Thanks EnglishBob, I did that, and it didn't fix my problem, but it fixed the part that was puzzling me. The other part of my problem was just stupidity on my part. I exported in 3DMF the first time, and when the alterations didn't import again properly, I went and exported the alterations of the original 3DMF file as a 3DS file, and the 3DS files do wierd thing with x/y switching, so I couldn't cross import like that. Once I had removed the upload changes, it was obvious what I had done. My head morph was lying on the ground exactly one person hieght from the figure's feet, and the morph instead of pulling the head down, also now pulled it sideways and back, and rotated it, and.... I tried fixing the wonky file by running it through UV mappers's switch z and y function, and that rotated it upside down. :/ I think I'm going to start again from scratch, unless anyone knows a mac utility that will switch axis and positive/negative co-ordinates on demand.
