How to Export 3DS Max to Sketchup with Materials and Textures

I purchase a lot of models that are native to 3DS Max (typically Vray or Corona). What is the best way to export those models into SU while maintaining the materials and textures? If there is some “known limitation” what might that be?

I can get the geometry no problem via FBX/OBJ native export out of 3DS and sometimes a texture if I use SimLab’s exporter. But generally I’m having a REALLY hard time getting models from 3DS to SU without spending hours trying to remap everything.
