Bijou, thanks, I'll try that. Mateo, I did that - I hacked the usemtl to g (with V2 - the lashes - upperbrows - etc. are a bear to isolate) - and that works well enough - into MFM - save - hack back to one g - morph did not work. What I think happened: the verts were listed differently on save - to get the groups all together is my guess. Maybe if I make it one group in RDS/VM before the save - it will leave the order alone. At least with the upbrows and lashes - there is not the problem of duplicated verts at the new seams - those mesh are not linked anyway. The mouth, lacramal, nostril - may be a problem - they are linked - once they are duplicated - I don't know how to get those verts welded, but just those verts. I do have my preferred weld range = 0.0 pts - but hunting those guys down one-by-one is not worth it and you never know if there are others in there that must be left alone.
