Hi,

after a few more hours passed on this little problem, no solution found for now.

It seems that there is a "bug" which appeared in the geometry of the face, and i can't fix it with all the tools i have tried. I don't think it's coming from the tongue but really from the corner of the mouth (the upper and lower jaw were hidden on the pictures i putted here).

Maybe i'll need some external expertise to fix that thing, someone here would be kind enough to have a look of it in poser ? Or it could be a one hour payed job.

The fact is i would be able to clean that if it was showing in preview, but there is really no way make the "bug" appear in preview mode.

Another path : maybe it's due to a poser smoothing geometries algo ?
