Any lightmapping tool (external)?

Unity Engine
1

Because, the Unity internal lightmapping feature is not working for me, I would like to know if are there any external tool for creating static lightmaps and import them in Unity.
Until now I have used Giles, a good old tool, but it is pretty limited and it is not compatible with .fbx format.
Do you know any lightmapping external tool good enough?
(Please I mean a cheap and affordable tool. ;))

Thanks in advance.
