The best way to randomly spawn Niagara Techniques on a floor

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

My query is, if there’s a approach 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 nicely, however I’m undecided if that is the most effective strategy.

Thanks upfront

Hey! Unsure if I absolutely 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 feel they imply a complete system with a number of emitters

oh okay, that really is sensible after I learn once more.
Then most likely blueprint is the best way

Sorry for the misunderstanding. Sure! I meant your complete system. Any concepts on easy methods to strategy utilizing blueprints?

hmm I’d most likely strategy 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 might be in search of on this case.

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

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