I’ve heard about that tool. But to be honest, the pivot thing doesn’t bother me as much as mapping everything for the lightmass… This is by far the most time consuming and boring task for me right now.
There is no material converter yet. My tip is to create a good base material with all the parameters you need and then just instantiate it. Changing the diffuse, specular and normal maps plus minor parameter tweaks will be pretty much the only effort you’ll need to replicate everything fast.
