emit from "cut" face

#1

Hi,

I’m struggling with an effect where I have a simple box with a scapel modifier (or slice) and I want to emit particals from only the face thats gets created as the scapel moves across the box. There doesnt seem to be a way to emit from object id’s. Scapel can assign an id to the new face it makes, so this would work perfectly.

I have messed about with making a muti sub object with 2 materials, as the cut face gets a id of 2 the rest is 1, but I can not get the particles to emit based on the material either!

I think this is a very easy problem, just completely stuck!

Please help, client is very keen on the effect!

Thanks
Mark

Add Vol.Select modifier to the cut object, select faces by Material ID, then emit from Selected Faces.

Worked first time, thanks Bobo.

On a slightly related subject! I have added this effect to a small collection of boxes and its very realtime, and responsive, but once I move it to an object that got 100 different elements, its very slow. How would you suggest is the best way to keep Pflow systems responsive, and managable?

Thanks,
Mark

EDIT: It seems to work better on collapsed geometry, not extruded splins. Also edit mesh is better than edit poly.
