Quote - The problem I'm running into is when sub-dividing the mesh to generate the hi-res mesh...

    * vertices get re-ordered.

    * polygons get re-ordered (and thus, the uv-polygons)

    * 'slight' differences in the final positions of some vertices - likely due to the 3D software I'm using to do the sub-divide, but possibly also due to some 'options' (vertex weighting) of that process.

I think odf made some custom tools specifically for subdividing from the lo to hi Antonia. I seem to remember that MJ had problems converting his UVs from lo to hi, and that odf fixed it. You might try sending a site mail to odf for more info on this.

Quote - Anyone have any comments for/against leaving Antonia mapping on the inner mouth parts?

I see no problems with that. Sounds like the best way to resolve the issue. Does your process leave the hi version morph compatible with the standard Antonia hi res?

Quote - BTW, I've also managed to remove a lot / most of this texture-stretching/distortion...

**Great work. I'm very impressed! **:thumbupboth:
