It bugs me (just a little) when people say they don't like to animate with biped because you can't scale limbs. So...I made a tutorial that teaches you to create Custom Attributes and Wire them to a Biped. The tutorial download contains a short Step by Step PDF file and a sample Max file with animation. Download Here.
Thanks for the kind words. I've been wanting to write more tutorials. Any ideas for topics? Animation, rigging, or scripting tutorials? Was the format for this one easy to read and follow? Thanks again.
Thanks! I've been exporting to fbx then re-importing into max to do stretchy bones, so this will come in useful. Thanks for all the great scripts too by the way...
