Dear All,

Where can I find MEL commands for render layers? I need MEL commands for render layers 'blend mode' and options of 'Render All Layers'.

Thank you

-exists(-ex)


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. -parent(-p) string

The parent layout for this control. -enable(-en) boolean

The enable state of the control. By default, this flag is set to true and the control is enabled. Specify false and the control will appear dimmed or greyed-out indicating it is disabled. -width(-w) int

The width of the control. The control will attempt to be this size if it is not overruled by parent layout conditions. -height(-h) int

The height of the control. The control will attempt to be this size if it is not overruled by parent layout conditions. -visible(-vis) boolean

The visible state of the control. A control is created visible by default. Note that a control's actual appearance is also dependent on the visible state of its parent layout(s). -isObscured(-io)


Return whether the control can actually be seen by the user. The control will be obscured if its state is invisible, if it is blocked (entirely or partially) by some other control, if it or a parent layout is unmanaged, or if the control's window is invisible or iconified. -manage(-m) boolean

Manage state of the control. An unmanaged control is not visible, nor does it take up any screen real estate. All controls are created managed by default. -numberOfPopupMenus(-npm)


Return the number of popup menus attached to this control. -popupMenuArray(-pma)


Return the names of all the popup menus attached to this control. -preventOverride(-po) boolean

If true, this flag disallows overriding the control's attribute via the control's right mouse button menu. -annotation(-ann) string

Annotate the control with an extra string value. -backgroundColor(-bgc) float float float

The background color of the control. The arguments correspond to the red, green, and blue color components. Each component ranges in value from 0.0 to 1.0. (Windows only flag) -docTag(-dtg) string

Add a documentation flag to the control. The documentation flag has a directory structure like hierarchy. Eg. -dt render/multiLister/createNode/material -dragCallback(-dgc) script

Adds a callback that is called when the middle mouse button is pressed. The MEL version of the callback is of the form: global proc string[] callbackName(string $dragControl, int $x, int $y, int $mods)

The proc returns a string array that is transferred to the drop site. By convention the first string in the array describes the user settable message type. Controls that are application defined drag sources may ignore the callback. $mods allows testing for the key modifiers CTL and SHIFT. Possible values are 0 == No modifiers, 1 == SHIFT, 2 == CTL, 3 == CTL + SHIFT.

In Python, it is similar, but there are two ways to specify the callback. The recommended way is to pass a Python function object as the argument. In that case, the Python callback should have the form:

def callbackName( dragControl, x, y, modifiers ):

The values of these arguments are the same as those for the MEL version above.

The other way to specify the callback in Python is to specify a string to be executed. In that case, the string will have the values substituted into it via the standard Python format operator. The format values are passed in a dictionary with the keys "dragControl", "x", "y", "modifiers". The "dragControl" value is a string and the other values are integers (eg the callback string could be "print '%(dragControl)s %(x)d %(y)d %(modifiers)d'")

-dropCallback(-dpc) script

Adds a callback that is called when a drag and drop operation is released above the drop site. The MEL version of the callback is of the form: global proc callbackName(string $dragControl, string $dropControl, string $msgs[], int $x, int $y, int $type)

The proc receives a string array that is transferred from the drag source. The first string in the msgs array describes the user defined message type. Controls that are application defined drop sites may ignore the callback. $type can have values of 1 == Move, 2 == Copy, 3 == Link.

In Python, it is similar, but there are two ways to specify the callback. The recommended way is to pass a Python function object as the argument. In that case, the Python callback should have the form:

def pythonDropTest( dragControl, dropControl, messages, x, y, dragType ):

The values of these arguments are the same as those for the MEL version above.

The other way to specify the callback in Python is to specify a string to be executed. In that case, the string will have the values substituted into it via the standard Python format operator. The format values are passed in a dictionary with the keys "dragControl", "dropControl", "messages", "x", "y", "type". The "dragControl" value is a string and the other values are integers (eg the callback string could be "print '%(dragControl)s %(dropControl)s %(messages)r %(x)d %(y)d %(type)d'")

-label(-l) string file:///Applications/Autodesk/maya2009/docs/Maya2009/en_US/gfx/create.giffile:///Applications/Autodesk/maya2009/docs/Maya2009/en_US/gfx/query.giffile:///Applications/Autodesk/maya2009/docs/Maya2009/en_US/gfx/edit.gif
Label text for the button. -color(-cl) float float float file:///Applications/Autodesk/maya2009/docs/Maya2009/en_US/gfx/create.giffile:///Applications/Autodesk/maya2009/docs/Maya2009/en_US/gfx/edit.gif
Layer color, specified with normalized real numbers in R, G, B space. -transparent(-t) boolean

Indicate whether the render layer color is visible or transparent. -name(-n) string

Name of the layer. -identification(-id) int

This is the integer identification number associated with the render layer. -command(-c) string

Set the command to call on a single click. -doubleClickCommand(-dcc) string

Set the command to call on a double click. -renameCommand(-rc) string

Set the command to call when the render layer gets renamed. The string '#1' will be substituted with the control's name and '#2' will be replaced with the layer's new name. -current(-cr) boolean

Set this button to display as the current render layer. The current render layer is the one which the user has the option of adding all newly created objects into. NB: Setting the render layer button to this state has no effect on the actual current render layer. -select(-s) boolean

Set this button to display as a selected render layer. -labelWidth(-lw)


Query the width of the label part so as to determine if button clicks are in the label part or the colour swatch part. -renderableCommand(-rdc) string

Command that is called when the renderable indicator of the render layer button is pressed. -isRenderable(-ir)


True if the button has a renderable state -materialOverrideCommand(-moc) string

Command that is called when the material override indicator of the render layer button is pressed. -hasMaterialOverride(-hmo)


True if the button has material override turned on -renderFlagOverrideCommand(-foc) string

Command that is called when the render flag override indicator of the render layer button is pressed. -hasRenderFlagOverride(-hfo)


True if the button has render flags override turned on -renderSettingsOverrideCommand(-soc) string

Command that is called when the render settings override indicator of the render layer button is pressed. -hasRenderSettingsOverride(-hso)


True if the button has render settings override turned on -recycleCommand(-rcc) string

Command that is called when the recycle indicator of the render layer button is pressed. -isRecycle(-irc)


True if the button has a recycle state -handleNodeDropCallback(-hnd) string

Command that is called when a node is dropped on the render layer button.

Thank you for your reply, Kristaan
I want the commands for the Render layers blend mode. And also commands for Render All Layers > Render All Layers options.
