I’ve created a script that will create chains of stretchy bones in Max. It’s free!
old script below:
Here is link to v1.3 - updated on 10/01/10
[b]Why I created this script:[/b] I've been rigging a few faces lately, and I found it was tedious to create the same stretchy bone constrained to point helpers over and over again. Then I got tired of merging in a file with a stretchy bone already setup. In addition to that I wanted a way to quickly create an arbitrary number of bones already linked together in a chain. My introduction to stretchy bones came from Louis Marcoux ([http://www.louismarcoux.com/Videos/MuscleObjects.wmv](http://www.louismarcoux.com/Videos/MuscleObjects.wmv)), so these bones are based on his method of creation, however, I've removed the point helpers and instead used spheres. I see tons of people using stretchy bones for all kinds of different things in Max, so I hope this takes the tedium out of them a little bit. [b]How this script works:[/b] You have 1 input and 2 buttons, for now. The input determines how many bones are created, and the first button creates X number of bones in a line at the origin. The second button removes all the created spheres and bones from the scene (using a naming convention). It's simple and to the point.

And it does that for any number of bones you want (I limited the spinner to a maximum of 100 bones in a single chain, for now). [b]Upcoming features:[/b] Coming up soon, I hope to add in the ability to create the bone chain in a ring, for mouths. I also want to create a ring with stretchy bones branching off each animation control, just like the one pictured below and on the right (image © [tysonibele.com](http://www.tysonibele.com)): [img]http://tysonibele.com/Main/Tutorials/Face/face7.jpg[/img] I may also add a button for creating stretchy bones in grids, for rigging a deforming wall or other type of object. [b]Support:[/b] I started learning maxscript a few days ago, so I don't know if I can support this across all versions. I can test on Max9, and will try to fix the script so it works for your version of Max, if you run into problems. I hope there aren't any compatibility issues, as I didn't use any ActiveX or DotNET components/objects. [b]Feedback:[/b] Please feel free to tell me where my code sucks, as the code is not encrypted. I want to make it better/faster and version independent, but I'm not sure how to go about doing that - so give me feedback and criticism and I will do the dirty work. Happy Maxing! :) [img]http://www.garrickcampsey.com/media/stretchyBonesCreatorV03b.jpg[/img]
