Mouse-Look Navigation is an interface add-on that provides alternative input methods for Blender's 3D viewport. It introduces a ZBrush-style navigation system, making it easier for pen tablet users to sculpt or paint and navigate the view using the same stylus button, depending on whether the cursor is over geometry or the background.

The tool includes FPS-style camera movement available across all modes, isometric view snapping, and customizable trackball or turntable algorithms. It also features options to lock rotation in orthographic views, an adaptive crosshair, and the ability to cancel viewport changes seamlessly.
