Pixologic Release SmoothGroup Import Plugin for 3.5R3
This plugin is designed by marcus_civis for those who like to work with smoothing groups in Max or an app that supports them. It will import an OBJ into ZBrush and automatically crease the borders of any smoothing groups. If there are regular groups these are unaffected.
You can grab the update from the ZBrush Download Center
Thanks to Josh for the heads up!
