+1, would also love to have this functionality.
I have characters throwing physics objects at each other, but don’t want the character throwing the object (and only that character) to collide with it as it is being thrown.
So it seems like the only real supported way of doing this, short of changing it to use overlap instead or teleporting it in front of the character, is to make separate collision channels for ignoring every character in the game, which really isn’t scalable at all.
