Same here
Carrara 7 Pro export the geometry only
The point is that animations seem to be the most critical issue
UltimeUnwrap3d for example can export static models but animations are messy
An alternative could be Messiah 4.0 , they are developing also the FBX exporter

I can not really understand why all the new engines support FBX or Collada only
Ok in principle it may be reasonable but they should be aware of these problems

I had to quit, for the time being ; with Unity3d
Ecxellent engine but it is of no use if you can not import models
