Great tutorial using UE5.0. Had to import UE5.0 scene into UE5.2 for the "WaterBodyCollision" to appear in the Ocean. For the second method, the WPO for the materials only worked in 5.0. Thanks for the awesome videos!!

[@plagiats]

Wow dude you blew my mind with the material approach. Very detailed, full of useful information... I mean THANK YOU, it's a very good tutorial. Learned a lot. Subscribed!

Thank you Phillippe!

[@magnetvideogame]

Thank you!! I nearly gave up on implementing something like this in my game but this made everything so much easier.

Doesn't work for me in UE5.1. Object just falls on the "floor"

[@akshayak9461]

Got the same issue...have you found any solution. If, plz do share the solution.

[@AndyIstomin]

@akshayak9461 it's a 5.1 bug. I desided to use waterline plugin for my project. But I google a lot. And there's 2 way you can fix it. You can use UE 5.0 set up everything and then open project with ue 5.1 (I don't know if it works with 5.2 and 5.3) Or you need to add some files to you project to make everything work (I don't remember it was 6 month ago - google better😀)

The material approach no longer works in UE5.1. Anybody know any workaround?

[@roher86]

Ok, so... When you use the Instance Material and choose either "normal" or "cloth" option it appears some parameters to set. I enabled the "UseFixedWaterDepth" parameter and then I wrote the depth it was set in the water element i was using. This worked for me. Hope It'll work for you too. :)

Dear Klaus! Great tutorial, thank you. It works very well for static meshes. But when i try to make a skeleton float (with physics enabled, for ragdoll physics) it doesn´t work. There is said that there is a collision problem.... any ideas?

[@ПРОСМЕЛЫХИБОЛЬШИХЛЮДЕЙ]

Hello, thank you for the video. I was able to get this working with a static mesh version of my boat. But i have created an animation of a paddle wheel turning on the back, now i have a skeletal mesh instead and I cant add sprockets. I have no idea how to get the buoyancy to work now. Any help would be appreciated

[@kirkr]

Great tutorial!

[@fbbk3]

hi, thanks for the great tutorial. i got the first method using pontoons to work, but the second method (material magic) does not work for me. the blueprint graph looks exactly the same as yours but when I apply the material to my plants and enable physics and gravity, they just immediately sink. the same thing happens when i try the material method on a cube or sphere. i tried playing around with the mass value and set it to something very low like 0.0001 like some comments suggested, but it has no effect, everything just immediately sinks when i try the material method :( please help

[@hrleinad]

The material doesn't work in 5.3; WPO does nothing to the object; it's like it's broken or something.

[@godfreyalina]

I was running into this as well in 5.3. If you haven't already, try plugging a Static Bool set to False into the Use Depth Attenuation slot on Compute Gerstner Waves node. That fixed it for me.

[@hrleinad]

@@godfreyalina oh, I will try that. I know my comment was 3 months ago, but thank you very much for that.

[@DynamicalisBlue]

I can't seem to get the material method working unless Depth Attentuation is disabled, but doing so greatly limits what I can do with it. I am trying to use it with an ocean, anyone know why this may be happening?

[@peterjohnson8570]

In the first example, I noticed you gave the boat, as a whole, a mass of 100kg... is there a way to distribute the weight? I imagine it's difficult to get a very realistic simulation without it... For instance, even a static asset like a small dinghy going over a wave might be back heavy and land differently than if it were front heavy. Similarly, you could imagine a player standing on the side of a canoe or something, the weight of the player might be expected to dynamically effect the canoe and cause it to capsize.

[@jeuxdz]

can u make a tutorial on how to move the boat ?

[@kooshypir]

Thank you for this tutorial! Is there a setting for the water body? I followed all your steps but the boat keeps falling through. Any help would be greatly appreciated!!

[@FhayAlonso]

"When I try to create the material, as soon as I connect the bool parameter to the switch, Unreal Engine crashes. Has anyone been able to solve that? I'm using version 5.2 of Unreal."

[@solaries8185]

How do you place the water on a level? I've looked at every water video I've found and they ALL start with the level already there with all the water properly set up already and NO video says how the water got there.

[@ivanchaves3787]

Maybe it is a little late, but there is a plugin called "Water" in UE5, you activated it and you can place actors like Water Body Lake, Water Body Ocean, etc.

[@parthchotaliya3468]

[@roher86]

P.D. Also, you need to select Gerstner Water Waves in the Water body details panel under Waves Source.

[@WPguru]

Same here, in 5.1.1 the boat just sinks to the ground no matter how many pontoons and regardless of weight. 🥺

[@marioperez1720]

Hello, I need your help, in the view port everything works fine, but when I create a sequence level and render, the objects that should float do not move. Thanks

[@Native_Creation]

The editor is real time, you need to add your objects to Sequencer in order to see it rendered, not sure how that works with these techniques though.

[@meidan3819]

Great tutorial though!, but i didn't quite figuring out how you implemented the material function to your foliage from Megascans since, it has already a materials that are conected to the World Position offset. .6:02 ,11:50

[@CrowBiomes]

If WPO already has something connected to it then add it to the final result

[@meidan3819]

@@CrowBiomes First of all really thank you for answering!.I think I'm kind of understand what you're saying. after some a while i found a some sort of solution,because this specified Megascans foliage has nodes that menat for wind displacement and they took the place of the WPO. I don't need them for this case and i can just replace them instead with that function.

Awesome tutorial! What pack contains the boat mesh?

[@shikainokageyoshi]

Great tutorial, thank you but i have question; I made a small boat, tried it with the same logic. The boat bounces and somersaults on the water. Any idea how to fix this issue?

[@CrowBiomes]

You'd need to adjust Pontoon location to balance the buoyant force.

[@shikainokageyoshi]

@@CrowBiomes It worked, thank you!

[@lonelysorrowknight]

Does this only work for landscape water? How can I achieve this with an indoor body of water? Like a pool or something.

[@CrowBiomes]

If you are not using water system then you have to create your own buoyancy. Add a force opposite to water when the object is touching the water plane.

[@jimishatk9982]

Hi, I tried this but I faced an issue. When I'm trying to float the object it's not even sinking, I enabled simulate physics. But it's still the same. Is there any change I have to make in water details also, plz reply

[@Manim8]

Did you make sure your boat was the scene root in your BP?

[@Badwolf2743]

I was wondering how it would be possible to create buoyancy for an object in still water that does not have waves that is a flat plain. The issue I've come across is I don't want to make a timeline and animate the buoyancy as I have a blueprint where the water level changes when a button is pushed and I want objects to move with it while having buoyancy even if the water is a flat plain. Not sure how to do this though.

[@CrowBiomes]

You can apply a upward force on the object after checking whether it's overlapping with the water or not. So when the water level goes down, It will fall down until it overlaps and a upward force is again applied. Applying force on different places on objects would make multiple pontoons.

[@Badwolf2743]

@@CrowBiomes Ok thank you for your help, much appreciated.

[@jamesonvparker]

Is it possible to make the character float down a current?

[@CrowBiomes]

It has buoyancy component and the river tells you direction and speed so Yes

[@troncau8433]

Been trying to get this working for a while now. Running UE5.1 water plugin, all the settings are identical to yours. My boat just spins uncontrollably nose down and sinks below the water. I have the BP_TestBoat above the level of the water. If I modify the Buoyancy Coefficient it'll propel into space! Has anyone got this to work on UE5.1?

[@CrowBiomes]

It looks like the pontoons need to be adjusted. They apply force to your object. If they are not applying the same moment, the object will spin. (Imagine pushing a pen with the same force from both ends but you push it a little closer on one side..It'll spin) Make sure they are applying the force on the same symmetric point.

[@troncau8433]

@@CrowBiomes Thanks for replying Klaus. The pontoons are in the exact same coordinates of the coastguard ship that yours are. I've tried modifying the pontoons, every possible way. I've spread them out/moved them in. Added more added fewer. I used the BP_BuoyancyExample (located in plugin content) and it works fine. I've tried different static meshes. I've found the more uneven the bottom collision is the greater the distortion. I've uploaded some screenshots. drive.google.com/drive/folders/1K3PEVs3tgFOoA0IEKcMH2t5CY9dUy_JM?usp=sharing
