I'm using the sample from http://creators.xna.com/en-US/sample/skinnedmodel

I'm trying to substitute my own model from Maya, already animated.  Last week, all I did was change the load content from "dude" to "man_walking" (my model).  It worked perfectly.

A week later, I come back with the finished model and do the exact same process but it doesn't work.  It keeps giving me the error:

if (skinningData == null)
                throw new InvalidOperationException
                    ("This model does not contain a SkinningData tag.");  //here is the error every time

I've done everything I know to do.  I've exported it out of maya to an fbx with every different setting I can think of.  Nothing works.  Suggestions?

Thanks

PS - My maya models have an entire bone structure (joints, IK handles, and 100 frames of animation for my first attempt).  So there IS skinning when I export to .fbx, but for some reason XNA isn't recognizing it. 

Did you change the processor to import as a SkinnedModel instead of a regular Model?

Nope.  But if I ever meet you, I'll take you out for some beers. 

I KNEW this was going to be something simple, and sure enough it was.

Thanks a MILLION :]

:) No problem. I'm learning the ropes of the Maya-to-XNA pipeline as well, and that issue came up several times for me.
