The SME Core Interface introduced in 3ds Max 2011 exposes properties and methods related to the Slate Material Editor.

## Interface: SME

Properties:

    sme.activeView : index : Read|Write

Get/set the Slate Material Editor's active View.

Methods:

    <void>sme.Open()

Opens the Slate Material Editor.

    <void>sme.Close()

Closes the Slate Material Editor.

    <bool>sme.IsOpen()

Returns true if the Slate Material Editor is open, false if it is closed.

    <integer>sme.GetNumViews()

Returns the number of Node Views as an integer.

    <index>sme.CreateView <string>name

Creates a new Node View with the given name and returns its index.

    <IObject>sme.GetView <index>index

Returns an IObject:IFP_NodeViewImp object representing the indexed Node View.

    <index>sme.GetViewIndex <IObject>view

Returns the index of the given Node View IObject:IFP_NodeViewImp object.

    <index>sme.GetViewByName <string>name

Returns the index of the named Node View.

    <void>sme.DeleteView <index>index <bool>ask_user

Deletes the indexed Slate Material Editor view.

If the second argument is true, prompts the user for confirmation, otherwise deletes the view without prompting.

    <maxObject>sme.GetMtlInParamEditor()

Returns the material or map current displayed in the Parameter Editor of the Slate Material Editor.

    sme.SetMtlInParamEditor <maxObject>

NEW in 3ds Max 2014: Sets the material or map to be displayed in the Parameter Editor of the Slate Material Editor.

    <Interface>sme.GetNavigator()

Returns an WndBase Interface to the Slate Material Editor's Navigator.

    <Interface>sme.GetMaterialPool()

Returns an WndBase Interface to the Slate Material Editor's Material Pool.

    <Interface>sme.GetParamEditor()

Returns an WndBase Interface to the Slate Material Editor's Parameter Editor.

    <Interface>sme.GetMainframe()

Returns an WndBase Interface to the Slate Material Editor's Main Frame.

    <maxObject>sme.DoMtlBrowseDlg <HWND>parent <DWORD>flags <&boolean>newMat <&boolean>cancel

    newMat is In and Out parameter
    cancel is In and Out parameter

Opens a modal Material/Map browser dialog.

The first argument is the window handle of the parent window, use 0 for none.

The second argument is a flags value controlling the display of materials and maps in the dialog. Possible Flag values are:

1,5,9... - Materials, Sample Slots

2,6,10... - Maps

0,3,7,11... - Maps, Materials, Sample Slots

4,8,12... - None

The third by-reference argument will contain true if a new material was created, false if an existing one was picked.

The fourth by-reference argument will contain true if the Cancel button was clicked, false if the OK button was clicked.

EXAMPLE
    isNew = false
    isCanceled = false
    c = sme.DoMtlBrowseDlg 0 0 &isNew &isCanceled

    <void>sme.OpenMtlBrowseDlg()

Opens the Material Browser Dialog.

### IFP_NodeViewImp : IObject

Interface: NodeView

Properties:

    .name : string : Read|Write

Get/set the name of the Node View.

Methods:

    <integer>GetNumNodes()

Returns the number of nodes in the View.

    <Interface>GetNode <index>index

Returns the Node Interface of the indexed node from the View.

    <Interface>GetNodeByRef <maxObject>ref

Returns the Node Interface to the given Material or Map object reference, or undefined if the reference does not exist in the Node View.

    <Interface>CreateNode <maxObject>ref <&point2>pos

    pos is In and Out parameter

Creates a new node from the given Material or Map object reference at the position specified by-reference.

    <void>DeleteSelection()

Deletes the selected nodes.

    <void>SelectNone()

NEW in 3ds Max 2014: Deselects all nodes in the Node View.

    <void>SelectAll()

NEW in 3ds Max 2014: Selects all nodes in the Node View.

    <void>SelectInvert()

NEW in 3ds Max 2014: Inverts the node selection in the Node View.

    <Interface by value array>GetSelectedNodes()

NEW in 3ds Max 2014: Returns the selected nodes in the Node View as an array of Node Interfaces.

    <void>SetSelectedNodes <maxObject by value array>refs

NEW in 3ds Max 2014: Sets the Node View selection to the array of Materials and/or Maps object references provided as argument.

Setting the selection will deselect any other previously selected nodes.

This function will not open any items in the Parameter Editor - you can use the sme.SetMtlInParamEditor() method documented earlier in this topic.

    <void>ZoomExtents type:<enum>
    type enums: {#all|#selected}
    type default value: #all

NEW in 3ds Max 2014: Zooms the Node View to show all nodes or all selected nodes according to the type optional keyword argument.

Interface: WndBase

Properties:

    .position : point2 by value : Read|Write

Get/set the Position of the Node View.

    .size : point2 by value : Read|Write

Get/set the Size of the Node View.

    .visible : bool : Read|Write

Get/set the Visibility of the Node View.

Methods:

    <void>SetFocus()

Sets the focus on the Node View.

    <Interface>GetParent()

Returns the WndBase interface of the Parent of the Node View.

### Interface: Node

Properties:

    .name : string : Read|Write

Get/set the name of the Node.

    .position : point2 by value : Read|Write

Get/set the Position of the Node inside the Node View.
