What does Weightless Bodies/Objects do?
You can essentially pick up anything like its a piece of paper and throw it around like it's worthless trash. Bodies and objects still act normal and everything they can just be picked up easier and you can pick up things you were unable too.

I do NOT recommend picking up cars...

Saw this was mod has not been created yet and I used it in Skyrim so I created it. It needed different tweaks then the Skyrims version which is why it probably has not been made yet.
