Why?
With the combination of FaceGroup and Relax using Inflate can act as an extrude on the same surface.
Loops can help to add extra edges around an isolated area, Mask or a FaceGroup to keep maintaining the edge sharp and help with mask selection.
In this example I managed to make multiple loops by shrinking a mask and creating FaceGroups then Auto Retopo and using the Relax filter.
Where in the UI?
The FaceGroup palette already has an option for relax, Loops can be included in there. This can also apply to an isolated FaceGroup.
Sustitution for Panel Loops
Having an option in the Mask and FaceGroup menu for applying the carv-extract-split directly into the same geometry will be more than enogh, even superior to Zbrush
This workflow is one of the most advance and powerfull ways to create in Zbrush. I’m sharing this video of Sculptor Daniel Bell using this technique for making a complete tennis shoe.
This feature will be amazing to have. Thank you for your hard work keep it going!
