I made a performance experiment with VXGI for open world. (with performance tweaks such as map size X, Y, Z 64) And the results on GTX 980Ti & i7 5930K. 4x4 level with average tree density. ATTENTION! AFTER THE UPDATE DIRECTIONAL LIGHT VXGI PERFORMANCE HAS BEEN FIXED. FPS INCREASED TO 80 FROM 48.5. ---

Those can be used for VXAO or VXAL. - VXAO is, in a way, a by-product of the diffuse illumination pass. So, if you enable VXGI Diffuse, VXAO comes in for free (if enabled). - Most PPV settings in the VXGI Diffuse group also affect VXAO, because it’s the same rendering pass. ---

I’m still waiting official Flex integration to drop myself. It’s not difficult to merge the old version, it’s just bit pointless if Nvidia is releasing improved Flex 1.2 soon for UE4 (which I hope they do as Flex 1.2 SDK itself has been out for two month or so). No official word if they are doing however. ---

Meanwhile, they did finally put 4.19 Blast into their NvPhysX repo: /tree/Blast-4.19 I’ve included the latest fixes from that and other nvidia tech branches on my 4.19 merges so they should all be up-to-date. ---

Hello, I want to use some plug-ins in the 4.19 Gmaeworks version you compiled, such as Substance and Datasmith, but the Substance copy has been packaged in the past to open the plug-in prompt error, and Datasmith can’t find the way to use it. Is there a way to use these plug-ins? These plug-ins are very important to me, and the unreal engine that uses Gameworks can be very cumbersome if it can not be used. ---

You can just move the Substance plugin from marketplace folder (from stock 4.19) into your UE4 projects Plugins folder, make sure you have c++ project and then regenerate the project files from .uproject. will generate a visual studio solution which lets you compile substance for the engine version you are using for the project. I will not add substance plugin in my own merged repo as it breaks UE4 EULA, while it’s a free plugin UE4 marketplace, it’s license doesn’t give me rights to redistribute the source code so I can’t do it myself. ---
