Tips on how to randomly spawn Niagara Techniques on a floor

Hi there everybody, i’ve been attempting to achieve an impact however I’m kinda caught.

My query is, if there’s a method to randomly spawn a niagara system (on this case it’s only a easy sparks’ burst) over a floor. I used to be attempting to do it inside niagara however I didn’t get something, because the spawn modules are evaluated per particle, and what I wish to do is to spawn a complete Niagara System over a floor and never solely singles particles.

I used to be pondering doing it inside a blueprint, utilizing the road hint node and randomnly spawn these traces, so when the hint hits, the Niagara System spawns over the floor, which I’ve it already contained in the blueprint as properly, however I’m unsure if that is the very best method.

Thanks upfront

Hey! Unsure if I totally perceive. Do you imply spawning particles on a mesh floor like right here? UE5 l Sprint Path Particle Impact With Niagara l VFX Tutorial l Unreal Engine 5 – YouTube

I believe they imply a complete system with a number of emitters

oh okay, that really is smart once I learn once more.
Then most likely blueprint is the way in which

Sorry for the misunderstanding. Sure! I meant the whole system. Any concepts on easy methods to method utilizing blueprints?

hmm I might most likely method it similiarly to you as I can’t discover higher resolution proper now, however perhaps somebody will know a trick for that.

What you are able to do is: learn the static mesh in niagara after which spawn supply partices (emitter 1) on it randomly.
Then add an occasion in niagara (which firers when spawning supply particle), which triggers one other emitter (emiter 2, your sparks). ‘Location Occasion’ is what you’re on the lookout for on this case.

You may also do it with blueprints and line traces, as you had steered initially. You would want to evalute the efficiency value of every of these strategies. My intestine feeling teels me line traces in BP is likely to be sligtly dearer. The prices will likely be on the CPU for each these strategies, as solely CPU emitters in niagara can have occasions. Collision traces in blueprint are additionally value on the CPU.

Yeah, that kinda labored as meant. Thanks for the assistance guys
