well ...i gess it's a good solution but it would be helpful for the model i will create after two years from now ......(;D) .... actually when i searched about somethings that may cause this problem ... i found that the problem is about exporting the "bindpose" in the right way .... may be i missed some option while exporting ... or the animation must be done using some special way .......... i don't really know

any way, thank U very much for Ur reply

FBX changes every release, and it has known bugs in each version. It seems as if, for some reason, Autodesk just can't get it right. You'd think they'd solicit some number of test models from different real-life studios (for film and games), and verify that they transfer correctly with each file format with each version, but as far as I can tell, that doesn't happen.

First, you need to apply the reset xform modifier before you apply Physique or the Skin modifier. You also need to remove scale from all your bones, before binding to the skin. If you haven't, this means that you have to un-bind your skeleton/modifier, reset the mesh and the skeleton bones, and then re-bind/re-weight the mesh. Yeah, that's a drag.

Second, you need to experiment with the different parameters, export parameters like "make Y up," scaling, etc as well as import parameters like "flip winding," scaling or rotation.

Third, if you still can't get it to work, when I got annoyed that it just wouldn't work, I wrote my own exporter: kW X-port. As far as I can tell, it is the least buggy, most complete way to get animated characters from 3ds Max 9/2008/2009 into XNA Game Studio. Coulped with kW Animation it actually makes for a useful animation system. As far as I can tell, people using FBX and/or the Skinning Sample end up running into a lot more limitations than I've run into with those libraries. However, kW Animation is not for the beginner -- it doesn't come with tutorials or hand-holding.

This happens to everybody that does fbx exports, I can just say that you have a long ride of trial and error in front of you. I would recommend you to start with just a simple mech, with nothing special on it. Try to export, add bones, export, add skinn, export etc. by doing it step by step, you can find what's causing the problem. Good luck, you need it!
