Mouselook Navigation is a free addon that attempts to improve upon Blender’s 3D viewport navigation and provide some neat features from other applications (e.g. ZBrush’s tablet/stylus-friendly navigation).
Originally created for Blender 2.7, it’s now ported to Blender 2.8 (and all new development will be happening in the Blender 2.8 version)
- ZBrush mode - mostly useful for tablet users, since it allows to use the same mouse button both for painting/sculpting and for navigation (depending on whether you clicked on geometry or on background)
- Easy switching between navigation modes without exiting the operator
- Changes to viewport can be cancelled from any mode
- FPS-like movement is available in all navigation modes
- Crosshair is visible in all modes and has a different look when obscured
- Option to more easily prevent accidental viewport rotation in Ortho projection
- Different turntable/trackball algorithms and different fly mode (more FPS-like)
- I cannot understand how to implement Blender’s trackball behavior in python. I’ve tried my best to translate the corresponding C code, but the result still behaves very weirdly.
- Other known issues (see the documentation for the full list) are caused by the incompleteness of Blender’s API, so currently it’s beyond my abilities to properly fix them.
