Hey guys… well I’m having a problem with exporting my Geometry with GoZ to maya… an error pops up in Maya when I press GoZ… I also tried to export an obj. out of Zbrush but maya still wont read it… I checked the settings in the Export dropdown and my scale and XYZ offsets are set to “nan”… when I change their settings to 1 and try to export again it still wont work… Can some one please help me… I have Zbrush 3.2 OSX
and Maya 2009…
Thanks
Oh wow, I just helped a guy with this yesterday. I had never heard of nan before, and here it is again! He gave me his file for download, and here’s what fixed it on my end.
My theory is that nan on an axis will place all verts on that plane. So if xyz offset is all set to nan, then all the verts in the whole model will be exported on the origin in a single, centered point in space…
All I did was drag the xy and z offsets away from center on the slider, and then back to center. It changed the “nan” to 0 on all of them, and I made sure the scale was at 1. Then it exported perfectly.
Please let me know if this works, I would like to figure out what causes it.
it worked Thanks!!!
maybe I did something wrong the first time, because I remember setting the export scale and XYZ to 1 and it didnt want to work at first… After I read your response I tried it again, (scale and XYZ set to 1) and it worked…
Thank you:D 
I’ve had the same problem (I think). I sent a question to Pixology via the ticket service.
This was my original question:
Sometimes a tool wil not export properly as a 3D model, either with the tool:GoZ or tool:export function.
I found that the scale and offset in tool:export submenu is set to ‘nan’.
Is there a way to prevent this from happening?
This was the answer
There is no way to prevent this. I would recommend saving your tool with all the subtools in place without any sculpt on it for referencing the Export Scale and Offset of any tool. If this nan shows up again you can just type in the correct scale and offset then export and reimport on the same model. That will solve that issue.
We will be addressing this in the next update.
