Despite considerable beta testing, there are issues that cropped up after the release of ZBrush 2021.6.2.
- Sculpting brush may stop working. It has been discovered that if you store an Undo History point by Ctrl+clicking on an undo, then changing to a different model or project can cause any brush that uses Fast Samples to stop working. There are two ways to work around this until a fix can be released:
- Turn off Brush >> Samples >> Fast Samples
- Store a new Undo History point by Ctrl+clicking on an undo and then Ctrl+click on that stored point to immediately remove it again.
