thank for your reply…
i have delete history before export~
after all , i try this way and got a better UV than before.
- after finish my sculpt, i export my lowest level mesh to OBJ.
- export hightest level mesh to OBJ WITHOUT UV.
- make more relax in the lowest mesh (use UVLayout), especially the RED part. save file.
- import the OBJ to Mudbox that i just export in UVLayout. SubD it to the highest Level ( i have check smooth UVs.
- import hightest level OBJ ( that’s step 2 file). Done!
finally , i check the hightest level UV in UVLayout, i got a better UV than without doing these steps.
i’m not sure is that correct, but that’s the only one way i can do :sad:
