Man, you are , I am reading some PDF and slides made by you, they are truly useful!

Ok. I re-downloaded it and it compiled ok. When I run it though I get a new error:

The program can’t start because api-ms-win-core-libraryloader-|1-2-0.dll is missing from your computer, try reinstalling etc…

If I click ok a few times it goes and I get the original shadercompileworker errors that I was getting before. Not sure what’s going on. Any help ?

The same for me,
I have Windows 7 x64
and I have copied “D3Dcompiler_47.dll” under system32 but I have the same errors/behaviour of @Chaosrik

What are the license costs for using GameWorks? Specifically WaveWorks. It is for free to use the WaveWorks SDK with UE4.

i got same problem with @Chaosrik too

Ookay… Microsoft isn’t making it easy. They actually have different versions of d3dcompiler_47, and apparently the newest one requires some system DLLs that are not present on win7.
There is another version of DLL present in the UE distribution, :
Engine\Binaries\ThirdParty\CEF3\Win64\d3dcompiler_47.dll

Please try either a) copying it over to Engine\Binaries\ThirdParty\GameWorks\VXGI; or b) setting r.D3DCompilerPath to point to that DLL. If it works on your systems, I’ll replace the DLL in the repository.

Ok, copying the dll over seems to work now. Thanks a lot for that

Thunderstruck · May 30, 2016, 4:27pm

Works for me too (option a)…
I had copied the other version before.
Thanks

hey ,
can you tell us when flow and GRB will be integrated? thx

Nigkdo · May 31, 2016, 12:08am

Im curious about that too. Especially GRB.

ZAxis · May 31, 2016, 5:15am

Yes.flow and GRB are amazing.i cant wait for their integration with ue4.

The page for nvidia flow, which I had never even managed to find before today, says June 2016 for a flow beta release, and Q3 2016 for UE4 integration.

As soon as I enable Diffuse Tracing anything outside VXGI range lose specularity.

Any ideas?

Edit: Forgot to add, problem happens only if I enter r.VXGI.AmbientOcclusionMode 1 command. Without it, the square isn’t there when I enable Diffuse Tracing.

Edit 2: Removing the directional light narrows the problem down to skylight having no effect outside the vxgi range when vxao is enabled.

Maximum-Dev · June 1, 2016, 5:01pm

image shows that the skylight has no effect outside the VXGI range when VXAO is enabled. Can anyone confirm is a problem with the VXGI 4.12 ?

Repro steps:

Create a landscape (doesn’t need to be huge, just big enough so you’ll have some space to see outside the VXGI range. The image below is a 512x512 meters landscape).
Only add a Skylight and set to movable.
Enable Diffuse Tracing in PPV
Enter r.VXGI.AmbientOcclusionMode 1 to enable VXAO

Confirmed. Also in 4.10
Would be great if could tell us how to circumvent .
@ ?

Not going to lie. release was a little sloppy. Thanks for your hard work but hopefully you can test things out a bit more before you push them to Git.

anonymous_user_7c71c8ec · June 2, 2016, 1:42pm

Fixed it in 4.12, pull the latest from github. Thank you @ for the repro steps.

Chesire · June 2, 2016, 1:46pm

! Many thanks.

Gandosh · June 2, 2016, 4:13pm

! @do you have any plan for AIO version?

mittense · June 2, 2016, 4:22pm

Last I talked with GMan he was pretty buried under work, so I’m not sure how rapidly he’ll be able to attend to his branch.
