Why we like it

Camera Undo fills a specific gap: Blender's standard undo treats camera moves as part of the same history as animation and object edits. This addon gives each camera its own transform history, echoing the 'ctrl z' camera behaviour available in Maya. It is GPL licensed and lists compatibility with Blender 2.8 through 3.4.

What is Camera Undo?

Camera Undo brings per-camera undo and redo to Blender, mirroring the 'ctrl z' behaviour for camera location found in Maya and other software. Press Ctrl+Alt+Z to undo a camera transform and Ctrl+Alt+Shift+Z to redo it, with a separate history kept for each camera.

The addon keeps camera transform history apart from Blender's standard undo. If you move a camera several times and then animate a rig or move other objects, you can reselect the camera and step back through its transform changes without touching the rest of your work, where normal undo would reverse the animation or object movements instead.

Because Blender cannot report whether you are actively grabbing the camera or have set it in place, the addon saves a transform only after it stays unchanged for a set number of seconds. This threshold defaults to 1.5 seconds and can be edited in the addon preferences. Documentation is included.

Who is Camera Undo best for?

Camera Undo is best for blender users who want to undo and redo camera moves independently of the rest of their scene history.

How much does Camera Undo cost?

Camera Undo is completely free to download and use.

Frequently asked questions

Which Blender versions does Camera Undo support?

Camera Undo lists compatibility with a wide range of Blender releases, from 2.8 through 3.4, including 2.81, 2.82, 2.83, 2.9, 2.91, 2.92, 2.93, 3.0, 3.1, 3.2, 3.3 and 3.4. If you are running one of these versions, the addon is intended to work. For newer Blender releases beyond this range, check the developer's page for the latest details before installing.

What are the keyboard shortcuts for undoing and redoing camera moves in Camera Undo?

Camera Undo uses Ctrl+Alt+Z to undo a camera transform and Ctrl+Alt+Shift+Z to redo it. Each camera keeps its own transform history, so you select the camera you want and step back through its previous locations. This works separately from Blender's normal undo, which means you can reverse several camera moves even after you have animated a rig or moved other objects in the scene.

How does Camera Undo decide when to save a camera transform?

Camera Undo saves a camera's transform once it has stayed unchanged for a set number of seconds, because Blender cannot report whether you are still grabbing the camera or have placed it. That interval defaults to 1.5 seconds and can be changed in the addon preferences. If you grab the camera and move it again before the interval passes, that intermediate location is not stored, so a moderate value works best.

Is Camera Undo free to use?

Camera Undo is listed as free here in the catalog, and it is released under the GPL license. Licensing terms can change over time, so for the current licensing and any usage conditions it is worth checking the developer's page directly. The addon also ships with documentation, and it adds per-camera undo and redo for camera transforms in Blender through the Ctrl+Alt+Z and Ctrl+Alt+Shift+Z shortcuts.
