This operator is a combined version of mask expand and mask by normal from the sculpt branch. It can be used to quickly isolate parts of a model based on topology or curvature.
- Shift + A starts the operator in topology mode from the active vertex
- Shift + Alt + A starts the operator in curvature mode from the active vertex
Auto pivot position and mask invert are on by default. When the mask filter is merged the code that smooths the final mask can be enabled.
