Duplicates: #28814

%%%I'm trying the new blender 2.59rc

Check the video:

http://www.youtube.com/watch?v=tGU-F0Nf8Ko

I've exported the rigged mesh as a .dae file, and then in a new file imported the same .dae file, some axis points to the top.

this is my system:
Ubuntu 10.04 (lucid)
2.6.32-32-generic

%%%I tryed but i've problems to add atachments, gave me an error, anyway i uploaded on my site:
www.hokmaph.net/avatar-rigging-blender25-cubo.blend

(is not the same mesh, but is an example with the same issue)%%%

%%%currently, that's expected behavior in the collada importer. Collada represents armatures as a joint heirarchy, blender as a bone heirarchy. converting a joint rig to a bone rig creates an extra bone at the tip to represent the orientation of the final joint%%%

%%%Matthew, if you look at the video i posted, or if you try to use the .blend file i've linked, you will see yourself that no extra bones are created in the export collada process.

Just the same end bones with the wrong orientation%%%

%%%I committed small fix in trunk (r39820) that makes the end bones use same direction (and length) as the parent bone. While not optimal it is already much better than the default pointing up bone with length 1.%%%

%%%You need a build of trunk with r39820 or higher on the splash screen., the revision you used doesn't have the fix I committed.

I see if I can get the buildslave manager for linux to update the builds on the mentioned site ASAP.%%%
