This was a script I developed for my portfolio. I think you guys will like it a lot. It allows you to chew the edges of sharp corners to make them more worn. It's stable, and includes lots of cool features like frequency of the cut, the depth of the cut, and the randomness of the result. In this latest version, you can access the macroscript from the utility panel (maxscript), add it to a toolbar, or even bind it to a hotkey!
The link below has a demo .max file (Max 9) where you can see an example from the script!
