Is it ok to use Blender's 2.62 FBX exporter for skeletal mesh?

You need to bake normalmaps using xNormal to use the improved workflow... I can never get xNormal to work right without major artifacts.

Well you must be able to export tangents and binormals and Blender can't do that AFAIK. So maybe there are other ways to do so
