This shows the ZScript Window at the bottom of the UI. In ZBrush, press the ZScript>Load button and select the Change_FBX_AutoScale.zsc file.Copy the Change_FBX_AutoScale.zsc file to your ZBrush 4R7\ZScripts folder so you can find it again should you need it.Open any folder that may have been created and find the Change_FBX_AutoScale.zsc file.Download the file to your Desktop and unzip it.

In the meantime, the script below will solve your problem. The FBX plugin doesn’t include a way to turn off auto-scaling at the moment but I will consider adding it in an update. So if you are mixing GoZ and FBX you could run into scaling problems. GoZ doesn’t use auto-scaling (although there has been some discussion whether it should).

It only affects how your model looks in ZBrush - the Transpose line will still give the correct measurements (in generic units equivalent to whatever your export units were) and the model will be correctly scaled on export. That’s why if you import an OBJ into the PolyMesh3D Star it will be auto-scaled. ZBrush’s sculpting brushes and other features work best when the model is a specific size.
