View Full Version : Colliding particles from inside geometry

08 August 2006, 11:59 PM
I'm trying to birth particles inside of some geometry, and have them collide on the geometry's surface using pflow. Currently, the particles pass through the geometry that doesnt face the emitter as if it wasnt there. If I move the emitter outside of the geometry, the particles will stick to the surface.

Short of making a duplicate object, applying the 'normal' modifier to it, and having another deflector on the collision test list, is there a nice way to achieve this?

As far as I know Ratzlaff, there isn't.. I think you will have to do as you say and duplicate the collision object then invert the normals..

Use a shell modifier on your collision object to give it thickness and use a single udeflector. You'll just need to make sure that your integration step is low enough for the collision detection to be accurate.
