When I hit metal with the realistic lighting, is the metal meant to constantly have a charge go through it? It seems to be as if I'm holding a spark to it, and it doesn't stop.
Sometimes, the lightning is so hot it causes the metal to melt a little, then turn solid again. Once the metal solidifies, it can take sparks again at a time when it couldn't have before, this can lead to an infinite spark loop.
It's technically a bug, but it wouldn't be very easy to prevent. Maybe I could make solidified metal unable to take sparks for a few frames, or something.
