I've got a couple questions:
1) I've grabbed the sample .dae files from this website and from 3D Warehouse. Are there more Collada files around somewhere? I'm hoping to find some more complete test files. It seems the software developers are ahead of the users on this format.
2) If I am importing a Collada file, and there are entities that my software doesn't support (like IK skeletons), am I supposed to hold that data and put it into a Collada file at export? The docs seem to suggest this, but I've never heard of that done before. If this is the case, what happens if I import the geometry attached to an IK skeleton, and that geometry gets altered by the user? Won't that mess up the way in which the skeleton is bound to the geometry?
3) Will other types of geometry get added to Collada at some point? Like Nurbs, SubD's, etc?
