Re: Zbrush and vertex IDs
For the UV's make sure in Zbrush in the Export options in the Tool Panel you have 'Txr' turned on. It won't export UV's with that turned off.

Re: Zbrush and vertex IDs
Are you sure is the vertex order that is changing? or just the samples order? Andy's description and solution seems to be the best one. I would try to export from softimage as obj and import again to softimage. The export this new mesh and replace the base mesh in Zbrush. If this is too much, maybe you could try to fix the UVs manually http://vimeo.com/67783125 On Sat, Dec 6, 2014 at 10:35 AM, Sebastien Sterling < sebastien.sterl...@gmail.com> wrote: > Might it be a problem with the app link ? > > i notice it to happen with layers as well. > > On 6 December 2014 at 14:41, Andy Goehler > wrote: > >> I’ve noticed this behavior post Softimage 2010 releases.

Re: Zbrush and vertex IDs
Might it be a problem with the app link ? i notice it to happen with layers as well. On 6 December 2014 at 14:41, Andy Goehler wrote: > I’ve noticed this behavior post Softimage 2010 releases.

Re: Zbrush and vertex IDs
I’ve noticed this behavior post Softimage 2010 releases. Where with the OBJ exports the vertex order is not preserved. It caused us many headaches and countless numbers of redoing UVs. Like you I have nothing reproduce able, however your chances of the bug increases when you mirrored the mesh before. It’s odd — I’ve advised my team to export to .OBJ and reimport before rigging and UVing. It’s a Softimage bug, not ZBrush.

Zbrush and vertex IDs
Ive noticed now a couple of times when sending a mesh back into sofrimage, that the uv's get erased or that the vertex order, or ID is different, often this seems to happen regardless of what degree of manipulation i want to effect. I can't seem to find a reocuring reproducible source for this, with the possible exception of dividing the mesh, adding a sub div level, something you can do in mudbox without any issues. *Is there some guard, some box I can tick to tell zBrush to preserve vertex order ? or at the very least will prompt me if a perticular manipulation is going to break it ?* Many thanks and a good weekend to you ! - Seb
