Auto Active Camera Switcher is a Blender add-on from Yamato3D-3dnchu.com- that automatically sets the selected camera as the active camera in the scene. Selecting a camera makes it the active one, without extra menus or clicks.
The feature can be enabled or disabled from the Sidebar under the View tab. A camera icon added to the top of the viewport lets you toggle the auto-switch function quickly, and the default state can be configured in the add-on's preferences.
Written entirely in Python, it requires no special permissions and is compatible with Blender 4.2 LTS and newer. It's distributed under the GNU General Public License v3.0 or later. Version 1.0.2 brought code corrections. On the Blender Extensions platform it holds a popularity rank of around 245.
