I received this tutorial from you a few days ago and it came at just the right time. I was finishing my first music video for Universal Music, I couldn't be happier, and I used this Cryogenic effect in one of the final scenes. The final touch, you raised the bar on my work, thank you very much.
That’s great, thanks for letting me know!
man your tuts are next level simple and effective
Yes keep posting about Niagra simulations... Its really helpful. Thank you so much bro
I've always been afraid of getting into niagara tutorials, but when I see this one, it really makes me want to learn more!
Thank you so much!
The first few videos in the free course are ultra-beginner friendly, nothing to fear 😄🙌🏻
Best tutorials on TH-cam!!!!!!
I WISH I COULD LIKE THE VIDEO MORE THAN ONCE!!
GRATE JOB MAN!!!
Nice short informative tutorial
This was easy to follow and helped me create some really cool effects for a shot. Thank you!
Clear and concise teaching. Exceptional work sir. Thank you!
Thanks a lot!
great video! and well done, thank you for realy breaking down everything
As always super relevant
Amazing Intro, thank you for that great introduction. Make more please.
thank you for your tutorials
yes please make more! Would love to see how we can animate these fluids , like starting or stopping the smoke from emitting from a pipe! great tutorial
Good idea, noted, thank you 🙏🏻
yes we like your content , dont give up
Awesome!
Really good. Thanks.
My VFX job was canned thanks to the ongoing strikes and overall downsizing, so I decided to have a go of getting into some real-time effects. So finding your videos has been immensely helpful, thank you. If I can spare a few dollars I'll grab a course from you sometime.
Thank you. Hope my stuff will help you
Thanks a lot for your time ! I'm implementing this on a drone crashed on a distant planet, it looks so well :)
Awesome, would love to see it
Thanks a lot !
Fantastic tutorial, really easy to understand and follow! Thank you
I wonder if fluid simulation is usable in real time games or is it way too heavy? Is exporting a multi-frame texture into flipbook in EmberGen is the best way to have fluid vfx into real time game?
thank you
and more unreal 5 tutorial from you would be awsome
This is only the beginning ✌️
good
Very nice tutorial, easy to flollow, concise and to the point. However, I tried in 5.4 which looks different. Would be great to see it remade in 5.4
No major changes in 5.4 and sims about the same for me. What looks different for you?
I really like to watch your channel. Can you make a tuto for doing realistic fire on skeletal mesh like you did for this one? thanks :D
👀
Keep an eye on the simulation resolution for older RTX cards. This sim crashes my 6 year old RTX 2080, keep the resolution no higher than 300. Great excuse for an upgrade and great tutorial!
Hey man ! thank you so much for this quick and well explained tutorial ! Been playing with this Niagara System this last couple of days and i been wanting to find a way to make the emiiter spawn the smoke by intervals, is there a way to do it ?? Eg. The Sphere Emitter "emits" smoke for 2 seconds, then stops for 4 seconds, and spawns smoke again for 2 seconds, looping it that way without killing the system or the emitter completely , hopefully i made my self clear lol ! Thanks in advance anyways !
awesome tutorial sir. I tried to make the monster a geometry collection (to destroy it with chaos) and suddenly none of the collisions worked ? I ticked the geo collections box in "collide against" but nothing worked...
Your tutorial helped me a lot. Could you please tell me how to make smoke appear after 10 seconds when rendering with sequencer?
Thanks! This is covered in my Niagara Fluids Immersion course
Awesome tutorial, was exactly what i needed, except for one small thing. Do you know how to make it burst out the smoke rather than having it spawn as a stream, or at least stop it from spawning after some time? Tried cancelling deactivating it in sequencer but the whole smoke disappears.
All covered here: RedefineFX.com/blast
Great work man,awesome.We re just about doing our old sci fi game a remaster,and we have a cryochamber.I really wanted the free lessons.but i applied several times,but didnt get it in my mail.was it limited offer?
Very rarely there’s an issue where it doesn’t send. Please check your spam & if it’s not there email me and I’ll send it manually
Thanx you so much😀
wonderfully informative tutorial. I am wondering if theres anything you suggest when getting gpu crashes in doing a cinematic render. I've set the max axis to 1000 and get a gpu crash when doing a sequence render on my rtx 3090.
Is 1000 just too much?
Try caching the simulation first before rendering
@@RedefineFX awesome thank you for the tip!!
Hello there!
I have a question for you:
When we do a render in the MRQ, how can we get the simulation working directly from the beginning of the sequence, and not waiting for the smoke to fall on the ground? (its taking to much time for my scene...)
Is there a setting to adjust?
Thank you for your help! :)
Gotta cache it first
Hi there,
Why Niagara sim, exactly from Your tutorial, I mean I don't mix nothing more. Only is flowing as it should while I point viewport at it? When I'm not totally looking at the emitter, the system isn't behaving as should at all. Also I can't render because it can't follow it... What is wrong?
Is there a way to animate the emitter in secuencer so it stops blowing smoke in a certain frame?
Yes, using the sequencer
how to render this smoke in path tracer ?
Does this dynamic smoke works with alembics or just skeleton meshes
works with any imported mesh also
When i try to add the niagra system it says Compilations failed. Not sure why. Any ideas?
What hardware are you running it on?
I just can't believe what I am seeing. 🙀
😎😎😎
Thank you - how do you clip/remove the spherical smoke
source from the scene?
You can disable the sphere source but then you’ll have no smoke unless you emit it from something else (eg particles)
Yes, I know. I have a similar problem in Houdini sometimes. In Houdini, I ramp up the opacity of the smoke so you don’t see the spherical smoke source, but I was wondering how to do it in unreal…
it looks great, but could i use this in an actual pipe line in dev though?
Who knows? A lot of people use unreal who are not in game dev
Is there a way to turn the animation into a svt (sparse volumetric) so that I have better performance?
Yes you can cache it
I am wondering if VR can handle this type of sim yet
my 3D gas master emitter works in the design area but not in the level scene when i drop it in its empty doesnt show anything? im using 5.3 too
If the Gas Simulation is not visible, or not updating as expected, force a Full Rebuild of the system. You can do this by selecting the option under the '3 dot' menu next to the Compile button.
Make a vehicle hotbox scene where smoke billows out the window! :)
Lol yes please
Thank you sir for the free course! I'm taking it now :)
hi how how can i change the emitter shape from a sphere to a box?
Not straightforward to do. I have another tut on how to emit from objects
I just finished this video and the effects looks great, however when trying to render it out as video the render get significantly more smoke than in view port.
You may have a scalability override turned on just for rendering
Are there any modifications necessary to make it work in 5.2?
I’ve been told a bunch of stuff doesn’t work the same in 5.2
@@RedefineFX Thanks for the reply. I generally use Reallusion for my characters and they don't have a live link for 5.3 yet, but I'll still be studying your course. (Just signed up for it yesterday) Looks great, your talent and tutorials are greatly appreciated.
Cool! Thanks a lot@@borrowedtruths6955
It seems my smoke isn't colliding like it should with the monster. I added the tag to the monster just as you showed in the video, but I can't get the results you have. It looks like the smoke is colliding with the monster in it's beginning pose, but the smoke doesn't move when the monster moves its arms through it. Any idea what this might cause ? I have an RTX 3090 and Ryzen 5950X, so I don't think it's a hardware problem.
try cranking up the pressure solve iterations higher. also try enabling distance filed collisions under the gas emitter collision tab
@@RedefineFX That doesn't make a difference. I tried importing a simple Megascans mesh and when I move that manually through the smoke, the smoke isn't following. In the Particles lesson this worked (particles inherited the velocity of the object that was interacting with them), but there's no effect of the monster animation on the smoke...
@@RedefineFXI can't get it working. Would it be possible to share your UE 5.3 file please ? Thanks ! :)
@@lucvw1975 I tend to foget saving and/or compiling in Unreal... maybe you do, too?
@@andreasfaltin960 Thanks, but that's not the case 😕
please make more UE5 tut videos
they're coming
Hmm, just testing it on 5.3 according to your setup, but the smoke seems to be pitch black. Trying it in my custom scene, but also in UE default archviz scene. Any idea? Thank you!
Are you on a mac?
@@RedefineFX Hey! No, PC Windows, I am running it on rtx 4090 so I really can't blame the HW. Looks like some lighting issue.
@@orphanRTGIn that case I have no idea. I've only had that issue reported from a Mac user.
@@RedefineFX Hmm, interesting, no worries, at least I know this issue occurs. It is not necessary for my current project, just testing it. I guess it´ll be fixed later somehow anyway. Thanks for your reply and keep working on your amazing things!
small update from my side, not fully resolved tho. I realized the error might be caused by light/shadows. When I have the smoke in the scene it is pitch black only when it is affected by shadows coming from another object in the scene. When I move it up so it is basically in the thin air where no shadows from the environment/ other objects occur, it seems to have correct colors. Not sure if this is the same error that is happening on Mac.
Hi mate,i am trying this on my mac m1 and the smoke is completely black, its not grey like yours...any ideas why and how to fix it?
known issue on macs, no fix yet
Thanks for answering, and for the free course too,thats awesome@@RedefineFX
I'm trying to drag and drop my niagara asset in my scene but it doesn't display. It does display on the test opening level tho. I don't know what's going on do you have an idea ?
No clue I’m afraid
@@RedefineFX Could there be anything like in a post process volume or volmetric height fog that prevent the niagara system to show up ?
bro i tried what you wrote but it didn't come grid3d_gasmaster_emitter option i didn't get bro anything to do
uncheck library only in the emitter selection window.
is that possible to take EXR render with gas emitter simulation. i tried both cache and real time its not working??
I haven’t tried
how will you take that render that shown in tutorials..legacy render?
@@RedefineFX
it's just viewport capture, I'm not rendering anything out@@unreal_enginemail
is that any possible to take that volumetrics png,EXR in render? i tried its not working@@RedefineFX
help please hey i have niagra fuild on but the problem is i cannot see gride 3d gas master emitter in my emitter tab
ive got the same pb did u find any solution ?
i added collider in the tags but the smoke is not colliding to my mesh
It should collide with everything by default in 5.4
my "parent emitters" section is empty :( ... any advices? thanks
uncheck library only
The tutorial says 5.3, but can it be done in 5.1 as well?
Negative. 5.3 recommended
I have 4070 super 12 GB but I am facing crashing issue when I set quality to 300 so can you help me what needs to be change
If it’s crashing it’s because you found the limit of what your GPU can handle
@@RedefineFX how to resolve this issue I am using 12gb 4070 super and I set smoke resolution to 300
Is this real-time? As in, how many ms? And what’s your hardware?
Yes it’s real time and I don’t know ms I’m not a game dev. 4090
@@RedefineFX the engine gives statistics on the render times in ms… that’s what I meant but thanks for responding… 4090 seems a little too high end for my taste. This real-time would likely go to 10 fps on an average pc. Doesn’t seem game ready, I was excited watching the video 🥲
Thanks again for the tutorial though… hopefully soon Epic will come up with a way to solve volumetric simulations quickly in real-time under 5ms
No master node on my end. did they change this
@@deasmeofficiel2960 you 100% have to use 5.3.
I was trying to follow this in 5.4 and that node doesn’t exist in 5.4.
Incorrect. Just search “master” in the template window or scroll down through the template emitters till you find it.
@@RedefineFX took you long enough lmao thanks
Great tutorial, thank you for that ! But here a nerdy comment: Why is everybody calling it "niagra" ?! It´s called "niAgara" like the Niagara falls, or am I wrong ?! Again, sorry for beeing a pain ; ) ...The tutorial IS great!
I'm so grateful for this comment. I kept calling it like that too, niAgara - just feels natural. But the correct way rhymes with Viagra (that's how I remember it lol, and I googled it and that's how google and people at Epic say it). It's a pain for me to have to say it like that, and I correct myself all the time when I record these tutorials...www.dictionary.com/browse/niagara
Just looking at this, I think my gpu will start producing smoke before rendering a single frame
