Camera Grid is a viewport overlay add-on for Blender that displays all cameras in a scene as an interactive grid for quick switching and selection.
The overlay offers two display modes: simple solid tiles or cached viewport thumbnails. Camera switching works through click, drag, scroll wheel, or arrow keys, and a right-click drag lets you paint-select multiple cameras at once. For scenes with many cameras, the grid is scrollable with a scrollbar and edge-scrolling. Layout options cover adjustable size, alignment, rows, and display settings, and version 1.2.0 added support for multiple simultaneous viewports.
Camera Grid is compatible with Blender 5.1 and newer and is released under the GNU General Public License v3.0 or later. It is written entirely in Python, and the source is available on the developer's GitHub, where it can also be built from source using Blender's extension build command.
