NVIDIA GameWorks Integration

I’m hoping that by UE4 v4.15 there will not only be VXGI again, but that also we can have a merged branch of several other Nvidia solutions.

I would like to see in one solution:
VXGI + HBAO+
HFTS/Shadow Library
Nvidia’s Volumetric Lighting

That is my ideal project setup that I would love to work off of. I’d try doing it myself and merging it in but I’m still trying to get a thorough understanding of all the in’s and out’s of UE4.

BTW, definitely check through various console settings with VXGI when using it. For example up until today I was thinking VXGI was too expensive even for an area like “Realistic Rendering”; it turns out I simply hadn’t changed map size to 64 On top of that, 4 cones instead of 8 can really help.

I definitly support idea. HFTS and PCSS have been used in multiple games like The Division and Watch Dogs 2. And volumetric lighting has been integrated in Fallout.
VXGI does a great job making realistic indirect lighting and shadow. However, in UE4, there is no good direct lighting solution to achieve soft cast shadow. CSM just doesn’t have it. I did try the combination of VXGI and distance field soft shadow.
The result was not good and VXGI with distance field shadow appeared more flattened and desaturated. We love to see HFTS and PSCC to to integrated into UE4 since their stablility over traditional CSM.
For volumetric lighting, it definitly is better than faking the effect with a plane in UE4. And if you are to build a dynamic scene, the volumetric lighting will help it greatly.
