This is strange… I have a very simple armature (created from a BVH file). I group some of the bones in it, and save it to a blend file.
I open my new blend file and try to do a LINK/APPEND. I select the Blend file I just saved out, and no groups show. If I select the armature, and click load, the load dialog goes away, but the armature has not been appended.
There is no error message or anything… but the armature is not there. Neither are the groups.
I exit that file, and pull up the first file… and there are groups and everything. But it WILL NOT append or link in (I have tried both.)
Am I missing something obvious?
