The branch to look at is DevRendering. It will automatically compiles to 4.26 atm. The Water system is there with some maps, but those are not final yet.
Thank you for the response. I’ve actually already built the 4.26 DevRendering branch and have been running with it but I do not see any actors described in the video nor do I see any plugins included that sounds like it would refer to the water system.
I only started using Unreal this month so there might be something obvious that I am missing.
You didn’t miss anything, the good stuff is just not there yet. During September, when the 1st preview goes live, it will be there, otherwise it could not be called preview
