Hi, thanks for the responce. The thing is all the faces in my model have a bunch of seemingly random smoothing groops, so a few of them stick out, since the bordering faces have different groups. I've tried to delete them all and give them a value of 1, but after exporting and importing, the smoothing groups are the same as before. It's really annoying, the model in 3dsmax looks a bit like patch-work in some spots. Don't know if it affects how it looks in rtw, but I would like to fix it anyway. Any suggestions? I might be doing something wrong.
