What’s New in the MotionBuilder 2013 SDK?

• Programming Environment and Code Refactoring Changes
• MotionBuilder and its distributed plug-ins are now compiled using Visual Studio 2010 (Service Pack 1).
• FBContainer has been renamed to FBVisualContainer for uniformity of cross-product naming schemes.
• const correctness improvements.
• Although not enforced in this release, we recommend that the "H" prefix in classes such as HFBPlug be removed and replaced by the pointer suffix "*", for example: FBPlug*. This change is intended to facilitate the use of the documentation system in the near future.
• FBShader has been heavily refactored for performance.
• New Classes
• FBSyncReference - Will allow the MotionBuilder application to sync its time with a device's time. For more information, consult the ordevicesync_device plugin.
• FBTimeCode - A timecode contains the time and frame information used to identify a specific moment in a timeline, often used in video and audio production. This class can help in the conversion of a point in time from one framerate domain to another.
• FBHUD, FBHUDElement - These classes represent the new Heads-Up Display (HUD) feature in MotionBuilder. A HUD will be connected to a camera, and appears as a 2D overlay. This overlay can be used to display information about the take: the current time and frame number
• FBFileMonitoringManager - This class can be used to help monitor operating system file events. By contrast, the event properties in FBApplication will only monitor events triggered within the MotionBuilder application.
• FBNamespace - This class has been exposed to help facilitate the use of namespaces among scene elements. Functions: FBFindModelByLabelName(), FBFbxOptions::NamespaceList, FBFbxOptions::SetNamespaceList(), FBFbxOptions::GetNamespaceList(), and the FBScene's namespace related functions (FBScene::NamespaceImport()) can filter, select, import and export scene elements using namespaces.
• New Methods and Added Functionality
• FBAnimationNode::KeyCandidate(), FBPropertyAnimatable::KeyAt() - These functions  provide the ability to key at a given time without moving time.
• FBSystem.ConfigPath, FBSystem.UserConfigPath, FBSystem.TempPath - These properties respectively will define MotionBuilder software’s directory paths for config files, user config files, and temporary files.
• FBAudioClip - A substantial amount of functionality has been added to this class. Consult the header files and class documentation for more information.
• FBMenuManager - Functionality has been added to this class to help manipulate and remove MotionBuilder software’s UI top menu bar.
• FBComponent::GetFullName() - Retrieves an object's unique name.
• FBStory, FBStoryFolder, FBStoryTrack - Added the capability to record stories on disk with properties: FBStory::RecordToDisk and FBStoryFolder::RecordClipPath.
• FBDevice::ModelBindingCreate, FBDevice::ModelBindingRootsList - These functions allow you to create a model binding from a device, or obtain a list of possible root models which can be bound to the device.
• FBModel - Exposed additional properties to facilitate custom rendering. Viewport dimensions can be set in the model, which will only be updated and valid during custom renderer callbacks (FBModel::CameraViewportX, FBModel::CameraViewportY, FBModel::CameraViewportWidth, FBModel::CameraViewportHeight). Motion blur properties have also been added: FBModel::MotionBlurIntensity, FBModel::UseMotionBlur, FBModel::UseRealTimeMotionBlur.
• FBModelNull, FBModelMarker - Overloaded several FBModel base class functions in these subclasses to help increase user customization. These functions are: FBModelMarker/FBModelNull::FbxStore(), FBModelMarker/FBModelNull::FbxRetrieve(), FBModelMarker/FBModelNull::FbxGetObject(), and FBModelMarker/FBModelNull::FbxGetObjectSubType().
• FBMaterial - Custom material support, and added sample project (OpenRealitySDK/Samples/miscellaneous/material_template)
• FBRenderer - Added new functionality: FBRenderer::GetViewingCamera() to obtain the current camera, FBRenderer::InPicking() to determine if the renderer will be in the picking phase, and a variety of certain other functions and properties related to picking.
• FBAudioRenderOptions() - This class has been added to help specify audio rendering options, which can be passed as a parameter to FBApplication::AudioRender(). Consult the Scripts/Samples/Audio/AudioRendering.py sample for more details.
• FBEvaluateManager - Added functionality will allow for computationally intensive tasks to be registered and run as callbacks in a background thread (FBEvaluateManager::RegisterEvaluationGlobalFunction(), FBEvaluateManager::UnregisterEvaluationGlobalFunction())
• Misc and Optimizations
• Optimized functions FBFindObjectByFullName() and FBDeleteObjectsByNames().
• Optimized the merging of multiple files transaction workflow: FBMergeTransactionBegin(), FBMergeTransactionEnd().
