Is it possible to combine multiple Github builds of UE4? Example being Nvidia’s Waveworks build + Nvidia’s Hairworks
Not easily, especially considering they are also different versions of the engine. However, I have already done this for everyone. You can grab my version of the engine for 4.9.1 that contains VXGI+HBAO+HairWorks+WaveWorks+FLEX from here: NVIDIA GameWorks Integration - Asset Creation - Epic Developer Community Forums
That is beyond awesome!!! Thanks so much! All I do is download, compile, open?
Follow the instructions on the link and you should be fine.
