Blender can bake lot of stuff.

Didn't dig it , but you could bake SSAO and lightmap both directly in same texture ?

 

Another LE3 point :

Making BSP in LE3 and placing lights in Leadwerks 3, make that these Lights that will be used in static BSP lightmapping, and they will work as dynamic lights on models when running the game.

Importing lightmapping from external programs, make that you loose the light information, so you won't have the dynamic lights.
