Unreal Engine 5 Tutorial - Niagara Fluids & Intro To FLIP Fluids/3D Water & Foam

[@Seeks__]

You have no idea how annoying it is when you go to find solutions and they are paywalled. Thank you so much for your open contribution, I am very grateful for YOU! ❤❤

[@laurofernandes9350]

You r just aweso....i was litterly noob in tNice tutorials...u explained it very simply...thanks i will surely go for next parts of tNice tutorials video.. thanks

[@saqibali-ku4hr]

This video is amazing. I just found out about you last night and already watched all your videos. Your hilarious.

[@cafesamkok7973]

I paused as you went along and did the steps myself and that helped a TON.

[@tondann]

Hey man, please continue that series with Niagara Fluids, maybe with the water shader? I tried fiddling with it a bit to be photorealistic with refraction and no blue tint and it looks decent, but I don't understand the shader of it really. Would love a tutorial from you!

[@tondann]

maybe also go into detail about the settings in the emitter? that would be lovely

[@phil5181]

Please this!!

[@thefloydian1876]

Yes please

[@renderbucket]

Just posting this for anyone else wondering the same thing. Thanks for the suggestion/request Anton Dann. kzbin.info/www/bejne/n3nbf4R7btOSfdk

TNice tutorials is much more simple than I thought with you explaining it. Currently half way through and I feel like I know everytNice tutorialng already lmao

[@StogerStudios]

Hey, thanks for this tutorial! I am at minute 15, and there is no option for spawn rate in the emitter summary of the secondary (foam) emitter. Any ideas on why this might be?

Someone told me that i can use FLIP in blender. Now I'm glad that i can use FLIP in Unreal Engine. The patience is KEY!😂

[@metatrox]

Yes excellent Tutorial. Please more details on the final sim you showed

[@chriszandler3643]

Happy to have found this. Niagara is something I was struggling with, but following along here has helped clarify a lot of things. Subscribed and will definitely watch more of what you continue to put out.

This was really great! Very easy to follow and pleasant voice :)

[@peterallely5417]

Great tutorial thanks so much. I think there are a load of people pining for an accurate beach simulation with crashing waves on the shore. Not so much for real-time but for rendering out cinematics. Would you be up for something like that? Thanks for the great content!

[@AlbowaSinema]

I am with you here.

[@Chrononauts]

Really helpful video! Liked and Subscribed. I have an issue, for some reason when i click Emitter Summary i dont get the same options like you for the foam, so i end up with almost no foam. Any suggestions?

[@lotosjonas2532]

A perfectly made tutorial.

Great tutorial! Super easy to understand!

[@ibrahimakca8628]

oh nice🤩

Yeah I have the same issue 😞

[@UnrealArtist]

Nice tutorial bro, keep it up :)

[@aiartbx]

People getting hyped over fluid flux plugin but wow this is the real stuff.

[@Haganeren]

I really don't understand why for the foam part of the tutorial i don't have the "spawn rate" in Emitter Summary. Couldn't even find it at the customisation of Entity Summary ( no idea how it works though ). Maybe it's different in 5.3 ?

[@paulareb2074]

Awesome tutorial, thank you so much! I love how you explain everything!! Quick question, do you know if is it posible to change the box shape of the pool for an specific static mesh? I can't figure it out!!

[@shadowgames50]

You think it would be possible to make the bounding box follow the shape of an ocean plane?

[@jerichocarter9147]

This was very helpful, however, my issue is when I drop it into my level using landscapes it will not render. The icon appears and I can edit it but no FX.

Hello im just followed your tutorial just now. but i can't find some 'Spawn rate' in my selection category for velocity... it's in secondary_emitter in you video but i cant find this for my category. My UE version is 5.1 can you help me this ?

[@Jacoby_lel]

They restructured some stuff. Unfold the Secondary_emitter windows so you see everything. Then click on "Grid 3D Secondary Emission Points" its in the Category: "Find Secondary Emission Points". There are your Velocity and Vorticity parameters

Please make a tutorial replicating the sample that you used as an example in the start of the video, using megascan assets together with the water effects etc.

[@Chrononauts]

When i use collider with megascan asset doesn't work, only with the sphere

[@ntjson]

Excellent video. Do you have any recommendations on how to have the collider mesh influenced by the Niagara particles, say have the collider mesh float and have buoyancy?

[@LeoGB]

Trying to achieve basically just a hose rather than having a pre-existing pool. If I have the Grid 3D FLIP Hose template, and set the Water Height to 0, in the viewport of the Niagara system this looks like I want it - it constantly emits the particles, and slowly fills the boundary. However when I put this in my Scene and play it, the entire boundary is filled up by default. Can't seem to change this, any advice?

[@LeoGB]

I got it... I needed to change the "Water Height" parameter to be below the Z level my simulation was at... I had been assuming the "Water Height" was relative to the boundary box, but after hours of hair-pulling, would seem it's relative to the world. I just happened to be working at Z:-16000, so it took ages to notice this.

what if i wanted to make another static mesh interact with the water ?

[@jj7pupu641]

Hello, first of all thanks for this awesome tutorial, everything went well on my laptop except that when I put the niagara into my scene, the water looks black and I can't assign any material to it, is there any solution? thanks so much

[@kakamax0192]

Collisons only work with the basic shapes. When I import my own static mesh the collison dosent work even though i added the "collider" tag. Anyone know why?

[@nonenone2748]

Cool! - Can i use niagara emmiter as a light? - As if every niagara particle can lightens room? In order to get dynamic illumination - for example animated-torch-flame illumination

[@renderbucket]

If your using Unreal 5+ with Lumen, Lumen will automatically create light bounce from surfaces that have emissive or very bright values so yes you will get illumination from it. However adding additional lights parented to the objects can help give more practical/stronger lighting and the Lumen GI from the surface can add some more subtle bounce.

[@nelsonpainco1368]

can i use something like that to generate a foam trail for a boat? or would this be too much overkill? i dont need it to be realtime, but to include in cinematics

[@Samanier]

is it possible to make it collide with another emiiter? like inside niagara

[@3dchick]

Omg, you made this not scary--thank you!!!

[@jeremyzapsmash]

before I start this, is this easy or hard? like can a beginner do this well or do I need other experience first?

[@techno2776]

Hello, what to do if the Plugin not works? After activating the plugin and opening the FXS_Pool there is no water and the "Compile"-field is yellow. It says "unknow status; should recompile" when moving mouse cursor over the field. Full rebuild makes no difference and deactivate/activate plugin also makes no changes.

[@renderbucket]

Id reccomend re-installing a version of Unreal. If files get corrupt or messed up that may be the best way. You can also try loading the Unreal Launcher and when you go to Launch Unreal. Instead click on the drop down arrow to the right of the launch button and click Verify. This will check Unreal's files for corruption or missing resources.

[@techno2776]

@@renderbucket Thank You! I tried it but "verifiy" is gray. Also tried another project. When I look from the launcher into the plugins there is no niagara shown. But niagara-fluid is in the engine folder. My version is 5.0.1 and I don't see where I can upgrade. Do I need 5.0.2 to run the PI?

[@renderbucket]

@@techno2776 oh that makes it pretty clear. Try this, in the Unreal Engine Launcher where you launch Unreal, at the top you should see the text ENGINE VERSIONS and next to that you should see a + sign . Click on that + and it will add a greyed out Unreal version . Click the down arrow on the Version Number select 5.0.3 and install it (click install button). 5.0.3 is the version I used in these videos but anything 5+ I think should work.

[@renderbucket]

And if Verify is Greyed out it may mean the version is not installed or still downloading.

[@techno2776]

@@renderbucket It's not working😪 The "+" next to engine-versions is gray and I cannot press it. There is no way to install the ltest UE5-version from my launcher. I found out that I can choose other Niagara-Systems. "Grid 2D Gas Explosion" is working. And the funniest thing: Even both others of "3D Liquid" (Flip House, Flip Splash) are working. Only 3D Flip Pool is not able to compile. It's yellow from the beginning in all projects and water is not shown. Very funny.

Can I make my player interact with the fluid ?

[@Grace111419]

super helpfull ty!!

[@Oceana_3D]

Hi, Is there a project file we can buy?

[@aweidenhammer]

Is there any way to bake these sims so we can do larger ones that play back at reasonable frame rates?

[@renderbucket]

Kind of, you can cache them out like this. kzbin.info/www/bejne/iILYqoWKh7aabdU But its not going to play that much faster, the slowness on large sims is mainly due to also the amount of data it has to load per frame.

[@aweidenhammer]

@@renderbucket Thanks! Not speed I'm looking for, just larger sims for cinematic stuff. But I would probably still use flip fluids in another DCC for most things.

[@MarvelMaster]

WTF how did I miss this

[@renderbucket]

Thanks for watching! Feel free to let others know about my videos and tell me what you would like to see next. Im basing videos solely on request/demand.

[@TheDonkerZ]

Hey there. Great video on the basics of the FLIP system in UE5! I was wondering if you had any experience with the new Grid3D fluids and complex collision? My hunch is that these systems do not interact with any sort of complex collision, but I might be missing something I could be playing with inside the emitter. Would you happen to have any ideas on if complex collision would work with these systems?

[@xaviduch]

Hey! I am a rookie but...I can't understand why I can't compile after creating the FSX_Pool...when I do it, I get a warnig yellow interrogation on "compile! and a debug that says "the mesh distance field generation is currently not enabled, please check the project settings". I check it, and I enabled the only "distance fields" search I found: ENGINE/RENDERING-GENERATE MESH DISTANCE FIELDS and PLUGINS/NIAGARA-ALLOW DISTANCE FIELDS (EXPERIMENTAL) Both Checked on....I can't see anymore ...I can create I think all the rest of Niagara system elements but this. Any idea please? Thank you!

[@renderbucket]

Make sure after enabling you save the project and restart Unreal. It might require a restart to enable those changes.

[@SamiNaamaniMC]

Can you use this for like a lake and river scene in a game??

[@renderbucket]

Possibly, but for lakes, rivers, oceans, and other custom larger water bodies this may also be a better approach if you need it to run fast. kzbin.info/www/bejne/rZexenihfbiZpNU

How about making sand? with niagara?

[@alejandrovallejo4330]

The liquid in my simulation is gradually disappearing, any idea why?

[@m.a.touhidislam3764]

i love it

[@djtc2093]

For some reason, when you place this system on your map, it only works in the very centre of your map and does not show up anywhere else. Super frustrating

[@renderbucket]

It should work no matter where you place it, it may look like its disappearing in the viewport but toggle the Auto Activate checkbox in it on and off and it should re-appear/recalculate. When you go into play mode it should also work, the only exception is if you move the Box/Container for the fluid Up or Down, you will have to adjust the Water Height parameter in the fluid since that's based on world space (height from 0 (grid origin)) units not local space. Its also odd how it behaves but make sure in your Grid3D_FLIP_FluidControl emitter Local Space is checked off, if that's on it will cause issues a lot of the time.

[@djtc2093]

@@renderbucket Thank you. I will give it a bash.

[@djtc2093]

@@renderbucket Nope. Unfortunately it doesn't work. It only works in the very centre of the map at location 0 0 0. It's not the first time, a couple of the FX in UE5 do this. Who ever invented it is not the smartest human.. Seems completely counter productive. Thanks for the help anyway.

[@renderbucket]

@@djtc2093 there might be something going on there. Im able to move it to any location and it still works. But could also have to do with certain forces you apply. They may need their location set in world space or set to be a local axis.

[@djtc2093]

@@renderbucket Thanks bud. Will let you know if I come right. I've tried in the past, but never got around it.

[@solidstatedrive]

Someone asked if you could use this for a whole ocean, but can you use this in a grid like fashion surrounding an island coast (only interacting with the coast) blending in with "non-simulated ocean" surrounding the FLIP grid, if that makes sense, or is it only possible to use this system in isolation?

[@renderbucket]

What your describing is definitely possible but a lot of tough challenges to sort that out, it wouldn't be a easy thing to do, but could be possible. Would require a lot of custom development. It might be easier just to use more traditional and cheated methods for such a thing at the moment. So no easy/fast ways to do that at the moment.

[@LionUnderwood]

Hello! First of all, congratulations for the content! Secondly, I tried to follow these steps, however when I create the file FXS Pools with the template, the pool of water simply don't show up. The entire interface is there, but not the water pool. Sorry the question, I'm begginer.

[@renderbucket]

Make sure its placed at 0,0,0 in worldspace. And see if it shows up when you toggle auto-activate on the fx system. If it then shows up its because if your placing it higher up in your world/scene you will have to increase the water height to match that elevation/height.

[@БорисКостин-ф6п]

Hi @renderbucket, thank you for your work! I wanted to share a solution to a problem I encountered. I increased the water height to 22000 (as my point is above this value). But it almost ruins my perfomance :( Also, I used the ‘Compile’ and ‘Full Rebuild’ functions, which can be found under the three dots next to the ‘Compile’ button. But I hope this helps others.

[@sosasebastian3033]

The pool is visible in my niagara preview but when it is in my map the pool is invisible. Any idea why?

Check to make sure Auto Activate is checked on and enabled in your Niagara FX system when you place it in your scene.

[@sosasebastian3033]

@@renderbucket Thanks for your answer, but it is on

[@renderbucket]

@@sosasebastian3033 Check the fx in a new scene. Make sure its not something in that scene causing a issue. Also just try creating a brand new Niagara FX Fluid and see if that one works with no modifications. That way you might be able to figure out if its a Unreal/Project issue or a issue with the FX settings.

[@sosasebastian3033]

@@renderbucket indeed in a new level it's working. I believe the issue is when nigara effect is not in a specific z position as at soon I move it, it disappeare. However, collision doesn't work.

[@renderbucket]

@@sosasebastian3033 collision will only work with the actor tags with static meshes, make sure they are set to moveable. If your interacting with a character/rig you need to setup that a bit differently. I can make a video for that if needed. Also, since fluids have the water height control determining how high the fluid fills up the container from the ground (0 in world space on Z) if your planning on moving your fluid up you will have to increase your water height so it fills up to that level. Eg. if you move your flip fluid container 300 units up. add 300 units to your water height parameter.

[@eineatombombe]

Hey, I'm sure it's possible, do you know how to make the water look pixelated/voxelized?

[@renderbucket]

This can be actually quite a tricky and complex task depending on how you want the water to behave. But Ill make a video on the rough idea of making this happen for many different effects, like if you wanted the water to be made up of different items or shapes.
