excluding a particle system from collision

Support Animation and Rigging
1

i have two particle systems in my scene, one is supposed to interact with a collision mesh and the other is supposed to ignore the collision mesh.
How do i go about that?
In 2.4x i would simply but the emitter for the system that is supposed to work without collision on a different layer.
In 2.5 however the particles are influenced by objects on all layers.

I allready tried setting all the values in the “field weights” tab to 0
and limiting the effectors to a group in wich the collision mesh is not in.
But so far nothing has worked.

is there a secret “no collision” checkbox somewhere that i just havn’t found?

Thanks.

I think you are right, it is a bug. Report it quickly and it will be fixed quickly:p

Just use 2.49.

Blender 2.5 is not ready for daily use yet. Vote in the poll and let them know that you can’t use it because it is still full of bugs.
