Opens via View › Layer Manager.
Organizes mission objects into named layers. Layers are an editor-only concept and have no effect on mission gameplay. They exist purely to help manage visibility in the viewport while editing.
Lists all layers in the mission. Each layer has a checkbox; uncheck it to hide all objects on that layer in the viewport, check it to show them again. Newly placed objects are automatically assigned to the Default layer.
Use Add Layer to create a new layer. Use Rename Layer to rename the selected layer; every object on it is updated to the new name. Use Delete Layer to remove the selected layer, reassigning its objects to the Default layer. The Default layer cannot be renamed or deleted.
Works in conjunction with layers to provide additional visibility control. Allows hiding objects by type or by IFF team regardless of which layer they are on.
