I’ve been looking into trying to setup a school of fish but I need some help getting it to look right. For this instance, I need to be able to have potentially several hundred fish in one school and the issue I keep having is I cant keep them moving in unison. I’ve seen examples of people using particle emitters on splines but I would like to have this attached to a roaming actor.

Basically, right now my mesh particles spawn and follow a set trajectory and die off if they get too far from the source but I want them to keep their relative position and rotation relative to the source so that when the source actor turns, all the mesh particles will turn with it rather than die and respawn.

in the required module there’s a checkbox for ‘use local space’ if you select that the particles will move in relation to the particle system. then you add the system to an actor and move the actor.

Wonderful, I had the control actor sorted out it was the local space that confounded me it seems. Thank you.
