Heyo ^\_^;  
I have a particle system that is emitting mesh particles. I am trying to get them to angle themselves along their current acceleration or velocity vector. Any ideas on how I might do this? I was thinking I might also just have and actor following the particles location then have the actor orient itself based on the particles acceleration or velocity. Basically I’m trying to make a swarm and trying to come up with the best way to go about it. Any help is very appreciated.

here is how to align mesh particle with velocity, there are also other ways that i have covered in my youtube videos. [Niagara particle direction issue. - #2 by Cghow](https://forums.unrealengine.com/t/niagara-particle-direction-issue/1988183/2)
