Make sure component works on FBX files


I tested the component with an FBX file and the animation was imported such that each joint had a separate AnimationContentDictionary.
I need to find out if this is the case for all FBX files, and if so, combine the animations in the processor.
Also, I need to make sure the component works on fbx files.

According to my tests, it does not work on FBX files with Microsoft importer.It seems to me that Microsoft importer ignores skin weights.

It also seemed to me that its impossible to store more than one animation with the microsoft importer. This raises the question of making our own importer, but I think we should wait till XNA final.

There is an interesting post on MS forum about FBX and skin weights:http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=900417&SiteID=1

It apears that MS importer does import skin weights.

here is another interesting post by Jon Watte: https://connect.microsoft.com/feedback/ViewFeedback.aspx?FeedbackID=235605&SiteID=226

Inside the Processor for a .X mesh, I get a vertex buffer for the mesh which contains bone indices. I also get a set of Bones on the Model, each of which has an Index. Unfortunately, they don't line up; the Bones collection has more bones than the vertex buffer uses, and the indices aren't the same.I can find no way to figure out which bones are mapped by a specific mesh instance -- hence, skinning is impossible to get right. Rigid animation works, because the connection to a bone is made through the ParentBone object, not through an index.

Repro Steps1) import a skinned .X file with animation2) attempt to write a skinning routine3) realize that the "Index" parameter on the ModelBone has no correlation to the bone indices in the mesh vertex buffer

Hopefully the 1.0 fbx importer will work for skin weight importation. If not... well... I guess we all know what that means :(
