Orienting particles based on velocity

Hi,

I would like to have some particles emited from a center (emisor) towards all directions (360 degrees). This can be done pretty easily, the problem is when I want to orient each particle based on the velocity vector. An example of what I need can be seen in this video when squares are destroyed: Blokshot Revolution by Foxhole Games - My High Score - YouTube

Cheers.

In my tests, a Particle System with Renderer’s “Render Mode” set to “Stretched Billboard” does something similar to your needs:
