Raven, I did uncheck all the Poser import options. (Oops, including the "Make polygon normals consistent" — is that important? Should that always be left checked?) I think I might have messed up a bit with the export from 3D Exploration. There's a "Geometry Transform" option in the Save As dialog, that allows the exported object to be scaled and positioned... hold on... I think I got it. Looking at the dialog again, I had those exports set at "Fit size to 1 unit" and "Position center". Which is exactly what happened. I'll have another go and see what happens with different settings... (Is anyone else out there still using 3D Exploration?)
