Unreal Engine Rain Particle with Splashes using Niagara FX System 🌧

[@darnb2675]

anyone using unreal 5 if you don't see the event handler it's now located inside of +stage (to the right of emitter properties)

[@d.k.1545]

Thank you!!

[@arunaldo1089]

Thank You. I was searching for the same

[@iamFolegnani]

Anyone having an issue locating the 'Event Handler' @7:45, this is hidden in the emitter. If you click on the 'Stage' for the Rain_Streak (it has an orange cross next to it), it will give you the option to add the Event Handler.

[@instructor_alex]

Bro, as a Ue4 teacher and content creator, I gotta say your tutorials are fire and easy to follow. Definitely recommending your vids to my students, keep it up!!

I appreciate that!

Thank you so much. That was the best Niagara Rain in the youtube! So clear and smart and easy. Thank you

[@poken9293]

if you cant find generate collision event under event handler like me, just wait because he later adds it to the particle update.

I can't find the “Generate Collision Event” in Unreal 5.3.2 (NIAGARA)... It does not appear in event handler, it only appears in particles update... is this correct? and GPU COMPUTE???

[@notgamingwithfaz]

me too

[@borzonstudios8638]

add generate collision event directly to the Particle Update section, NOT to the Event handler

[@manvendrasingh299]

this is epic, thanks!

[@emmarichard6829]

Thank you a lot! I am a beginner in Unreal and I still understood all you did it is super nice

why is there no splash in unreal engine 5 i did everything the same but i only see the splash i i select in the oultiner the object but if i click out of the object i dont see the splash not even the litle dots and with texture

[@HeyRnold]

7:45 I don’t have an event handler option I’m on 5.3

[@derallerechte4286]

one of the best tutorials i ever saw thank you!!!!! but iam working with unreal engine5 will be the effect more realistic with the new engine or do i need some different settings?

[@CodeLikeMe]

well, I have done some updates to the system over time. But the look does not necessarily change with the version. It depends on the material and lighting setup. kzbin.info/www/bejne/h3XUYquDn7Ofhq8

[@derallerechte4286]

@ alright thanks for your answer but i have a other question to. I realised in big maps the rain is very invefficend is there any way to optimze it?? I have the idea like rendering the rain only next to the character or the rain follows the charakter but i dont know how.

My "add event handler" isnt an option on UE5 any thoughts would really help

[@CodeLikeMe]

event handler option is changed in UE5. Watch this tutorial, there I used the updated event handler option kzbin.info/www/bejne/hoGVe5dsrJaAh6M

[@LiMaking]

@@CodeLikeMe Hi I checked the arrow video you linked here and I can't see an event handler option at all?

[@iamFolegnani]

In UE5 the event handler has been hidden. In the Rain_Streak click on the 'Stage' at the top with the orange plus and it will give you the option to add the Event Handler.

[@guilhermenaco]

Hello, thank you! But, I´ve noticed the puddles appear in random places in the level, not on the "ground floor" only. Even after reducing the radius. Do you know how to fix it?

hello, so i wanted to create this effect in ue5, but there's no tutorial on ue5 for this effect. so i followed yours, but it doesn't work. what to do different in ue5??

Is it possible to make it so the rain leaves puddles?

[@bobgratton2986]

I dont have the generate collision event, only the receive collision event why so ?

[@aren4832]

Try in Particle Update section

[@bobgratton2986]

@@aren4832 theres this box to check I was in 5.2 you need to check a box overide collision something like that and then you get access to generate collision event

[@cvelasco88]

There is any way to avoid the rain collision with the character? and a way to spawn another particle/behaviour for this case?

[@CodeLikeMe]

I'm sorry. I am not sure if it is possible to do that. need to research. But if you find a way, please let me know. I'd like to know that.

[@sharathbabu2089]

Im using UE5, i cant find the box location option in particle spawn part, there is grid location and shape location. Please let me know which one should i use. Im a beginner in UE.

[@Unstable.]

I'm not too far in the tutorial yet but using shape location produces the same result as box location so far

[@weichen3621]

hoepfully you found the answer to this but if you didn't the box/plane is in the shape location

[@Unstable.]

Great Video! I'm using the first person template and the splashes appear really big when they collide with the capsule collider of the first person character. Is there any way to prevent this? I know turning off collision prevents it, but then you fall through everything.

[@CodeLikeMe]

may be, modify the splash material to be transparent when closer to camera. or find out if there is a way to scale down if it is closer to the player location, or camera location

[@Unstable.]

@@CodeLikeMe Thanks! I found this video which makes the material transparent the closer you get kzbin.info/www/bejne/eJOqcoprpp1nhs0&ab_channel=EdwardBennett

Hello, is it possible to use 3D assets for the rain in Niagara and spawn 3D splashes when the rain hits the ground?

Of course. You can use a mesh renderer module instead of sprite renderer

[@markrennie86]

right but now theres splashes landing on the collision capsule around the player....

if the roof has collision, raindrops won't come inside

Bro can you help with the sound of this?

[@CodeLikeMe]

I think I have already added a sound to the system

[@pro.giciel9084]

The sprite are kind of transparent in my level, don't know why

[@CodeLikeMe]

check the material setup. if you don't need any partial transparency, you can use a masked material

[@pro.giciel9084]

@@CodeLikeMe It was just the emissive of the material that had to be boosted

[@vivekcharan417]

On unreal market?

[@CodeLikeMe]

No, but this video is free,

[@jacklawrence2221]

could use a lot of RAM during runtime

[@CodeLikeMe]

its just 2 emitters. not that many particles.

[@realemptystudio]

Yeah, nothing works in UE5 Actually, its buggy, fixed something by restarting the engine, also scales are way different than in 4

[@Boris247]

I appreciate the video, but your approach of doing collission checks per frame on every single rain drop is too lazy to be useful because it costs too much performance. I did some testing and this costs ~10% of FPS, which is too much. There is a better way of doing this using top-down ortographic camera view to generate a height map around the player character to detect surface in form of height map, which works even with wind simulation. This way it's 10 to 100 times faster that per-frame collission checking on every rain drop.

[@RusticWharf]

Could you share how to do it?

[@Boris247]

@@RusticWharf I am trying, but KZbin keeps deleting my comment

[@CodeLikeMe]

perhaps you can send it to my facebook page. I'd love to explore what you suggested. also it would be very helpful for others as well. facebook.com/gamedevelopersclub/

[@kuro2ck]

I would like to see this, as my 3090 drops from 120fps down to 40 when the collisions are on. looks good but not useable in a game. :(

[@Juri-xz8qv]

how can i make the rain all around zhe world not just on a certain place?

[@CodeLikeMe]

enlarge the spawn area of particles to match the world. But beware of performance. I only make the rain particles spawn around player, so wherever you go, there will be rain,

Is it free?

@@Hasmatix But he does more this more advanced stuff, have you checked his channel?

[@Hasmatix]

@@Plaston_ yeah stuff that doesnt work on uefn

[@Plaston_]

@@Hasmatix it's because it's a more simple editor than the base UE editor, so you can only do simple stuff also all of his videos mostly worked for me so it might be a skill issue combined with theses little differences between UE versions than screw with any tutorial but this can be fixed if you know what you're doing.

Milk Rain

[@realityengine]

This is how not to make rain in ue5. This method is too expensive.

[@CodeLikeMe]

So, what's the alternative?

[@realityengine]

@@CodeLikeMe some use screen post-processing, some use a volume that follows the the players character. Simply scaling your effect doesn’t account for occlusion of the effect. It takes up memory by rendering outside of the cameras frustrum. You’ll have rain where you don’t want it.
