Why we like it

Simple Camera Match earns its spot in the blender_extensions library for keeping its whole workflow inside the camera viewport, right down to a dedicated undo/redo stack for drawing that stays clear of Blender's global undo tree.

What is Simple Camera Match?

Simple Camera Match is a lightweight Blender add-on for camera reconstruction and perspective matching. You draw X, Y, and Z vanishing lines directly in the camera viewport over a background image, and the add-on solves the camera's focal length, location, and rotation automatically in real time.

The entire process happens in the camera viewport's 2D space with real-time visual feedback. A horizon constraint lets you drag horizon handles to fine-tune the camera's pitch. Keyboard shortcuts switch between axes: press 1 for the X axis (red) and 2 for the Y axis (green). Hover over a line's endpoint and press X to delete it, or press Esc or right-click to exit drawing mode at any time.

Drawing operations use their own independent undo/redo stack, kept separate from Blender's global undo tree. Simple Camera Match is released under the GNU General Public License v3.0 or later, runs on Blender 4.2 LTS and newer, and ships with builds for Windows, macOS, and Linux.

Who is Simple Camera Match best for?

Simple Camera Match is best for blender users solving camera focal length, location, and rotation to match perspective against a background image.

How much does Simple Camera Match cost?

Simple Camera Match is completely free to download and use.

Frequently asked questions

Does Simple Camera Match work with Blender 4.2?

Simple Camera Match is compatible with Blender 4.2 LTS and newer, so any release from 4.2 onward should run it. You can add it by dragging and dropping the extension into Blender, or by downloading the package and installing it from disk through Blender's extensions preferences. If you're on an older release, you would need to update Blender first, since versions before 4.2 fall outside the stated compatibility range. The developer's GitHub page and the Blender extensions listing carry the current details.

What operating systems does Simple Camera Match support?

Simple Camera Match ships with builds for Windows on both ARM64 and x64, macOS on both ARM64 and x64, and Linux on x64. That covers Apple Silicon and Intel Macs as well as ARM and standard Windows machines. The add-on installs the same way across platforms: drag and drop the package into Blender, or install it from disk via the extensions preferences. For the exact package and any platform-specific notes, check the developer's GitHub page or the Blender extensions listing.

How do I switch axes and edit lines while drawing in Simple Camera Match?

Simple Camera Match uses keyboard shortcuts while you draw. Press 1 (or numpad 1) to switch to the X axis, shown in red, and press 2 (or numpad 2) to switch to the Y axis, shown in green. To remove a line, hover over one of its endpoints until it highlights, then press X. You can leave drawing mode at any time by pressing Esc or clicking the right mouse button. All of this happens inside the camera viewport's 2D space with real-time visual feedback.

How does Simple Camera Match adjust the camera's pitch?

Simple Camera Match includes a horizon constraint for adjusting the camera's pitch. With the horizon system active, you can drag the horizon handles directly to fine-tune the pitch angle. This works alongside the vanishing-line drawing that solves the camera's focal length, location, and rotation from a background image reference. The whole process runs in real time inside the camera viewport, so adjustments show immediately. For more on the feature set, see the developer's GitHub page.

Is Simple Camera Match free to use?

Simple Camera Match is listed as free in this catalog and is released under the GNU General Public License v3.0 or later. That license governs how you can use, modify, and redistribute the add-on, and it also means the source code is available. For the current licensing terms and the code itself, visit the developer's GitHub page. Because licensing can change over time, it's worth confirming the latest details there before relying on it in a commercial project.
