I have built a simple starfield using stardust.  I’m trying to then get the stars to move away from the camera with trails following them.  Think Star Wars warp speed effect, but the warp going off into the distance, not coming towards the camera.  A bit like the “Bang” preset but reversed.

I’ve tried Force / Wind with a negative z wind, but it doesn’t affect the starfield particles as they have are already been born.

Any ideas?
