# Game Objects Are Not Syncing

## Description

There are multiple reasons why objects may not be syncing with Scene Fusion:

1. Objects with hide flags 'HideInHierarchy' or 'DontSaveInEditor'
2. Objects with components that prevent them from syncing such as sfGuidList or sfIgnore.
3. Objects created by scripts without calling 'Undo.RegisterCreatedObjectUndo'.
4. Objects are children of objects that are not synced because of one of the above.

## Symptoms

Objects are not syncing properly and/or there is no green checkmark beside an object in the hierarchy.

## Solution

1. Make sure the object does not have hide flags 'HideInHierarchy' or 'DontSaveInEditor'.
2. Remove the component that prevents it from syncing. Do not remove the `sfGuidList` from the `Scene Fusion Guids` object. That object is created by Scene Fusion and is not suppose to sync.
3. Call `Undo.RegisterCreatedObjectUndo` after creating objects from scripts, or select the object that is not synced to trigger it to sync.
4. Resolve the issue causing the parent not to sync, or reparent the child so it is no longer a child of an unsynced object.
