A mapbutton item is used to place a button in the rollout that will display the 3ds Max Material/Map Browser dialog when clicked. Only texture maps will be displayed in the Material/Map Browser dialog.

The syntax is:

mapbutton <name> [ <caption> ] [map:<texturemap>] [images:<image_spec_array>] [toolTip:<string>]

The default alignment of mapbutton items is #center.


rollout test_mapbutton "Background"


label sbm_lbl "Background Map:"

mapbutton choosemap "<<none>>" tooltip:"Select Background Map" width:120

on choosemap picked texmap do


environmentmap = texmap

choosemap.text=classof texmap as string



createDialog test_mapbutton





The initial textureMap value returned by the map property before the user has selected a texture map using the mapbutton. Defaults to undefined.


An image-specification array for providing bitmap images for the mapbutton. If this is specified, the <label> is ignored and the contents of the mapbutton are replaced with the bitmaps.

The form is:

images:#(<image>, <maskImage>, <count_integer>, <enabled_out_image_index>, <enabled_in_image_index>, <disabled_out_image_index>, <disabled_in_image_index>)

where <image> and <maskImage> can be either a bitmap file-name string or a MAXScript bitmap value. <count_integer> specifies the number of sub-images in the bitmaps, and the image_index values specify which sub-image in the bitmaps is to be used for each of the four mapbutton states.

For example:

bm1 = render camera:$cam01 outputSize:[80,60]


mapbutton foo images:#(bm1, undefined, 1, 1, 1, 1, 1)

would use a rendering as the mapbutton image, and

mapbutton decay images:#("dcybtns.bmp", "dcymask.bmp", 6, 1, 4, 1, 4)

would use sub-images 1 and 4 of bitmaps dcybtns.bmp and dcymask.bmp for the out and in states of the mapbutton, respectively.

See also Image Buttons.


Provides text for a tooltip for the mapbutton. No tooltip if unsupplied.


<mapbutton>.map TextureMap

The current textureMap value for the mapbutton, or the textureMap value specified by the map parameter if the user has not yet selected a texture map.

<mapbutton>.images Array

Sets the image-specification array for the mapbutton. This property is write-only.

For example:

-- re-render, update button

bm1 = render()

foo.images = #(bm1, undefined, 1, 1, 1, 1, 1)

<mapbutton>.tooltip String

new.gif NEW in 3ds Max 9: Get/set the tooltip string of the checkbutton.

For example:

rollout test "Test"


mapbutton map_test "Map Button" tooltip:"This is a map button"


createDialog test

test.map_test.tooltip = "The tooltip has changed!"


on <mapbutton> picked <arg> do <expr>

Called when the user selects a texture map from the Material/Map Browser dialog while in the mapbutton pick command mode. The <arg> argument will contain the selected textureMap value. The handler is not called if the user cancels out of the Material/Map Browser dialog.

on <mapbutton> rightclick do <expr>

Called when the right mouse button is released over the button. Available in 3ds Max 8 and higher.



When a mapButton is used in a rollout in a scripted material or textureMap plug-in, and so turn up the Material Editor, it behaves with the same functionality as sub-map buttons do in other materials and maps. This includes supporting drag-and-drop with instance/copy, and opening sub-maps if they have been assigned.
