, which is setting “Definitions.Add(“WITH_GFSDK_VXGI=1”);” to 0 in *…..\Source\ThirdParty\GameWorks\VXGI\VXGI.Build.cs * 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 hopefully releases his version and give that a try?
Thank you!
hi link /tree/VXGI-4.9 is a official merge for vxgi in ue 4.9??? with new version of vxgi ?? or the vxgi version is the same of ue 4.7 ??
Thats the official NVIDIA 4.9 VXGI branch.
thanks man
Thanks for reporting .
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: (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 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 than on other GPUs, but you don’t have to.
Thanks, ! Everything compiled perfectly with WITH_GFSDK_VXGI=0 time 
Hi there,
Tried building 's “4.8_NVIDIA_Techs”, but encountered the following errors:

Can anyone shed some light ?
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.
