I just watched the Nvidia announcement for the Geforce Maxwell series and there was one slide during the PhysX Flex with fluids that mentions coming to UE4 soon. Did I get that right? Can we expect fluids soon?
Hi Ryan,
This has been discussed on the forums before regarding Nvidia’s Flex.
James Golding pointed out that Epic and Nvidia have a great relationship and try to find the best solutions for things like this but ultimately it will come down to if it can be implemented in the engine in a cross-platform way such as Apex Cloth and Destruction.
It is something that may be considered in the future if there is a cross-platform way of getting it into the engine. 
Tim
I HOPE this gets implemented!
