Hey guys I really need some help with this. I must just have a
misunderstanding of how to manipulate things.
To show exactly what I am doing I want to manipulate the LeapMotion handmodels
offered with their SDK.
The hand models come as FBX format. I have opened it in 3DS max and saved them
as a osgb file with the OpenSceneGraph Max Exporter.
Then if I run a Node Traversal on the hand I get a list of all the
MatrixTransform nodes and thier names.
So to test it I am trying to use a callback class to simply move one section of
the hand. I do an if conditional like:
if(node.getName() == "L_PinkyD")
Then I use a matrix to setMatrix and apply it to the node.
If I attach axes to each transform node I can see that the specific axis is
moved. But the hand model itself remains unchanged. Am I suppose to be
accessing it with osgAnimationBones? because I can't see any bones when i do a
ClassName() and LibraryName() on the nodes. Only matrix transforms. In fact
this is the print out of the hand model I get in my log file:

Do I need to rig and skin the model programatically? Beause I can see the bones
in 3ds Max.. if I move a bone in there the model moves with the bone. But in
OSG I just cant get the hand models to change with any update...
HELP! Ill provide more information if its needed... Ive tried to be as specific
as I can. Thank yoU!
