nParticle and nRigid Force Field Generation on Per Particle Basis MAYA


Hi guys, hopefully someone can help explain this to me or perhaps suggest a workaround?
I have a scene which basically consists of an nParticle system and a nRigid passive collider.
My particle system has to stick to the passive collider so I use the Force Field Generation option within the passive collider. This all works fine and particles stick.

However, I need to control the attraction between the passive collider and the particle system on a Per Particle basis.
I plan to drive the attraction based on other Per Particle Attributes so some particles get attracted based on certain conditions etc.

Is this possible?

Many thanks.
