Scale Doesn't Match - ZTL to OBJ Import/Export, ZBrush to ZBrush (solution provided!)

ZBrush Usage Questions
#61

Trybal’s works. Sweet baby Jesus thank you for figuring out that headache.

Was just freaking out because I couldn’t export something right back to my ztl without it being all out of whack.

Zbrush just amazes me sometimes. Scales not even remotely matching? Try loading a different tool and adjusting the scale on the EXPORT to import it properly.

The program is like a savant, it can do the most miraculous ****, but can’t tie it’s own damn shoelaces.

Anyways, time to go tediously reimport several subtools. :+1:

Hi to All!
I came to this forum to find the solution of this problem. I didnt. Bud i found it my self by testing Zbrush and this is the solution:

  1. open Zbrush (it need to be a clean scene)
  2. import your OBJ
  3. load your ZbrushTool
  4. go to subtool: click main layer to select it
  5. append your OBJ object

Job Done!

conclusion: you have to import OBJ first, before you load your Zbrush Tool.

I might have lost months of work because of this.

  • made a dinosaur in zbrush
  • made props for the dinosaur,
  • everything was the right scale,
  • added detail to dinosaur
  • somewhere along the way, zbrush decided to resize my dinosaur to a tiny scale and offset it.
  • now the props do not fit.

I have saved the dinosaur many many times and cannot go that far back.
I tried to resize it with xyz but cannot get it just right to fit with the props.
none of the above solutions work for me unless I’m not doing something right.

Does anyone have any ideas to save me from redoing all my work?

Working in a specific .zpr file helps. Save on a reasonable time schedule(auto save may not always decide to work at an optimal time). If you have subtools you can merge them down and still be able to separate them later. Save as another version of the file now and again so you have a starting point should something unforeseen happen.

ok… I finally resolved it.

What I had to do was pretty bizarre

I found a previous WIP ZTool where the top subtool was exporting correctly at the right scale. I checked the export options, and it was set to 1000.

So I then went back to my most recent Ztool, and set each subtool to 1000 scale and then cloned them.

I then went back and reappended each one onto the older tool and they were all correct in the right position. I double checked each one by exporting it out to max, and it was fine and working!

Long story short… Before you append a new subtool, check the scale under exports is the same as the one on the top of your stack!

Dryn, thank you! I was able to solve my model scale problem with your method. I don’t know why or how it happened, I have a WIP, say, version 011 that exports at the right scale, and then the 012 exported extremely small. But following your steps it’s all good and matching again :smiley:

Thanks!

Thank you for setting these morons straight. I come here looking for an answer about scale and OBJ file formats and have to read about Obama liberalism blah blah blah, I feel their accounts should be deactivated for bringing this BS into a thread. I am personally insulted by their comments and have a debilitating disease that forces me to live overseas due to healthcare restrictions from so much political fodder. Disgusting!

I started to have this issue today using 3DS Max and Zbrush when exporting a sculpted subtool at lowest division to Max and then importing back into ZBrush. My solution was as follows:

Upon exporting an OBJ from Max, look to the OPTIMIZE section of the OBJ Export Options and ensure that vertex, normals and texture-coord boxes are NOT checked. This can also be accomplished by switching the Preset to ZBrush. I now get a point mismatch error (I never got this before though), which ZBrush informs me it corrects. When I switch the subtool to the highest division, all the original details are retained and everything is working as intended.

One note: even though NOTHING was changed on the OBJ going from ZBrush to Max to ZBrush (I literally exported, imported, exported again), the point order error remains and gets resolved. Hopefully this can help some people experiencing the same issues.
