[@virtualfilmer]

It’s crazy how good your tutorials are. They are honestly the best on KZbin. I think it’s the way you explain things - SO easy to understand. Plus your voice is easy to listen to for hours. Please keep up all the hard work!

[@sarkamari]

Not sure about my voice, but I am glad the videos are easy to follow lol

[@Panzergamingstudios]

Dude best tutorial hands down. I have been working with unreal since UE3 and even UDK. Had early access to UE4 before it came public 2 years prior. I am finally diving into Niagara. This tutorial is amazing. Keep up the work. Am definitely subscribing.

[@sarkamari]

Great to hear Matt💪🏼🫶🏼

[@KaliadderExperiments]

I can not say enough how wonderful this tutorial is! Just simple, straightforward, gave me the absolute foundation of what I wanted to know to a) get me started and b) carry with me to create on-going ideas. Thank you so much!

[@niiranen]

Very usefull tutorial, needed to learn about simulations and this did the job! Thank you!

[@sarkamari]

Great to hear

[@ataman064]

A good lesson. Or you can let the water flow along a given trajectory. For example, in tyflow, the movement of particles can be done along a spline

[@ohheyvoid]

Thank you so much for this. It was so helpful!

[@galbezalel2762]

Thank you for this awesome tutorial! could you please share how is it possible preventing from the water level to go down?

[@emirunalan1287]

I'm trying same kind of a setup for filling a cup. But it only uses a bounding box as a collider for the cup. Did you have that kind of a problem before?

[@nocopyrightfsa3237]

Thank you for this tutorial

[@johnnatanguimaraes575]

Firstly congratulations on the video tutorial! your explanation is great! I also have a question... I use UE 5.2, I downloaded a megascans stone, I tried everything I could to create a collision but I couldn't, am I doing it wrong? Or is it not possible to generate collisions with these downloaded objects?

[@subhransupriyadarshan]

Can the bounding box shape be made cylindrical ? Because my static mesh is a storage tank

[@ashskyqueen]

Hi Reza. Great videos! Would this be a viable way to make a large waterfall for an open world game or would you recommend another way? Also thank you for making these videos. I'm new to Unreal and I am finding your videos extremely helpful :D

[@sarkamari]

Great to hear Fluid Niagara sim is not quite production ready yet. Although it’s getting better. For games I still prefer using materials or blueprint. There are plugins also available but they’re rather expensive. Check out my water material videos for more info :)

[@ashskyqueen]

@@sarkamari Will do. Thank you :D

[@plasid2]

will be great if you make some river mountain tut

[@juanjotresde]

Really useful but...what if the fountain is facing the opposite way? emitter will always flow the same direction no matter what I rotate

[@ravennest1374]

such a great video! I was wondering how this would work with a round container, for example a glass? I made the glass a collider, but the water simply falls through it and collects in the box shape. (it only interacts with the water when the glass is moved)

[@EnzoLuka21]

hey thank you very much for this. Do you know which settings allow me to fill the tank from the bottom? Thanks

[@sarkamari]

You’ll want to tweak the Emitter Properties and adjust the Velocity or Direction settings. To fill the tank from the bottom, set the velocity direction to push particles upwards from the bottom of the tank. You can also play with the Position and Spawn Rate to get the flow right.

[@caiozulian2509]

Thank you very much for this amazing tutorial Reza. That was super helpful! I have a question and I hope you can answer. This template comes already with the sphere location. If I want to make it look wider, more like a waterfall. How do I change that?

[@JiggywattArt]

Looks great! Thanks for the tutorial. Is there no way to change the parameters that have the lock icons? Looks amazing except for the cartoonish blue color which I can't seem to get rid of.

[@muhammad_faraz_ali]

Amazing work. How you created the square?

[@motivationalmusafir7999]

thanks sir.

[@Robin-sd8jl]

Thank you Bro

[@24vencedores11]

Very nice my friend. I wish to know how to make it inside sequencer

[@sarkamari]

Please watch my intro to fluids Niagara from the playlist 😀

[@andersonalves6840]

Hello your video is amazing! but i d like to know how can i rotate the sprite? can i just turn to the other side?

[@Sozidater]

how do I turn this whole system around? Only the pool turns, but the jet stays there.

[@alanramirez4294]

if you want to change the orientation of the emitter you have to change to negative values the (PARTICLES) velocity in the axis you need.

[@MatthewWarnerVA]

Thank you for this tutorial. When adjusting the emitter size and location, do you know how to adjust the rotation of the emitter?

[@felipebuenno94]

I use the 'Velocity' attribute, which is set as positive by default, so to flip it, simply input a negative value.

[@apollogt5506]

thank you for doing this tutorial. I activated both NiagaraFluid and NiagaraSimCaching and restarted UE5.4.4, then i grabbed the Grid3D-FLIP_Hose into the Content Drawer, and finally dragged it into my scene and nothing happened. I tried the NiagaraFluid smoke and fire too and nothing showed up. i managed to get some smoke to show up from Gid3D_Gas_ColoredSmoke but it came out as black. Is it having something to do with my graphic card? I'm on a Mac with Apple M1 Max chip, 64 GB of Memory, and Mac OS Sonoma 14.6.1 running UE 5.4.4 Please help. Nobody else seemed to figure it out and they claimed to be pro on youtube

[@TwigsGames]

I have quixel bridge assets that refuse to have collision with this, is there any reason why this could be?

[@kudlak696]

I'm just trying to do the same thing but on a small scale (pouring water into the sink) and I can't handle it. I am afraid that the Niagara fluid system is not yet fully prepared for small scale use

[@walaahamed7961]

very very useful Reza, Its really useful , and step by step clear explanatory tutorials for beginners.

[@sarkamari]

Great to hear!

[@raspas99]

Is there a possibility to do a flip simulation in other software and import it?

[@sarkamari]

Yes. You can bring them as cached into the sequencer however you wont be having editing capabilities inside Unreal

[@TheJesseD05]

doesnt seem to work in 5.3, getting compile errors on all the 3d water templates to do with the system spawning at a vector and a position. ?? any ideas anyone?

[@sarkamari]

Unfortunately the compile errors you're encountering with the water fluid system in Unreal Engine 5.3 are a known issue, particularly when dealing with Niagara Fluid templates like Grid3D_FLIP. These errors often relate to mismatched variable definitions, where attributes such as GridCenterPosition are defined both as a vector and position in different nodes. This inconsistency leads to compile warnings and runtime issues. A potential workaround involves reviewing the specific modules and ensuring compatibility between the variables. Another user-reported tip is enabling all Distance Field-related settings in the project, which has helped reduce errors in some cases​

[@K1N3RGY]

Unfortunately when expanding the world grid extents to fit the box (3kx3k) the fluid now seems like a soft rubber. Is there anything I should of changed to carry on getting the water effect you did? Update: Increase “Num Cells Max Axis” to achieve the above in a larger scale

[@hotsauce7124]

Is it possible to change the bounding box holding the water to a circular bowl?

[@ValThicc]

use a bowl shaped collision thingy i imagine, from a fluid simulation angle it would be incredibly hard to simulate anything other than a rectangle of fluid, so youre just gonna have to make a rectangle with side width equal to the diameter of your bowl

[@hotsauce7124]

Thank you@@ValThicc

[@香喷喷的烤全羊]

Why can only the ball interact when the static net entities have modified the exact same label and the other models go right through it

[@--yamen--]

hey i ues UE4.27.2 in my College . would that work on it ?

[@sarkamari]

I am afraid it works only on UE5 and higher

[@michaeljohnson7012]

i would i change it from a box to a circle like i was filling up a glass?

[@sarkamari]

Put the glass in the container and make the glass collider via tags

[@MaryReedPhantom]

[@burgi6236]

Every Fluid thing in Unreal is either BETA or Experimental, since AGES. Epic needs to get their stuff in place :/ dont wanna purchase a 400$ plugin to create water. Also voxels, not included. Starts to feel like a shopping center like app rather than a complete Engine

[@burgi6236]

@@iva_creative hm?

[@THEHUMELYAKS]

You need to pay for Niagara???

[@burgi6236]

@@THEHUMELYAKS I mean plug-ins for water simulation, you can make everything alone, but Features like that have extra cost. And that's quite alot money for small devs 😇

[@THEHUMELYAKS]

@@burgi6236 ah I see

[@spellhouse]

It’s practically free software for 99% of the people using it. Epic doesn’t owe anyone anything. It’s okay for them to add, at no cost to you, beta features which you do not have to use. The marketplace is a way for independent people and Epic to make money which, in turn, keeps people employed so that you can continue to receive the engine for free, and people can make money doing things they enjoy. Fluid Flux is expensive, sure, but the cost is justified considering there is only one person responsible for its maintenance and development. If it were a simple task to build such a thing, there would be other free and/or cheaper options that would make Fluid Flux irrelevant. All said, be the change you want to see in the world: make a free, high quality water simulation package, ask Epic to hire you as a maintainer, and save everyone $400. 😊

[@DieBieneFranz]

someone else has performance issues with this plugin? My graphics card isn't the worst, but it catches fire as soon as I use this simulation shown in the video

[@jerfi6592]

me too :/

[@DevinGregg-gw6oo]

Has anyone had success with packaging a Niagra flip pool project? Whenever I build with the Niagara fluid plugin enabled, I get an unknown error and my build fails.

[@theJourneyuncovered]

How can I rotate the sphere. when I rotate I rather rotate the container

Not sure what sphere you’re referring to? The collision object?

This is amazing! Thank you so much! is it possible to get particles and fluids interacting in a real manner in UE5? for example using this method shown is this tutorial : kzbin.info/www/bejne/bHTLp5purtCklck with the fluids? also can we render Niagara with Path tracing?
