Ah, thanks. I did some more research and found out that collada actually provides three matrices for the joint. One is the initial joint transform, the other is the global skin bind matrix, and a third is the per-joint inverse bind pose matrix.
I also found out that the world-space joint transformation can be calculated through:
initialWorldspaceJointTransform * bindPoseInverse * skinBindMatrixHow to convert this global transform into joint-space? Sorry, I suck at matrices and transformations.
I found another curiosity though:

As you can see, part of the model does show up – that leads me to believe that it’s actually the vertex influences are wrong.
