modelEditor is undoable, queryable, and editable.

Note that some of the flags of this command may have different settings for normal mode and for interactive/playback mode. For example, a modelEditor can be set to use shaded mode normally, but to use wireframe during playback for greater speed. Some flags also support having defaults set so that new model editors will be created with those settings.

Return value

In query mode, return type is based on queried flag.

Flags

Long name (short name)	Argument types	Properties
exists(ex)	boolean
Returns true|false depending upon whether the specified object exists. Other flags are ignored.
defineTemplate(dt)	string
Puts a command in a mode where any other flags and args are parsed and added to the command template specified in the argument. They will be used as default arguments in any subsequent invocations of the command when templateName is set as the current template.
useTemplate(ut)	string
Force the command to use a command template other than the current one.
panel(pnl)	string
Specifies the panel that the editor belongs to. By default if an editor is created in the create callback of a scripted panel it will belong to that panel. If an editor doesn't belong to a panel it will be deleted when the window that it is in is deleted.
parent(p)	string
Specifies the parent layout for this editor. This flag will only have an effect if the editor is currently un-parented.
unParent(up)	boolean
Specifies that the editor should be removed from its layout. This cannot be used with query.
control(ctl)	boolean
Query only. Returns the top level control for this editor. Usually used for getting a parent to attach popup menus. Caution: It is possible, at times, for an editor to exist without a control. This flag returns "NONE" if no control is present.
mainListConnection(mlc)	string
Specifies the name of a selectionConnection object which the editor will use as its source of content. The editor will only display items contained in the selectionConnection object.
forceMainConnection(fmc)	string
Specifies the name of a selectionConnection object which the editor will use as its source of content. The editor will only display items contained in the selectionConnection object. This is a variant of the -mainListConnection flag in that it will force a change even when the connection is locked. This flag is used to reduce the overhead when using the -unlockMainConnection , -mainListConnection, -lockMainConnection flags in immediate succession.
selectionConnection(slc)	string
Specifies the name of a selectionConnection object which the editor will synchronize with its own selection list. As the user selects things in this editor, they will be selected in the selectionConnection object. If the object undergoes changes, the editor updates to show the change.
highlightConnection(hlc)	string
Specifies the name of a selectionConnection object which the editor will synchronize with its highlight list. Not all editors have a highlight list. For those that do, it is a secondary selection list.
filter(f)	string
Specifies the name of an itemFilter object to be placed on this editor. This filters the information coming onto the main list of the editor.
lockMainConnection(lck)	boolean
Locks the current list of objects within the mainConnection, so that only those objects are displayed within the editor. Further changes to the original mainConnection are ignored.
stateString(sts)	boolean
Query only flag. Returns the MEL command that will edit an editor to match the current editor state. The returned command string uses the string variable $editorName in place of a specific name.
unlockMainConnection(ulk)	boolean
Unlocks the mainConnection, effectively restoring the original mainConnection (if it is still available), and dynamic updates.
updateMainConnection(upd)	boolean
Causes a locked mainConnection to be updated from the orginal mainConnection, but preserves the lock state.
docTag(dtg)	string
Attaches a tag to the Maya editor.
camera(cam)	string
Change or query the name of the camera in model editor.
cameraName(cn)	string
Set the name of the panel's camera transform and shape. The shape name is computed by appending the string "Shape" to the transform name. This flag may not be queried.
displayLights(dl)	string
Sets the lighting for shaded mode. Possible values are "selected", "active", "all", "default", "none".
bufferMode(bm)	string
Sets the graphic buffer mode. Possible values are "single" or "double".
activeOnly(ao)	boolean
Sets whether only active objects should appear shaded in shaded display.
interactive(i)	boolean
Causes this command to modify the interactive refresh settings of the view. In this way it is possible to change the behavior of the model editor during playback for improved performance.
default(d)	boolean
Causes this command to modify the default value of this setting. Newly created model editors will inherit the values. This flag may be used with the -interactive to set default interactive settings.
ignorePanZoom(ipz)	boolean
Sets whether the model panel will ignore the 2D pan/zoom value to give an overview of the scene.
twoSidedLighting(tsl)	boolean
Turns on or off two sided lighting. This may be used with the -default flag.
displayAppearance(da)	string
Sets the display appearance of the model panel. Possible values are "wireframe", "points", "boundingBox", "smoothShaded", "flatShaded". This flag may be used with the -interactive and -default flags. Note that only "wireframe", "points", and "boundingBox" are valid for the interactive mode.
wireframeOnShaded(wos)	boolean
Sets whether the model panel will draw the wireframe on all shaded objects (if true) or only for active objects (if false).
headsUpDisplay(hud)	boolean
Sets whether the model panel will draw any enabled heads up display elements in this window (if true). Currently this requires the HUD elements to be globally enabled.
selectionHiliteDisplay(sel)	boolean
Sets whether the model panel will draw any selection hiliting on the objects in this window.
useDefaultMaterial(udm)	boolean
Sets whether the model panel will draw all the shaded surfaces using the default material as opposed to using the material(s) currently assigned to the surfaces.
useColorIndex(uci)	boolean
Sets whether the model panel will attempt to use color index mode when possible. Color index mode can provide a performance increase for point, bounding box, and wireframe display modes. This may be used with the -default flag.
userNode(un)	string
Allows the user to associate a node name with the modelEditor. The value is automatically updated in the event the node is deleted or renamed.
wireframeBackingStore(wbs)	boolean
Sets whether a backing store is used to optimization the drawing of active objects. This mode can provide a performance increase in wireframe mode for certain scenes.
useRGBImagePlane(ip)	boolean
Sets whether the model panel will be forced into RGB mode when there is an image plane attached to the panel's camera.
imagePlane(imp)	boolean
Turn on/off the display of image plane for the view
updateColorMode(ucm)	boolean
Using this flag tells the model panel to check which color mode it should be in, and to switch accordingly. This flag may be used to update a model panel after a camera image plane has been added or removed.
colorMap(cm)	boolean
Queries the color map style for the model panel. Possible values are "colorIndex" and "rgb".
backfaceCulling(bfc)	boolean
Turns on or off backface culling for the whole view. This setting overrides the culling settings of individual objects. All objects draw in the view will be backface culled. When backface culling is turned on, surfaces becomes invisible in areas where the normal is pointing away from the camera.
xray(xr)	boolean
Turns on or off Xray mode. This may be used with the -default flag.
jointXray(jx)	boolean
Turns on or off Xray mode for joints.
activeComponentsXray(acx)	boolean
Turns on or off Xray mode for active components.
maxConstantTransparency(mct)	float
Sets the maximum constant transparency. Setting this value remaps constant transparency values from the range [0.0, 1.0] to the range [0.0, maxConstantTransparency]. All transparency values are shifted linearly to the new range, so a fully transparency object (transparency 1.0) would appear with a transparency of maxConstantTransparency in the viewport, allowing highly transparent objects to be made visible. This flag only affects constant (non-textured) transparent objects.
displayTextures(dtx)	boolean
Turns on or off display of textures in shaded mode
smoothWireframe(swf)	boolean
Turns on or off smoothing of wireframe lines and points
lineWidth(lw)	float
Set width of lines for display
textureMaxSize(tms)	int
Set maximum texture size for hardware texturing. The integer value must be a power of 2. Recommended values are 128 or 256. If the value specified is larger than the OpenGL maximim textures size for the graphics hardware it will be clamped to the OpenGL size. If many large textures are used in a scene reducing this value improves performance. On Impact texture memory is pinned in RAM so using large textures can cause reliability and performance problems. Again reducing this value will help. Software rendering does not use this value. This flag is obsolete as of Maya 6.5. The maxTextureResolution/mtr argument on the displayPref command should be used instead.
textureMemoryUsed(tmu)	boolean
Returns the total number of bytes used by all texture maps. This is typicly width*height*channels for all texture objects in the scene If the texture is mip mapped all mip map levels are included in the total though not never more than two level will be in use at one time
textureAnisotropic(ta)	boolean
Set whether to perform anisotropic texture filtering. Will work only if the anisotropic texture filtering extension is supported in OpenGL on the graphics system.

Set the type of sampling to be used for texture display. The argument can be either: 1 : means to perform point sample 2 : means to perform bilinear interpolation (default)
textureDisplay(td)	string
Set the type of blending to use for textures. The blend is performed between the destination fragment and the texture fragment. The source is usually the material color. Argument options are: "modulate" : multiply the destination and texture fragment "decal" : overwrite the destination with the texture fragment
textureHilight(th)	boolean
Set whether to show specular hilighting when the display is in shaded textured mode.
fogging(fg)	boolean
Set whether hardware fogging is enabled or not.
fogSource(fsc)	string
Set the type of fog algorithm to use. If the argument is "fragment" (default) then fog is computed per pixel. If the argument is "coordinate" then if the geometry has specified vertex fog coordinates, and the OpenGL extension for vertex fog is supported by the graphics system, then fog is computed per vertex.
fogMode(fmd)	string
This determines the drop-off mode for fog. The possibilities are: "linear" : linear drop-off "exponent" : exponential drop-off "exponent2" : squared exponential drop-off

cameraSetup(cs)	boolean
Based on the model editor name passed in will returns a string list containing camera setups. A camera setup can contain one or more cameras which are associated with each other. Camera setups are defined as pairs of consecutive strings in the list. Each pair is comprised of: a string which identifies an active camera, and a string which defines a script to set up a given active camera. As many pairs of strings can be returned as the number of active cameras. If nothing is returned then it is assumed that no set up is required to activate a given camera.

filteredObjectList(fol)	boolean
For model editors with filtering on (either using an object filter, or isolate select), this flag returns a string list of the objects which are displayed in this editor. Note that this list does not take into account visibility (based on camera frustum or flags), it purely captures the objects which are considered when rendering the view.
modelPanel(mp)	string
Allows the created model editor to be embedded in the named model panel. Intended for use with custom model editors created via the API (i.e. the flag would be used on the derived MPxModelEditorCommand), though the flag may also be used on the base modelEditor command to restore a default Maya model editor to the panel. Note that the model editor previously owned by the panel is deleted.
viewType(vt)	boolean
Returns a string indicating the type of the model editor. For the default model editor, returns the empty string. For custom model editor types created via the API, returns the same string as is returned via the method MPx3dModelView::viewType().

Flag can appear in Create mode of command	Flag can appear in Edit mode of command
Flag can appear in Query mode of command	Flag can have multiple arguments, passed either as a tuple or a list.
