How to import model without it glitching?

When i try to import a 3d model i created with Autodesk Maya the vertices of the model go all over the place and parts of it like the hands are rotated and moved away from the arm randomly. The first time i imported a different model it worked just fine but now even that one does the same thing. Here are some screenshots of the model after i imported it.

Zoomed in close to the model:

Zoomed out far away from the model:

And heres what the model is supposed to look like loaded from Autodesk Maya:

Any help will be appreciated.

If you have a skinned mesh, every vertex needs to be weighted to at least one bone.
