Shape Key Collections

0 ratings

Organizing shape keys is a nightmare because you just cannot give them structure due to the lack of any such mechanism in native Blender.

This is where Shape Key Collections saves the day and allows for full control over your shape keys. Bring structure to the chaos, a folder structure, that is.

With this new management system you can rename and organize which shape keys go in which folder collection, including the benefit of subfolders for full detail of your many shape keys.

The Master Shape Keys addon contains this addon in its full version -

In comparison to the original-unorganized list, this is a must.

Split Keys

Put together up to three shape keys and display each value in one place. This allows you to group related shape keys for easier management and control over your mesh. An example would be the left and right eyebrow as shape key 1 and 2, while the 3-rd would be both of them together.


Are there tutorials?

  • Of course, check the Documentation section below.

The .zip doesn’t install in Blender

  • Please un-zip the archive and install the .py script.

How do I activate an addon?

How many shape keys can I have on a model?

  • You can have as many as your computer would allow you (performance wise). During testing the addon slowed down at around 1000 shape keys. Most of that slowness was only related to moving the shape keys up and down, and changing folders, not in regards to the rest of Blender.

I have v2 of the addon, will I lose my previous folder structures?

  • You shouldn’t lose anything. But even if something goes wrong, reverting to v2 of the addon would bring your structure back.

How can I get more control over my shape keys?

Will this addon work on another computer?

  • So long as the computer has the addon and the same Blender version, the Collections will work.



Add a new shape key or remove the active shape key or folder. If you remove an open folder, its children will become a child of the folder the now-removed folder was a child of (they will step down in the hierarchy). If you remove a closed folder, the folder and anything inside of it will be removed

Rearrange the order of shape keys or folders. An item may not be moved outside of a folder it belongs to, or into a folder it doesn’t belong to

Add Folder
Creates a ‘Folder’ object inside the list of shape keys, which can have shape keys or other folders put into them to create a structured hierarchy

Folder Toggle
Open and close the folder. Closing a folder hides everything inside of it, for a more tidy UI

Drop-down Menu

When a shape key is selected, this works exactly the same as New Shape Key from Mix. When a folder is selected, this will duplicate the folder and any folders or shape keys inside of it

Track Applied Keys
When Applying or Saving modifiers as shape keys, Track Applied Keys must first be enabled, or the new shape keys will not be added. First, enable tracking and the UI will be greyed out. Second, Save or Apply whatever modifiers you wish. Third, disable Tracking and the new shape keys will appear

Open/Close Folders
Opens or closes all folders in the object’s shape key list


The name of the shape key (like in default Blender) or folder. You are safe to rename folders at any time, even if it has things inside it

The folder, or ‘parent’ of the active shape key or folder. Items that belong to a folder are bound to stay within that folder, and will move with the folder if the folder is moved around.

The value of the shape key (like in default Blender).
