I noticed that Nvidia pushed 4.18 and 4.19 versions of Volumetric Lighting into github:
https://github/NvPhysX/UnrealEng…cLighting-4.18
https://github/NvPhysX/UnrealEng…cLighting-4.19
I’ve merged Nvidia’s 4.19 VL into:
)
Now repo contains Blast + Flow + HairWorks 1.4 + HBAO+ 4 + TXAA 3 + Volumetric Lighting + VXGI 2. I’ve removed the previous additional 4.19 merge with VL (from 4.17) as it’s pointless to keep two identical branches up-to-date.
There were some fixes for TXAA after that date so you might want to try newer version. Also note the mention above, if you need to update, use the 4.19-GameWorks branch instead as it contains now the same tech as old -VL branch.
