title: How do I make dynamic 2D collisions faster in unity?
body: <p>Currently I'm working on a 2D game with destructible terrain in unity. It works great! Except for one thing.... collision generation... Since the terrain is destructible, I have to generate collisions on the go. I tried and it's awful performance. From 1000 fps from editing the terrain to 1 fps when I enable collisions generation. This is a huge issue and I know it's possible within unity because this guy :

  created it with collisions as well. I tried contacting him but no response yet! Any of you guys have any ides on what I can do? Thanks!</p>
