Path Maker is a Blender add-on from thornydre that replaces custom tags in output paths when a render runs. Instead of typing a fixed path, you place a tag, and Path Maker swaps it for a generated string. The value can come from a single-line Python expression, a hardcoded path, or a separate Python script.
The add-on covers three places paths are set: the Output Path in the output properties panel, the Base Path on file output compositor nodes, and the filepath on collection exporters, where the Path Maker buttons are needed to enable it. A Tag Type dropdown selects how each tag resolves. For the script option, the file defines a run function that returns a string, so a value like the current Blender version can be pulled in at render time.
Path Maker can also be loaded from the command line through the --addons flag. It runs on Blender 4.2 LTS and newer, requires no special permissions, and is released under the GNU General Public License v3.0 or later.
