4. Synchornization

Synchronization behavior and interval#

When Auto Sync is enabled Synchronization daemon runsin background ensuring that model is synced based on the direction settings

Sync interval is 1s by default. It can be edited under Linker's add-on preferences.

Synchronization Direction#

| Direction | Automatic and one-shot Sync behavior |

| --- | --- |

| Two-way | Imports disk changes and exports Blender changes. If both sides changed, the newer timestamp wins. |

| Import only | Updates Blender from disk and never exports automatically. |

| Export only | Updates the external file from Blender and never imports automatically. |

When selected linked models share a direction, choosing another direction applies it

to all of them. With mixed directions, the buttons are disabled and the panel shows

Multiple values. Select one policy group at a time to resolve the difference.

Batch Sync Support#

• Sync (N) applies each selected model's configured direction once.

• Save (N) immediately exports every selected linked model, including Import-only

models.

• Reload (N) immediately imports every selected linked file, including Export-only

models, and replaces its current model members.

• Sync All processes every valid linked model in the current scene and respects

each model's direction. A failure in one model does not stop the rest.

• Auto Sync periodically applies the direction policy. Configure its interval in

Linker's add-on preferences.

N is the number of distinct linked models represented by the selection.

These operations act once on every distinct linked model represented by the selection:

• Sync, Save, Reload, Make Relative, and Unlink

• direction changes, when current directions match

• format-setting changes, when current values and formats match

• preset loading, when current preset selections match
