In some of the online docs, it would seem that a specific # of bones and
bone names have
to be used. Somewhat surprising, as I had thought that any mesh with any
armature should
naturally be importable (i.e., if you wanted to build a robot arm with 3
bones) into the
viewer.

Here is another oddity:

 in the most recent version of Blender 2.59, if you import LL's supplied
simplebot.dae file, there is
no armature - it isn't there, only a mesh. If you try in Blender 2.49b
(which according to the
simplebot.dae header was used for export using Collada 1.4.0), I
couldn't locate the armature in
there either although I confess to perhaps not fully knowing the
interface---the gui for Blender
has changed dramatically since 2.49.

Anyway, I agree that this seems not to be an opensim issue so maybe we
can take it offline to see if we
can investigate further to figure out what is, and is not, possible. I
was thinking that a basic solution
to the Evolver avatar problem was to import the armature (from simplebot
which is known to
import into the viewer) and then parent this bone structure to the
Evolver mesh. That would be
great if only the armature could be obtained in Blender...
