库覆盖

    Note

    It is considered as experimental, and the 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:

    • Adding new modifiers and constraints, anywhere in the stack.

    • 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 data-block menu in the UI (Shift-LMB on the chain icon to the right), in which case only that specific usage will be remapped to the new local override.

    This one operates in the 3D Viewport, 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 submenu 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

    For this operator to work properly, it is crucial that all the collections needed by the character are children of the root (linked and instantiated) one. Otherwise, some won’t be automatically overridden, and manual work will be needed to fix the override.

    Object ‣ Relations ‣ Convert Proxy to Library Override

    Converts older a to a local override. This operator is used to help convert older blend-files to the new override system. In the future, this conversion will likely happen automatically.

    Essentially, an 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 overrides.

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

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