Import Autodesk 3ds Max humanoid to unity game

I have an Autodesk 3ds Max animated humanoid into 3D Studio Max into Unity 3D Game Element. I want it converted to unity with all of it's shaders and skin. The model is already animated and just needs to be exported to FBX and imported into unity. The issue is that I am unable to export it properly with the skins and humanoid. This is an urgent project but should be done well.
