Say I am trying to create a particle system that looks like a water hose which is spraying water particles in the direction that the hose is aiming. When I rotate the hose, the water particles would to change the direction they are moving to align with the direction of the hose, so they look like they are coming out of the hose, in the direction that the hose is aiming. Also when I move the hose around quickly, the water particles would also inherent the speed of the hose, and continue moving in the direction the hose is moving.
I am unable to achieve this effect in UE4, and no-matter which way the parent emitter is facing, or moving, they always emit in the same direction, and appear rigid.
Thanks for any help on this!
