Hey ,
I just came across thread the other day and finally am going to be setting some time aside to test out tonight! I didn’t realize GameWorks Integration is already far underway as well as VXGI finally being available in UE4. Right after it was announced, I was dying to try out after it was said to be coming first to UE4. I saw the Nv branch but have been very busy lately and didn’t dig deeper and might’ve lost it seeing VXGI in there. I was so happy to see thread up . Thank you so much for getting going and to all the teams working on the implementation and advancing the tech. Flex is seriously going to unlock a lot of new ideas for more physics based games. I remember Tom Petersen talking about it when the 980 released or more specifically VXGI with Shrout. I’m going to give a shot but seriously, what NVIDIA is doing and it’s commitment to game developers and innovating the space is amazing. I’ve been on the green side of the force since the NV1. I think it came with Daytona USA and like Virtual in some crazy big box when Electronic Boutique wasn’t in GameStop. And the fact you’re ex-Ageia and still rocking hard evolving farther really goes to show how great of a company NVIDIA is. Keep up the great work and thanks for putting in the time to get up and running into 4.7 so the community could access it. Man I’m excited to check out! Thanks again!!! 
EDIT: VXGI now supports more than 1 bounce?! Wow, keeps getting better.
