Fluid Flux in Action & Tutorial (Simulated Water Physics) UE5.1 Unreal Engine

[ImaginaryBlend]

Thank you for the tutorial! Those spike-shaped bugs are showing there because the generated ground map is corrupted (you can see some red edges on the heightmap debug) and the high slopes inside of those holes are a bit problematic for the shallow water simulation. Usually, I recommend an increasing height of the simulation area (avoid holes in the ground), and increasing slope, damping, and friction values in simulation in this case. New versions will be more resistant to this kind of bugs.

those artifacts are because your fluid emitter is higher or outside of the boundry box that is supposed to contain the fluid.

My guess is that the water spikes occur when water is pushed up the terrain and hits the ceiling of simulation boundary. Extending simulation boundary upwards may help. This seems to be consistent with increased number of spikes you got when you tried to solve the problem by moving volume down :)

I believe resolution is what determined quality/performance balance. Size of wolume in the world should not have direct performance effect, but indirect effect is that bigger volume encapsulates more colliders from your scene and therefore increases performance cost.

It's a very nice plugin, but really needs waterfall speed adjustment - it seems like gravity is doubled in the simulation ;)

We need a kayaking / river rafting simulator ASAP!

The spikes are actually from splashes above your simulation line. If you raised your box up a bit to cover those pieces of land that are sticking up, the water will still simulate properly but will not "leak" out those "holes" where the actor is not covering. Hope this makes sense to you. The Red indicates a "leakin" spot. This will only happen if your water sim splashes above those lines or you move the water to flow through those lines.

still needs water impact phisics for when it hits rock, and the way water evoporates when it has a long distance drop, or too thin of a water source( that evaporates too ).
also drawing on the map directly the borders and path of the water on that creek should be an option, in case you wanna go for something less realistic.

Considering water fluid motion and collision physics is the most difficult to produce ❤❤❤❤

My graphic card melt only watching this video so. Cool !

Thanks for the good lesson. Have you tried using this plugin to swing a boat on ocean waves. I've spent a lot of time. But my boat is constantly either sinking or jumping on the surface of the ocean like a ball and then after a short time it flies away in an unknown direction like a football. Could you write down a lesson on how to make a floating object on ocean waves, so that it would swing in time with the waves, while not flying anywhere and jumping on the surface of the ocean?

Wondering if you know which settings should I adjust to enable water flow underneath my bridge? The debug mesh currently blocks the water at the bridge's start and end, preventing it from flowing through.

Thnks for your tutorial. But when I used Fluid Flux. My Debug surface was on top of the cube, not like you when the debug was in the bottom. My Fluid Flux cant capture the ground or any mesh also. Help me solve this. I use Fluid Flux 2 and UE5.4

@Werewolven is it possible to have the fluid go through a Pipe, that has been blended in blender??

Does fluid flux work with voxel plugin 2.0? Could this be the water we need for a smooth minecraft?

Hi
I’m having funny issue!!
I don’t know how to capture specific time of the simulation!
I’m making a short cinematic film!
If you can!
Thank you!!

What would be the Level sequence settings?
What I’m getting is empty space

[ibrahimakca]

flux simulation has an internal and external area, when I want to enlarge the internal area, it grows in the external area, and I can't, is it possible to adjust the internal area and the external area to the same setting, please help

[Enderking]

This is just so amazing, it’s a shame it’s 360 dollars

[UEnb]

my blueprint says "bad" why is that? :/ i tried on 5.1 but also 5.2

[UnchartedWorlds]

that waterfall looks so amazing, is this somehow with the latest update announced by the creator just yesterday or old version?

[fxbaba]

Pl can you make video on how to render it

[PLlr]

Which rig do you have mate? I looks awesome!!!
