Thanks James,
I've done it a bit different. I've modeled a car chassis in a third party 3d app
with 2 exaust pipes, then at the place when the emitters needs to be within the
pipes, i've placed a little plane in each pipes.
The planes are the exact place of the emitter(s). I was planning to use those 2
planes as a position reference, then when the particles are added to exaust 1,
clone it using exaust2plane as position again, then remove both planes from
world.
I'll try that today...
