UE5 Fluid Flux II - Water physics simulation in Unreal Engine 5

That looks amazing.

Shame about the commentary :p

I didnt watch it, got annoyed with commentary after 10 seconds and search for it on Google to play myself :D
There are good UE5 tutorials though but I havent installed any of that, just the demo
 
Very impressive, the fact that the CPU is basically idling throughout shows just how much physics the GPU can do when taking care of water on this sort of scale, enable the beach map and you get a much better idea of how it would look in a game. Only 10% of a 12700KF being used means there's loads of CPU headroom to do AI etc for the NPCs
Also ducking the camera under the water shows just how the water is being calculated, it's actually roiling just like how underwater currents would, actual proper physics :cool:

It's a GPU simulation running in an otherwise completely static gym level, not a huge surprise it's not using any CPU time.

Might be a bit stuck if you want to use the GPU to render anything other than some pretty physics!

It would be interesting to know if this sort of thing could be used to simulate real (or as close as possible) real life waves and/or weather.

I watched an interesting documentary on the US navy and a vast indoor pool they use for simulating waves for scaled down ships and submarines. The wave machines and pool must cost a fortune and guess they're only used because computer water physics is no where near accurate for testing multi million dollar boats/warships/subs. They did have all the data from the pool and wave machines fed into computers and controlled it all with computers, but the pool, water, waves and wave machines were all real and mechanical machinery.
 
I installed it on Steam Deck, works quite well (making a vid)
Interestingly part of the install required C++ for the UE4 prerequisites (x64) I wonder if this is UE4 engine or UE5
