## Controllers

Expression Controllers

Float_Expression : FloatController

Point3_Expression : Point3Controller

Position_Expression : PositionController

Scale_Expression : ScaleController

The new implementations of the Expression controllers provide complete MAXScript access through the new IExprCtrl interface. All expression controllers listed above expose that interface.

Script Controllers

Using Script Controllers

Script controllers are now based on the same code as the new scriptable Expression controllers, providing additional features like access to time constants, the ability to define user variables and assign constants, controllers, tracks and nodes to them, a debug window showing dynamically all user variables and the controller value as the time changes, a description field and more.

## Cameras

Camera Common Properties, Operators, and Methods

New properties have been added to cameras to provide access to the FOV type flyout and the current FOV value dependent on that flyout.

CameraFOV Structure

New structure has been added. It provides methods to convert FOV into MM and back and Current FOV Type to horizontal FOV and back.

## Materials and Texture Maps

Architectural : Material

New MAXScript properties have been added to the Architectural material to allow inverted processing of Reflections, Refractions and Self-Illumination by Exposure Controls and to exclude the material from Exposure processing. These properties are not exposed in the User Interface!

UVGenClass : Material

New properties have been added to the StandardUVGen (accessed via the .coordinates property of texture maps) to expose the real-world scale properties of all texture maps using the StandardUVGen class, incl.Bitmaptexture, Bricks (Tiles), Checker, Combustion, Gradient, Gradient_Rampand Swirl maps.

## Bitmap IO

OpenEXR : BitmapIO

NewBitmap IO provides support for the OpenEXR file format.

TIF: BitmapIO

New#color16 type added to the getType() and setType() enums.

## Renderer

Controlling the Renderer

New optional keyword arguments added to the render() command to control the rendering of Multipass camera effects and Render Elements when calling the renderer from MAXScript.

## Render Elements

Material_ID : RenderElement

New RenderElement allows the output of Material IDs.

Object_ID : RenderElement

New RenderElement allows the output of Object IDs.

ZRenderElement - superclass: MAXObject

New Update Property added to the RenderElement.

## Bake Elements

Ambient_Occlusion : BakeElement

New Bake Element allows the Ambient Occlusion to be rendered to texture.

## Radiosity

Radiosity : RadiosityEffect

New properties have been added to the Radiosity RadiosityEffect to provide controls over the new Adaptive Subdivision feature.

The documentation has been reordered to reflect the location of the respective controls in the user interface for easier navigation.

## mental ray

mental_ray_renderer : RendererClass

New properties have been added to the mental_ray_renderer RenderClass to provide access to the Final Gather bounces count, the RapidShading samples count, the displacement Smoothing option, the Material Override option, the Motion Blur Shutter offset and the Frame Buffer type.

Interface: ATSCustomDepsOps

A new Core Interface has been added to provide access to the Custom Dependencies dialog of the Asset Tracking System.

Interface: LoadSaveAnimation

A new Core Interface has been added to provide access to the new Animation Loading and Saving feature.

Interface: sceneStateMgr

A new Core Interface has been added to provide access to the new Scene State manager feature. Scene State allows you to capture the current settings of the scene and restore them later.

Interface: batchRenderMgr

A new Core Interface has been added to provide access to the new Batch Render manager feature. It will let you specify multiple cameras with various settings, optional scene states and render presets and render with a single click of a button locally or on the network.

Interface: heightManager

A new Core Interface has been added to VIZ 2006. The Interface does nothing in 3ds Max 8 since the actual functionality is implemented by Light-creating MacroScripts shipping with VIZ 2006. The interface is only used to manage values used by these MacroScripts to create Lights at pre-defined custom Z heights.

Interface: globalDXDisplayManager

A new property has been added to the existing interface to enable and disable DirectX Scene Effects.

Interface: gridPrefs

The gridPrefs interface originally introduced in Gmax has been added to 3ds Max 8 and enhanced with more properties. It can be used to access and change the Home Grid Preferences.

Interface: BrushPresetMgr

This new interface exposes the Brush Preset Manager to MAXScript.

Interface: SkinUtils

A new method for importing skin data without opening a dialog added to the existing interface.

BipWorkBench Core Interface

New methods added to the existing interface to control the Quaternion curvers display.

Interface: trackviews

New .exists() method added to the existing interface and returns true if the specified trackview exists and false if it does not. It can be used to prevent Runtime errors from the .isOpen() method in the same interface.

## XRefs

Interface: objXRefMgr

A new core interface has been added to provide access to the Object XRef's source and proxy file names and item names.

XRef_Material : Material

A new class whose instances are used to XRef materials from external files.

XRefAtmosWrapper

A new non-creatable class whose instances are used to XRef atmospheric effects from external files.

XRefObject : Node

New property added to the existing XRefObject node class to expose the actual object used by the XRef.

Interface: objXRefs

New method added to the existing objXRef interface to return the number of empty XRefs.

## Cloth Extension

MAXScript Extensions for Cloth

New modifiers have been added to 3ds Max to simulate Cloth - Cloth : Modifier andGarment_Maker : Modifier

## Hair & Fur Extension

MAXScript Extensions for Hair & Fur

New classes have been added to 3ds Max to generate and render Hair and other advanced surface-distributed effects like grass, trees etc. -HairMod : Modifier

## Miscellaneous

maxops.overrideControllerRangeDefault

New option to control the infinite/limited range of procedural controllers.

Interface: maxOps

New methods to get and set the default tangent types of new keys added to the maxOps interface.

New method to get consistent color values from integer IDs added to the maxOps interface.

BitMethods

New bit methods added to the existing bit structure to convert integers to floats, floats to integers, swap bytes and check whether a value is NaN or a finite number (not a NaN).

timeConfiguration.playbackLoop

New system global to control the state of the Loop checkbox in the Time Configuration dialog.
