Library Overrides

    Note

    It is considered as experimental, and current proxy system will be kept alongside for a few releases. Automatic conversion from proxies to library overrides is not planned, there will be a manual operator to do that, but results on complex characters are not guaranteed.

    Compared to proxies, library overrides support:

    • Multiple independent overrides of a same linked data (e.g. a whole character).
    • Recursively chaining overrides (i.e. link and override overrides from another library file, etc.).

    Note

    There are still many known TODOs/issues that have to be addressed. Please check the and Phabricator main task of the project, for more details.

    You can override a single data-block from two places:

    • The Outliner (it’s in the context menu of IDs), in which case all local usages of that linked ID will be remapped to the new local override.

    Make Library Override Operator

    This one operates in the 3D View, over linked objects or local empties instantiating a linked collection (typically, a linked character). It is very similar to the Make Proxy operator, and is found in the same sub-menu Object ‣ Relations ‣ Make Library Overrides….

    Unlike the method described above, it will go through the whole hierarchy of collections and objects, and override all those needed to allow posing/animation of a character.

    Note

    Proper Collections Layout Matters

    Editing an Override

    Essentially, and override is edited the same way as a regular local data-block. You can use operators on them, edit their properties from various editors, etc.

    There are some limitations however, most notably Edit Mode is not allowed currently for override.

    In most cases, as soon as you edit a property, you can see that it’s overridden by it’s teal blue outline/background (like the yellow/green/purple colors of animated/driven ones).

    You can also animate overrides, animated properties just replace/supersede overrides then. Note that you cannot override-edit an existing animation, you’ll have to create a new action.

    You can manually define or remove an override from the context menu of the relevant property.
