Niagara two systems with one emitter or one system with two emitters?

Hi,

Are there any significant performance cost of having Niagara systems for every emitter (exaggerated example) rather than combine multiple emitters into one system?

For example i have 2 wings trails emitters. I can combine them into one system and have hard time adjusting the position. Also i can put each emitter into individual system.

Does it worth to combine this 2 emitters into one system or performance hit would be insignificant ?

Thanks for any advice !

Having two separate systems with one emitter each will be significantly slower than having one system with two emitters. Each system adds overhead for component creation, tick, scalability checks, script execution, etc.

Similarly, if you can combine the wings into one emitter with two renderers, it will be faster than two separate emitters with one renderer each.
