Unwanted reverting UVs

ZBrush Usage Questions
#1

OK, this may sound a little convoluted but it’s pretty straight forward. I hope someone can point out a fix for my problem or at least confirm that it is a bug.

My work-flow is:


  • Import cage of object.
  • Select the Suv button, just in case.
  • S-Divide model 10 times ( to about 4.8 million) to get desired rez.
  • Deform the model and add detail to get final object.
This is where my work-flow may differ from normal.


  • Export S-div level 6 mack into Maya and relax the UVs as ZB’s “Suv” button does’nt seem to work.
  • Inport the UV edited file back into ZB at S-div level 6.
  • Uv Check the model and all is fine. The new UVs carried across fine.
  • Export S-Div level 6 mesh as OBJ.
  • Export displacment map useing Multi Displacement 3 and bump map using the Displacement map generater.
  • Check Uvs again and they have reverted to orginal UVs.
Also, when I thought I had got the UVs working fine I’ll save the Zmodel. Restart and check… the UVs are back to the origenal layout. :confused:

There are 4 SubTools in the file with a combined poly count of 9.4 million polygons.

This computer’s spec is Dual-Core AMD Opteron 2.20 GHz, 4 GB RAM, Windows XP Profesional x64 Edition

Any help would be usefull. Thanks

UV’s can only be updated at level 1. That’s where your problem is coming from.

Thanks Aurick,

So it’s just a case of deleting lower SubDs than the one you want to import the UVs from.
