A powerful saving tool.
Go to Blender preferences, Add-ons, then click Install... and choose the zip file.
Set your Base Folder in the PowerSave preferences. Your powersaved blends go there.
After installation you have a new icon in the 3D view top bar.
It is red, when your file is unsaved, and turns green, when your file is saved.
Gray means saved, but with unsaved changes. There are color options in the preferences.
Clicking the icon opens the PowerSave panel.
The PowerSave button will save your file using the project name given in the text field,
or a timestamp (configurable in the preferences), and saves it to your Base Folder.
If you use PowerSave with a previously saved file, it will use its location.
If the file already exists, clicking PowerSave will do an incremental save, which adds a number at the end of the file name.
You can use slash to create a directory within your Base Folder or current directory.
The arrow icons open the previous/next iteration of your project.
The Autosave Interval is how many minutes to wait between autosaves.
The Autosave Format lets you choose one of five options:
Overwrite- Autosave over the original fileExtension- Autosave with the ".blend.autosave" extensionSuffix- Autosave with the "_autosave" suffixFolder- Autosave in the "autosave" subfolderCustom- Autosave with a custom folder and file name
When using Custom, it uses the Autosave Folder and Autosave Name you set in the PowerSave preferences.
The Autosave Folder can use both absolute and relative paths.
The Autosave Name replaces {name} with the file name without extension.
If you open a file and there is a newer autosave available, you will be prompted to open it.
If you click OK on that prompt, it will open the autosave and save it as an increment of your original file.
