It appears that when saving a SolidWorks part that has a Maxwell material assigned, that assignment is lost as part of the save/rebuild process. The material itself is still part of the file, but the body(ies) that it was assigned to is lost. The Maxwell material assigned in SW is part of the materials listed in Studio, but that material is no longer assigned to anything. If the material is re-assigned then Studio will see the proper assignments, until the part is saved again.

SW 2007 SP4, Windows XP, Mawell Render 1.5.1.
