I am working on a large project that uses many blender files which consist of catagories such as models, animations, etc. Does anyone know of an open source program that would let me check blender files in and out to keep up with what version the file is in? I have been using the nomenclature of let’s say, props_glassbowl_001.blend, where the _001 is the version. If I make a major change, I want to be able to keep the current version, and have a new version of the new changes. The reason I want this automated, is that other people may be handling this same file, and I need them to know that the file is Checked out already.
