This is an update of the Smooth Group Import / Crease Groups plugin that will work with ZBrush 2018 (Windows and MacOSX).
- Unzip the file to your Desktop.
- Open any folder created by the unzipping and find the SmoothGroupImport_2018.zsc file and SmoothGroupData folder.
- Copy the SmoothGroupImport_2018.zsc file and SmoothGroupData folder to the ZBrush 2018\ZStartup\ZPlugs64 folder.
Restart ZBrush and you should have a new Crease Groups sub-palette in the Zplugin palette. This has two buttons:
Crease Smooth Groups
Use this button to import an OBJ with smoothing groups. The group borders will be creased allowing you to control the way the model is smoothed when you add subdivision levels. If there are also polygroups in the file these will be preserved. If there are no polygroups then the smooth groups will also be converted to polygroups, making selection easy.
Use this button to import an OBJ with regular polygroups. The group borders will be creased allowing you to control the way the model is smoothed when you add subdivision levels. The polygroups will be preserved making selection easy.
Additionally both buttons will import polypaint and masking data if available and the OBJ was exported from ZBrush. Note that this will only work if the OBJ was exported from ZBrush and the data written in a block starting with #MRGB . This is not part of the OBJ specification and may not have been implemented by programs other than ZBrush.
