Blendgit is an addon for Blender 2.7x <http://www.blender.org/> that lets you keep track of multiple versions of a .blend file using the Git <http://git-scm.com/> version-control system. Blender itself lets you keep older versions of a file each time you save, up to a maximum of 32; using version control extends this to unlimited versions, and also lets you attach a comment to each one to remind yourself why it was saved. Once you have installed the addon and enabled it for the current document, you will see an extra submenu at the bottom of your “File” menu, entitled “Version Control”: this contains two items, “Load Version...” and “Save Version...”. Selecting “Save Version...” will display a popup letting you enter a comment to be associated with this version; clicking “OK” will save the current document, along with any external files it depends on (fonts, images, libraries, sounds) into the repository and attach the comment. If your document is called “foo.blend”, then the repository directory will be called “foo.blend.git”. Note that the document has to have been saved at least once (i.e. it cannot be untitled) before the repository can be created, because it takes its name from the .blend file. Having saved a version of the document, you can reload that version at any subsequent time by selecting “Load Version...”: this will display a list of the comments associated with all the versions you previously saved, from which you can select one and click “OK” to reload that version. This will WIPE OUT THE COPY OF THE DOCUMENT YOU WERE WORKING ON (both in-memory and on-disk) ALONG WITH ITS DEPENDENCIES, so you may want to make sure that was also saved in the repository before loading the older version. Blender doesn’t seem to allow for attaching “Cancel” buttons to popup dialogs; however, you can dismiss the load and save dialogs without performing any action by pressing the Escape key.
