Layer Editor

By default, the Layer Editor is displayed at the bottom of the Channel Box panel. Click the Channel Box/Layer Editor icon to open it.

The Layer Editor contains tabs that let you display two different editors for working with different types of layers.

In all cases, there is a default layer where objects are initially place upon creation.

You can display the Layer Editor independently if you turn off the Show Layer Editor within Channel Box option in the Preferences window (choose Windows > Settings/Preferences > Preferences, then select UI Elements).

Then click the Layer Editor icon in the Status line to open it.
Note: The Render Layer Editor that was available in the Layer Editor in previous versions has been replaced by the new Render Setup system. If you want to use the legacy Render Layer system, open the Preferences window, select the Rendering category, and then select Legacy Render Layers as the Preferred Render Setup system.
