Also .OBJs that have values with exponents won't load in 5.5. This is pretty common with pro modelers and they also worksin 501. I know you just want 5.5 to work correctly (I do too!) but UVMapper does fix all the .obj problems I've found but you can also (well almost always) load into 501 and save, and load that into 5.5. Here's looking forward to another 5.5 update; Dan
