Im pretty confused as to why my arm "rig" is scaling automatically whenever I key a frame (or even just scrub through the timeline without even keying anything). As soon as I do so the geometry that I've converted to bones using the "bone on" box in the bone tools menu pops a whacked out scale. I thought checking the "none" box under stretch would keep this from happening, but alas, it does not. If someone knows what I'm doing wrong please let me know.
:shrug:

Thanks!

my guess (and it may well be wrong) would be that the objects u are using as bones were shaped with 'non uniform scales' at some point. This is often the problem when things start scaling strangely, especialy when animated with rotations.
To fix I would suggest using actual bones instead of geometry :(
if you are too attatched to the geometry that u have already made then it should work if you reset the xforms of all the bone objects (no guarantees)

hope it helps, nice modeling by the way.

cheers
