How to create spark when crashing ?

Hello guys, I've watched some video on youtube, when their car crash it will create orange spark like this, but mine not. How to crate that spark. Many thanks ♥

 

hi they probably used slow motion by pressing alt and down key so you can see the sparks but when you just crash the car it's very quick so you can't see the sparks.
hope that helps, have a great day

 

it's really helpful, thank you very much. Love ♥

 

No problem
