This mod adds flames and smoke to certain parts' joint break event.
At the moment, these parts include:
-anything with "wing" in the name
-anything with "fuselage" in the name
-anything with fuel or oxidizer as resources.
Note to modders: I'm trying to minimize the quantity of my mods, so I will not be working on this any further. It could use a bit of polishing though, so I am releasing it under the CC0 license, which means anyone can take it and change it and re-release it without even asking me.
