Hello! I have a particle of rain and it is necessary that it does not go in buildings and for this it is necessary that the droplets are destroyed on the roof, but this does not happen. In the settings I have enabled distance field and set bounds in particle.
I had an issue with trying to keep smoke/dust particle from the interior of a car. At the suggestion of someone, I tried pixel depth offset into sphere mask with a OneMinus to have the opacity end at the outside of the vehicle to great effect.
To the cameras inside, it appeared like the smoke was just traveling around it as we drove. Perhaps there’s a way you could use that?
