Colliding particles with geometry
- Now we'll want to adjust the collision properties for the sink and the drain, in order to make the particles move more naturalistically. Select the sink, go over to the Node Params, and open up Liquid-Particles Interaction, and these are all the properties for the selected objects. Collsions: Collision distance is the distance at which a particle is considered to be touching the object. I'm gonna set that to a value of a millimeter. Type in a value of 0.001. Distance Tolerance is a randomization factor that's going to make it so that the particles don't sort of sit on top of each other in bands. We'll give that just a little bit of randomization, a Distance Tolerance of 0.0001, or a tenth of a millimeter. Going down a little bit, we've got Friction. That's a force that's applied to slow down a moving particle as it slides across a surface. I'm gonna increase the friction a bit, from 0.001 to 0.01. Bounce of course is the amount of bounce; how far apart a particle is going to rebound…
