Procedures
To use adaptive subdivision:
- Edit an object with the HSDS modifier.
- Choose Add Detail or Remove Detail, depending which operation you want to perform.
- Set the desired amount of detail with one of the presets or by specifying custom Length and Angle settings.
- Click OK to perform the specified operation.
The detail addition or removal is performed, and you're returned to the HSDS modifier. Depending on whether you removed or added detail, the highest level of detail is decremented or incremented by 1.
