When i said basics, i meant bare basics (:P) I don't know enough coding to
know how to set my own rules. I know i'm a complete noob at coding, but i'm
really trying to learn. Could ya help me out with an example?
Also from what i can see this will create a splash when the rain trace is no
longer in the air - but regular rain goes right through props. So, splashes
wouldn't be created on props, correct? I don't care if they're not, i can
always just create brushes for that.
Sorry to be such a hassle, i probably shouldn't have started on something so
advanced, heh.
