Let's build this Unreal Niagara particle sim within 6 minutes

hi everyone in this video i'll be creating this niagara particle system from scratch so first off let's add a niagara system new system from selected emitter and let's select this one add it and finish let's open up the editor and we can see some yeah some sprites kind of floating around here but we don't really want to vendor sprites we want to render static meshes so we add a static mesh renderer i want to render a cube and i want to overwrite the material sets material to something shiny and i want to where is it yeah change the facing mode to velocity also in the emitter properties i want to set the same target to a gpu compute sim and then hit fixed bounds next up there's a bunch of stuff we don't really need we don't need skill color we don't need spray size skill and we can get rid of the noise for now but i do want to add a skill skill mesh size because they're way too big and if they're too big and they overlap a bunch they are going to glitch out like that so let's actually create a curve and set the initial values to something like this so they're small and at the end of their lifetime they shrink all right let's start to add some um yeah some forces let's move it around a bit with wind let's add a point attraction force and let's add a gravity force that's good let's add a vortex force again to create kind of a spin and let's attitude something like this and now it's spinning that set of noise force fix issue so this is where i get really this is where it gets really interesting right so um the thing i've noticed with the curl noise force is uh set the strength to something high and set the frequency to something really low to get these beautiful movements and i can't see that much yet but let me just increase the particles uh yeah the amount of particles and voila it's kind of messy still right um looks like a bunch of flies so we can add another noise let's set this to minus 7000 and let's set this to something like something low but something different oh right the reason why it's so um all over the place basically is because of the drag i left the drag in but you can see what happens as soon as i change this value from 1 to 10. they want to stick together in this beautiful yeah kind of flocking bird-like way that's really the the the big brain behind this particle system basically it's uh this drag force and if we go to the the first noise force we can add a panning so it just kind of uh rotates the rotation around and it creates this beautiful beautiful motions and i think we're done here so let me just hit save and we can drag this system into our world that already looks pretty good but uh it's not reacting with the light per se it kind of is but um because it's not casting shadows um it could look even better so let's just turn cast shadows on and you'll see the light actually disappear into the particle system we can grab the light and we can move it around oh man i love this so much this is crazy so yeah that's uh that's it hope you have fun with it bye

Dope. I just saw the other thread for the first time, scrolled down and saw this one. Accidental instant gratification.

I was one of the people who asked! Awesome man. I clicked through quickly, but I love that its less than 10 minutes and seems to show some basic functionality of niagara. have wanted to mess with it forever but all the tutorials are 8 hour college courses. hahajk. but really. thanks.

YAY!

Thanks!

Awesome, thank you

Thanks for the tutorial!

I feel like, while some stuff can be complex in Niagara, there is also many simple effects waiting to be discovered!

Of course, I wouldn't be surprised for these simple effects to lean more toward the resource-intensive side of things... After all, you can't really create a fine-grained effect without throwing lots of particles at the problem.

Thanks man! This was awesome! To the point and easy to follow along.

Amazing tutorial, already used it works great 10/10 would recommend to everyone and their dog

Yo for your first tutorial this is done very well! Your a natural and you make it nice and simple. I have never heard of these effects, but damn they look cool 😊
