How to spawn particles in random rotation and have them move based on their rotation

My engineer seems to be having problems figuring out how to do this (but just started earlier today), how would one go about achieving this?

Thanks in advance UEforum

You can make a particle rotate to follow it’s velocity, but not the other way around.

To do this, Go to the ‘Required’ module and change the ‘Square’ drop-down to ‘Velocity’. At this point, X and Y for size parameters become valid.
