Hey there,
For some of you this would be very simple i guessse but I'm just not seeing it.
What I try to do is to blow some particles away with a random wind force per particle.
The problem is that the DOP network sees the particles as one big object and not as individual particles.
Is there a way to use $ID or $PT in the DOP network.
When I look under particle_emitter2/Geometry in the detail view I see all the point information but I don't know how to access that information to use it in an expression.

thx guys,
c

may I ask why you are using a RBD solver? It seems to be that you are trying to do something similar to this tutorial (but without using the color info from an image)

Anyhow, perhaps you are trying to do something else.
