Entities Preferences reference

The Preferences window in the Unity Editor (Unity > Settings) contains some specific Entities settings, as follows:

Hierarchy window

Property	Description
Update Mode	Set how to update the Entities Hierarchy window: Synchronous: Updates the hierarchy in a blocking manner. Data is always up to date, but might impact performance. Asynchronous: Updates the hierarchy in a non-blocking manner, over multiple frames if needed. Data might be stale for a few frames, but the impact on performance is minimized.
Minimum Milliseconds Between Hierarchy Update Cycle	Set the minimum amount of time to wait between hierarchy update cycles in milliseconds. Increase this value to update the Entities Hierarchy window less frequently, which has a lower impact on performance.
Exclude Unnamed Nodes For Search	Excludes unnamed entities in the results of searching by string in the Entities Hierarchy window. If there are a lot of unnamed entities, this can speed up searching.
Advanced Search	Enables advanced query syntax in the Entities Hierarchy window search field, including component filters (all/none/any), shared component filters, entity index tokens, EntityQueryOptions, and autocomplete. Default: on.
Show Hidden Entities	Displays entities in the Hierarchy window that are hidden by default, such as internal system entities. Default: off.
Type of Worlds Shown	Controls which world types are visible in the Hierarchy window. Default: Live.

Systems window

Property	Description
Show 0s in Entity Count And Time Column	Displays 0 in the Entity Count column when a system doesn't match any entities. If you disable this property, Unity displays nothing in the Entity Count column when a system doesn't match any entities.
Show More Precision For Running Time	Increases the precision from 2 to 4 decimal places for the system running times in the Time (ms) column.

Baking

Property	Description
Scene View Mode	Select what the Scene view displays for entities inside open subscenes: Authoring Data: The Scene view displays the authoring GameObjects, rendered using the render pipeline configured in the project. Baked entities are only visible in the Game view. Runtime Data: The Scene view displays the baked entities, rendered using the Entities Graphics system. Authoring GameObjects are hidden.
Live Baking Logging	Enable this property to output a log of live baking triggers. This can help diagnose what causes baking to happen.
Clear Entity cache	Forces Unity to re-bake all subscenes the next time they're loaded in the Editor, or when making a Player build.

Journaling (deprecated)

Warning

The Journaling window is deprecated and will be removed in a future release.

Property	Description
Enabled	Enable Journaling data recording.
Total Memory MB	Set the amount of memory in megabytes allocated to store Journaling record data. Once full, new records overwrite older records.
Post Process	Post-process journaling data in the Journaling window. This includes operations such as converting GetComponentDataRW to SetComponentData when possible.

Advanced

Property	Description
Show Advanced Worlds	Displays advanced worlds in the different world dropdowns. Advanced worlds are specialized worlds like the Staging world or the Streaming world which serve as support to the main worlds.
