As images can't be posted here I made this in my own forums:
Getting Started with particles in Unreal Engine Runtime Demo

It's got pictures!

What we want is akin to follow source in that you move the emitter and the particles move with it. The only difference is instead of the emitter changing positions it's changing rotations, so the particles in space should turn with it.

CODE
How it currently works:

-  * *

  *
/    *


How we want it to work:

-   * *

   *
  *
/

Legend:
* = particle
- and / = emitter at different rotations
This is already possible: set PSYS_SRC_ANGLE_BEGIN and PSYS_SRC_ANGLE_END to 0 so the particles come out at the same point on the emitter, set PSYS_SRC_BURST_SPEED_MIN and PSYS_SRC_BURST_SPEED_MAX (not PSYS_SRC_ACCEL but can for variation) to something (both the same) to push the particles out, set the prim's horizontal rotation to an angle (like 45 degrees), and stick an llTargetOmega rotation [use llRot2*(llGetRot()) for more control over the rotation axis] on it. Throw some PSYS_SRC_OMEGA rotation on it for more fun. llRand the parameters in a timer for even more fun. You can do so many things with particles if you just dork with 'em...

Bump for great justice, I don't think this feature should become another forgotten idea as I have a project which could use a couple of the features touched here, is there a feature proposal made to vote on?

So I guess my idea for having a multistory house with a transport tornado in the center is a bit tricky...................???

Well.... if I were to try it... I'd use animated textures on linked pairs of cyclinders offset from the central axis a little bit so they wobble some when told to rotate with llTargetOmega().

But that's just me. :)
