How to fix a slightly distorted uv


Recommended Posts

Helloo
 

So I have this little uv issue happening only around the nose. This is all because I was using 3 differents faces that I morph between each others with VDBs;
convert back to polygons and then transfer back the uvs from one of the 3 faces with xyzdist() and primuv(). Atribute transfer was worse.
I didn't have a choice to use VDBs because the point count is different between faces. 
 

I tried uvbrush and uvsmooth SOP but no luck

Any ideas?

what I thought of doing was trying to blend the three set of UVs (one per face) at the same time the faces blend from one to the next. But I have no idea how to do it, and because the point count is changing, I don't think it will work
