Collisions not working

[sparker]

I am trying to collide particle with two planes and it is not working. I used curve flow to get my particles down apath and want to sandwich the particles inbetween to flatten them to look more like ariver. i am using blobby particles.
I did what the help file said one at atime and selected the particles than the planer and went make collide under particles it appears not to work and the relationship editor says there linked under collions. i tried adjusting te rssilence and friction but it did ot effect anything.

please help if you can

Are you sure that particle disc cache is switched off? If not, any changes you do on the dynamic parameters in your scene won't effect the particles motion.

Try to change the values for collisionTolerance and stepSize in the rigidSolver settings

your geoConnector node's tesselation factor may not be set high enough if you are colliding with a nurbs object.

your normals may be pointing in the wrong direction for the collision surface.

a good test would be to have a rigid body sphere drop on the plane and see if it reacts properly.
