It’s something that’s been on the grapevine for a while now, and it was already (behind closed doors) hinted about at siggraph, they simply didn’t have the nodes ready to demo them.
It’s got little to do with realflow, as they are different approaches, but the most exciting thing afaic is that it should be provided as ice nodes, which potentially means being able to provide fluid solving for a number of things, potentially strands and meshes as well.
The solution itself is very well tested and solid, it’s been used in frantic for a while and it’s been put through some tough productions.
Good times ahead.
