I'm trying to make it rain on my T. rex. the rain comes down okay, but when it collides, it makes a new particle as a result of collision events, and its supposed to run down the sides like water droplets, instead it just falls through his skin and collects on his insides like he's a bucket. I think this is because when the new particle is born its already "in" the skin, so the collision is not computed. does anyone know of a way to solve this? is there an expression to put the new particle a little above the skin? any help would be much appreciated.
