In Retopology tool, using UV maps for guide.

[gurkiratsinghchahal]

I see that retopology tool works fine on separated faces only when you separate the geometry into simpler forms, like say separating the object into faces based on UV that I has created and then running the retopology tool. Could someone guide me to write a code so I can perform such thing using code, because I see it is not built in retopology function. 

Thanks it would be great.

Try breaking your problem up into smaller problems. 

- Search to see if someone has already answered separate by UV shell

- See if there is a way to list faces by UV shell
- Chip off those shells
- Run your retpo on each of those shells
- Recombine

It strikes me that you will probably run into some pretty serious edge adjacency issues when trying to recombine your mesh, so it might be worth considering how you could convert from UV borders to hard edges, then preserve hard edges in your retopo operation.
