is there a way to check if a particle is touching a part and if so that particle will be destroyed? Like when making rain so the rain doesn’t go through roofs and different things? Without using big chunky parts? Thanks
Hey @iuseselfnone! 
I believe that this is something impossible from experience… The best thing to do is to at least make the rain not be surrounded by a model, which for example of, is the house.
You cannot check if a particle touching a part, however you can still make the rain consist of small parts and destroy them when touched.
