How to make rain effect face a particular direction?

I’m trying to use the particle effects from the content examples. How do I make the rain effect face one particular direction? I wanted to use the same effect for a cascade. But it keeps facing the player. I tried setting the orientation axis to X or Y axis, but it doesn’t work. The screen alignment mode is PSA_Velocity. I followed the post How Do I stop my particle system from facing my player camera? - FX - Unreal Engine Forums. But I’m not able to make it work with the content example for my requirement.
