Zbrush 3.1 OBJ Export Problem

ZBrush Usage Questions
#1

Hi all,
When I export a particular mesh from Zbrush, the resulting mesh gets stretched out over a much longer distance, with all the vertices on two flat planes on either end. I’ve not had this problem with any other meshes, just this one. I’m importing the OBJ into Max 2008 but I’ve exported it from Zbrush and reimported it straight back in and get the same result, so the problem seems to lie in Zbrush.

Any ideas would be greatly appreciated, I need a solution urgently!

A picture would help to show the problem you’re having. Sometimes issues of this sort are caused by scaling. You could try pressing Tool>Deformation>Unify before exporting (save a backup of your model first).

Sorry, should have posted some pics in the first place!

I’d already tried Unify but it didn’t resolve the problem. Here is what is happening:

A couple of things to try:
Use Transpose Master to create a TPoseMesh, then immediately transfer the ‘pose’ back in to the original. I know there are no subtools but this may solve the issue.
Also, before exporting press Tool>Masking>Clear to make absolutely sure none of your mesh is masked.

#5

No luck with either of those I’m afraid. The Transpose Master just exploded the mesh.

I did a few tests though; importing a box from Max 2008 and then exporting it from Zbrush always results in the same problem; its only if I edit the vertices in Max before exporting that it will export from Zbrush correctly.

Yeah I came across that post when searching earlier; its not really the same problem I don’t think, I can’t get past step one because the mesh breaks as soon as I export it out of zbrush, so anything I import back in from Max would still be wrong I think.

Think its best just to start again!

Thaks for your help.

Another thing to try:
Select your mesh, set to its lowest subdiv level and press the Tool:Make Polymesh 3D button. Try exporting this new mesh to see if you have the same problems. To get back your polypainting & subdivision levels do this:

  1. Select the new polymesh & divide to the same number of levels as the original.
  2. Append the original as a new subtool. Set to its highest subdiv level.
  3. Select the new polymesh, go to highest subdiv level and store a morph target.
  4. Press Toll>SubTool>Project All. Detail and polypainting should be transferred. Any spikes can be erased using the morph brush.

The polymesh has the same problem once exported. I’m not sure what has caused this problem but it seems like the model was doomed the moment the low poly box left Max!

Cheers.
