Subject: COLLADA: Take parent bone length and direction instead of using bone pointing up... 
X-Git-Url: https://git.blender.org/gitweb/gitweb.cgi/blender-staging.git/commitdiff_plain/d0d82c69e96e96845a59ad625900a94187dac621

COLLADA: Take parent bone length and direction instead of using bone pointing up with length 1. Looks much nicer and less confusing on larger armatures now.
