Re: RE: [Virtools] Particles / follow curve

Looking at the Particle System Interactor attributes (open the Attribute manager for a nice overview of what attributes are available) 
I think that Particle Tunnel sounds like the thing you need.
The description in the documentation however is a tad vague...
<quote>
Tunnel: The Tunnel interactor conduct particles nearby thru the tunnel, accelerating or decelerating them. You can set the velocity aimed by the particles travelling in 
the tunnel, the absorption radius of the tunnel, the attraction shape modifies the force of the attraction, the attraction speed, and finally the attraction direction which 
represent a force modifying the direction of the particle itself. 
</quote>

Maybe local wind or magnet could be of some use too... haven't used them before.

Good luck experimenting

Ciao, Patrick
