I’m not actively looking into porting any other GameWorks techs into my 4.20 merge. I looked at VXGI and HairWorks briefly but both contained some changes that would have taken me long time to fix. These both are also probably least useful in actual game development (they are cool for tech demos), VXGI 2 specifically requires + GPU which is a huge limitation for the tech itself. As far as I know, all the techs in my current 4.20-GameWorks branch work with AMD as well.
That being said, I’ll probably still add these if Nvidia pushes 4.20 versions into their github repos, just not going to put my own time into porting them.
