Gizmo has changed and I don’t don’t know how to return to normal one
Hi @Nataliya_Tsygankova Welcome to ZBrush Central.
You have to enable the Gizmo3D button (see image).
The latest version of ZBrush is 2020.1.4. You should upgrade to the latest version as there are numerous bug fixes and enhancements since your version and older versions are not supported. Upgrades are free to registered users.
Thank you for your help!
