This editor lets you organize objects in your scene so you can show, hide, or edit them all at once.
In the default Maya Creative layout, you can switch between the Display Layer editor and the Animation Layer Editor by clicking the tabs.
The V P and T boxes that appear beside each layer name are view settings you can switch on and off.
A “T” means the objects in the layer are templated: they are displayed in wireframe and can't be selected. An “R” means that the objects the layer is referenced: they can't be selected, but keep the current display mode. A blank box means the objects in the layer are normal and can be selected.
Creates a new display layer, depending on the selection in the drop-down list, with a default name, for example layer1.
Selects the objects contained in the selected layer(s).
Removes all objects from the selected layer(s) and assigns them to the default layer. The selected layer(s) becomes empty so you can assign other objects.
Opens the Relationship Editor for removing or adding objects to layers.
Opens the Attribute Editor for the selected layer(s). There are some attributes in the Attribute Editor not available through the Edit Layer window.
Deletes the selected layer(s), but not the objects in the layer.
Delete layers if they have no content.
You can set all layers or selected layer characteristics. When you set selected layer characteristics, you can specify whether unselected layers will be affected or not.
The above layer settings menu items are also available when you right-click a Display layer.
Sorts layers by name.
Sorts layers by time of creation.
You can set the following binary options:
When using namespaces, object names can sometimes get very long. This can make it difficult to differentiate objects by name. Turning off the display of namespaces replaces the namespace portion of a node’s name (if any) with “...:”. The shortened name makes it easier to distinguish between different objects in your scene.
Namespaces are the preferred method for managing naming when working with file references in Maya. It is not recommended that you employ Maya's renaming prefix convention when using file referencing. While the DAG path or long name of a node may make it unique when using renaming prefixes, they do not work consistently within file referencing and complicate the hierarchical DAG changes, which may cause problems later on.
The following commands are available when you right-click a layer:
Add or remove objects from a display layer. You can also select all objects in the current display layer.
See above.
Removes all objects from a layer, leaving it empty.
Deletes the layer.
Deletes all selected layers.
See above.
Type the name of the layer.
Turn this option off to disable the effects of the layer. Objects in the layer appear and behave as though they do not belong to the layer.
Select how the layer appears.
Objects in the layer display normally, according to the settings for the layer. You can select objects in the layer and snap to them.
Objects in the layer become templates. You can see template objects in the workspace, but you cannot select them, nor can you snap them.
You can snap to objects in the layer, but you cannot select them or modify them.
Select the level of display detail for layer objects:
Displays full detail for layer objects.
Shows objects as boxes that represent their bounding volumes. Bounding boxes speed up Maya operations making a significant difference for complex models.
Turn on to make layer objects appear shaded when in shaded display.
Turn on to show textures on layer objects when in shaded display.
Turn on to make the objects in the layer visible.
Select the color of all objects belonging to the layer.
This is the number assigned to the layer.
To facilitate the merging of layers when you read in files, select Windows > Settings/Preferences > Preferences, click the Files/Projects category, and in the Display Layer section select one of the following options for File Import Merge:
All layers read in are put in a new layer, and renumbered and renamed, if necessary to preserve uniqueness.
All layers read in that have the same index number as an existing layer are merged with that layer rather than creating a new layer.
All layers read in that have the same name as an existing layer are merged with that layer rather than creating a new layer.
You can associate each display layer with a different color so that it is easier to identify which objects are in each display layer in the Hypergraph and in the scene view.
If the object or node is selected, it still appears in yellow in the Hypergraph and outlined in green in the scene view. You only see the color for each display layer if the object and node is not selected.
To associate each display layer with a color
All objects in the selected layer appear in the designated color in the scene view and all nodes in the selected layer appear in the designated color in the Hypergraph.
In this image, layer 1 is associated with pink and layer 2 is associated with purple.
