Hi...
Are you exporting straight from CC3 to Maya without taking the character into other tools first? Also are you exporting the standard base or are you using GameBase?
Providing you export using the Maya pre-set your results should be the same each time. If they are differing that would normally indicate you have changed your settings or your workflow in some way.
So we can check, please post a screenshot showing your FBX Export panel including the Advanced panel.
