I want to make a fireball trail but the Particle Emitter is always facing the camera and the trail starts to rotate,that’s not realistic.How to fix this?Thank you very much!!

Hey -

In the Emitter’s Required module there is a setting called “Screen Alignment.” Set this to PSA Velocity and the particle should always orient toward both the camera and the direction.

Let me know if this does not fix your problem -

Thanks!That really works.
Btw,how can i make the particle rotate on its own axis?

You should be able to add an Initial Rotation Rate to get a particle to rotate on its own axis.
