The following section describes limitations, workarounds (where applicable) about this release.
Bug Number Description
MAYA-21556 Grease Pencil : Does not work when camera is parented to an animated object.

Workaround : Use a parent constraint to constrain the camera to the animated object.
MAYA-21948 Grease Pencil : Scaling frames on the time slider does not respect "snapping" time slider preferences.
MAYA-22330 Live Connection sometimes fail between Maya and Motion Builder.

Workaround : After MotionBuilder starts and shows “Connected to Maya”, there is a small “Update” button beside the “Connected to Maya” status. Click on “Update” and then retry ”Live Connection” from Maya. 
MAYA-22784 Mirror Skin Weights on selected components produces incorrect results.
MAYA-11720 Update Maya Library to run as a process

Previously, in FaceRobot, each library referring to files (Stage 1 (Assemble): Heads, Parts, Actor, Custom and Type; Stage 5 (Act): Motion and Pose) only supported one path at a time. This has been modified to support many paths by storing the previous paths in a drop down menu. Selecting a new library path now stores it in the drop down menu for easy access later on when jumping from one library path to another.
MAYA-18039 MUiMessage::MStringFunction has been removed as it was a duplicate of MMessage::MStringFunction. Any plug-ins using the former must be changed to use the latter instead.
MAYA-16207 Support down casting for user created classes

Currently Maya supports the type cast inside the inheritance hierarchy of MPx based objects; each of such class has a static member function named CastFromIntPtr.
MAYA-16212 There are no mechanics to release resources

All the MPx based objects in C# are referenced by their C++ MPx object counterpart. These objects will be disposed by the garbage collection mechanism as common C# objects.
MAYA-17133 Locked DAG container allows parenting

Old behavior: If a dagContainer (itself) is locked, the user can still parent another unlocked dag node under this dagContainer.

New behavior: If a dagContainer (itself) is locked, the user can NOT parent another unlocked dag node under this dagContainer.

For any other dag node that is not a dagContainer, parenting any other unlocked dag node under it is still permitted.
MAYA-22303 When parenting an object into a Scene Assembly containing an asset, the object is parented, but disappears in the (Outliner) hierarchy.
MAYA-6185  Bullet acceleration has no effect on Rigid Bodies.
Cache Representation - Baked Geometry  
MAYA-22558 The gpuCache plug-in in the devkit does not compile.

Workaround: Define WIN32_LEAN_AND_MEAN macro in Visual Studio project settings.
MAYA-22579 GPU memory of Quadro 4000 on Mac is detected as -2048 by gpuCache, and then the Maximum VRAM for gpuCache is set as 0 by default.

You must manually set the "Maximum VRAM for All Cache Buffers". Do not use the default setting; otherwise the playback performance of the gpuCache will not be optimal because it doesn't use GPU memory at all.
MAYA-22607 DirectConnect not supported on Mac OS X 10.6.8

Workaround: Upgrade to Mac OS X Mountain Lion (10.7), or higher.
MatchMover documentation not updated

Workaround: Find updated documentation for MatchMover online:
Composite documentation not updated

Workaround: Find updated documentation for Composite online:
MAYA-3088 The mayaBinary file size limitation (2 GBytes) has been removed to support a larger file size.

Maya now writes Maya binary files with a new IFF format. The chunk size is 64-bit. The new format is not compatible with the old IFF format where the chunk size is 32-bit. Older releases of Maya cannot open these new new binary files.
MAYA-18148 File > Open: reference fails with an 'unknown file type' error if the plug-in describing the file type is not loaded.

Workaround: A user can force a plug-in to autoload by modifying the pluginPrefs.mel file.


When using the Autodesk uninstall tool with the Maya package, if you choose to uninstall a program other than Maya, a warning appears and you are unable to uninstall. The same occurs for Composite and MatchMover.
Workaround: Use Add/Remove programs instead.

Plug-in assembly load error occurs when using the 'send to' options from the Ultimate Suite

The 'send to' options from the Ultimate Suite throws an error on Windows 8 when using Maya to Max/Mudbox to Max


1.    Start Max first before selecting “Send to 3ds Max”.

2.    Do not call the Windows function SetDllDirectory() during Maya's startup.

Setting the environment variable MAYA_PRIVATE_DLL_PATH to a value that is really long; that is, one that is greater than the Windows MAXPATH (512 characters), forces the effective path to be NULL. The call to SetDllDirectory will not be made. This needs to be set before Maya is run, and cannot be added to the Maya.env file for it to be recognized. (Set the environment variable instead using other methods such as: from the command window before launching Maya, via launching Maya from a batch file, or from My Computer > Properties > Advanced system settings > Environment Variables.)

MAYA-1436 Localized default file name causes crash when one-click function is used to send file to other software.
MAYA-18046 "Ctrl+Space" conflicts with the default hotkey used for changing input method.

Workaround: If you are running Maya in a Simplified Chinese environment, switch between the standard view and full-screen view of the current panels by using the Ctrl + Shift + Spacebar hotkey.


There are some broken Help links under toolclips and context help

If you run Maya with a Japanese or Chinese interface and then access the context sensitive help, and your Help Location is set to "Autodesk Web Site" (the default option) under Windows > Settings/Preferences > Preferences > Interface > Help , Maya automatically directs you to the localized version of the Maya help on

If you access the context sensitive help or links from toolclips before the localized version of the Maya help is available, you will obtain a 'page not found' error.

To work around this issue, you can reset your link to the Maya 2013 version of the localized Maya help.

To do so, select Windows > Settings/Preferences > Preferences > Interface > Help > Help Location > Custom and set the following as your custom path:

For Simplified Chinese:

For Japanese:

When the localized versions of the Maya 2014 online help become available, you can reset this preference to "Autodesk Web Site".

However, this workaround is only applicable to UI that existed in Maya 2013 or below. For UI that is new or updated, you can either refer to the English version of the Maya 2014 help on or wait until the localized version of the Maya 2014 help is available.


Cannot change File Textures "Attribute to paint" list for 3D Paint Tool in Simplified Chinese and Japanese UI mode


If you are using a Japanese or Simplified Chinese version of Maya, and you right-click the object and select Paint > 3D Paint, you will not be able to use the 'Attribute to paint' drop-down list under the File Textures section of the 3D Paint tool settings.


To workaround this problem, remove the following resource file:

Windows 64-Bit

Japanese: C:\Program Files\Autodesk\Maya2014\resources\l10n\ja_JP\scripts\

Simplified Chinese: C:\Program Files\Autodesk\Maya2014\resources\l10n\zh_CN\scripts\


Mac OS

Japanese: /Applications/Autodesk/maya2014/

Simplified Chinese: /Applications/Autodesk/maya2014/

MAYA-22637 HIK Control loads plug-in language resource file many times in Japanese mode

When using Maya in Japanese or Simplified Chinese, if you try to use the Character Controls and click the Control tab, Maya attempts to load a plug-in language resource file multiple times and Maya slows down as a result.


1. Comment out loadPluginLanguageResources in mayaHIKInitStrings.mel

By default, the file is installed in following path;
Windows: c:\Program Files\Autodesk\Maya2014\scripts\others\mayaHIKInitStrings.mel
MacOSX: /Applications/Autodesk/maya2014/

Comment out line 32 as below:
loadPluginLanguageResources( "mayaHIK", "mayaHIK.pres.mel");
// loadPluginLanguageResources( "mayaHIK", "mayaHIK.pres.mel");

2. Run the following command manually in the Script Editor before using HIK to initialize the HIK plug-in resource for Japanese and Simplified Chinese UI:

loadPluginLanguageResources( "mayaHIK", "mayaHIK.pres.mel");

Most of the HIK UI appears localized, except for the effector context menu that appears in English.

An alternative workaround is to use Maya in English in a Japanese/Simplified Chinese Windows environment by running Maya with MAYA_UI_LANGUAGE=en_US.
mental ray  
MAYA-22357 Unified Sampling is enabled unexpectedly when bringing legacy scenes into 2014

In Maya 2014, if you open a scene from a previous version of Maya that renders using the mental ray for Maya renderer, your sampling settings are changed to use Unified Sampling. Some features, such as contour rendering, are not supported with Unified Sampling.
To render such scenes with their previously-saved legacy sampling settings, choose Legacy Sampling Mode in the mental ray Render Settings, Quality tab. The commands: setAttr "miDefaultOptions.miRenderUsing" 2; (Standard Legacy Mode) and setAttr "miDefaultOptions.miRenderUsing" 1; (Legacy Rasterizer mode) can also be used to revert to legacy sampling. New Presets are also available for Unified Sampling in the main Render Settings Presets menu, including: Preview, Production, FinalFrameEXR.
mental ray standalone  
MAYA-22487 mr standalone 2014 error: call to undeclared function "misss_fast_lmap_maya"

When rendering with mental ray Standalone 2014, if the following error appears during rendering: "call to undeclared function "misss_fast_lmap_maya", the "subsurface.mi" file from mentalrayFromMaya2014 (Maya 2014) can be copied into the mental ray Standalone 2014 installation, replacing the installed "subsurface.mi" file.


Instability when undoing quad draw on combined mesh

Maya can become unstable when using Quad Draw on combined meshes (that is, selecting multiple surfaces and choosing Mesh > Combine).  To improve stability, delete history on combined meshes before enabling Quad Draw.
MAYA-22162 Modeling Toolkit: Mesh Editing tools do not stay active upon file save

Modeling Toolkit tools (including mesh editing tools like Quad Draw, Multi-Cut, and so forth) are deactivated after saving a scene.  It is therefore recommended to disable auto-save while working with the Modeling Toolkit.

Multiple Representation  
MAYA-19686 Scene Assembly does not support File Referencing.
MAYA-21565 Manipulator handles on the active tool (Move, Rotate, Scale) are longer visible after Assembly representations switch.
Workaround: Reselect the tool.
MAYA-21592 Opening the Namespace Editor in scenes with large assembly reference hierarchies causes Maya to freeze. 
MAYA-22052 Cannot use Custom Scene Assembly render settings to render GPU Cache representations in Viewport 2.0 when the Background Reading GPU Cache preference is on.

Workaround: Turn off Background Reading in the GPU Cache Preferences.
MAYA-22055 Using the Python() MEL command with MFnAssembly methods may crash Maya.
MAYA-22088 Undo does not remove applied Scene Assembly edits.
Workaround: Use Remove Selected Edits in the List Assembly Edits window.
MAYA-22188 Scene Assembly does not support Animated sweep.
MAYA-22189 Scene Assembly does not support Animated Snapshot. 
MAYA-22191 Scene Assembly does not support motion path animation. 
MAYA-22222, MAYA-22446 Scene Assembly does not fully support set driven key data.
MAYA-22361 Scene Assembly does not support Character sets.
MAYA-22410 Deleting animation curves connected to assembly reference nodes or members may produce incorrect edits.


Hierarchical instantiated objects sharing shape nodes corrupt shading when 'duplicate special with graph' is performed on root.


Select all geometric objects in workspace, then run Modify > Convert > Instance to Object, and then duplicate w/ input graph.


Perform duplicate with input connections.

MAYA-11993 Incorrect coloring on wireframes for some ghosts

There is a difference between Viewport 2.0 and the default and high quality viewports - the rendering order in Viewport 2.0 is not the same as the old workspaces, and objects that are exactly the same may draw in a different order and may be drawn on top of another object. Animation layer ghosting is a common place for this to happen.
MAYA-14916 Marquee selection in UV Editor and Default viewport causes cascading artifacts with ATI Radeon 7970.

Workaround: Use driver # 8.980.0.0 from June 2012.


Default viewport only: Shading is incorrect after trimming an animation clip.

Workaround:Move the time cursor to refresh the shading.

MAYA-18481 The interfaces MPxVertexBufferGenerator and MPxVertexBufferMutator have changed, and plug-in writers who have implemented those interfaces must update their plug-in to the new interface.


"Default Texture Data" feature seems broken for plug-in hardware shaders (HLSL, CGFX, DX11).

MAYA-18501 Failure to switch between Viewport 2.0 and its render override, such as "viewRenderOverride", when running maqueeTool, which supports MUIDrawManager.

When running the scene view in overlay render mode, you may not be able to override your renderer.

For example, when running the marqueeTool from the devkit, when the marqueeTool plug-in is executed, you enter into overlay render mode. If you then try to override your renderer (by switching to a custom renderer via the Renderer menu), the heads up display still indicate Viewport 2.0 even though the custom renderer radio button is selected.

To work around this issue, refresh the scene view by tumbling the camera.
MAYA-18577 The interface to MPxPrimitiveGenerator has changed and plug-in developers must update their plug-ins to the new interface.

MAYA-20976 When running DirectX11 mode in Viewport 2.0, it is possible that the hardware device cannot be instantiated.
In this case, the WARP software rasterizer (*) is used instead. The use of WARP is indicated in the output window when the renderer is first used.
In addition, the heads-up display, which indicates the current renderer, also indicates that WARP is being used.

(*) WARP = Windows Advanced Rasterization Platform. Refer to the documentation from Microsoft for more details.

Note that WARP may not support the full set of features that a hardware rasterizer supports. This is more noticeable with the Windows 7 platform than with the Windows 8 platform.

WARP is currently not a qualified configuration.

You can also set the environment variable MAYA_FORCE_DX_WARP to 1 in order to always use the WARP software rasterizer.
MAYA-21640 Loading legacy 2013 Ext1/2 scenes that use MayaUberShader.fxo get shaders reset 2014

In Extension 1 and Extension 2 for Maya 2013, Maya used UI names instead of shader variable names for the attribute names of HLSL shaders (for use with DX11 in Viewport 2.0).
This is different from the behavior of other software such as 3ds Max, and therefore you may not be able to export your Maya file using FBX for use with 3ds Max.
This affects both your custom HLSL shaders and the MayaUberShader.fx/.fxo shaders provided by Maya.

In Maya 2014, Maya now uses shader variable names for attribute names for HLSL shaders.

If you attempt to use the MayaUberShader.fx or .fxo shaders from Extension 1/2 for Maya 2013 in Maya 2014, your attributes are automatically converted to use shader variable names; however, your shader settings will be lost and all values are reset to default.

To workaround this problem, add the following annotation to your shader technique:
bool VariableNameAsAttributeName = false;

As an alternative, you can also substitute your dx11Shader file with the version of MayaUberShader.fx/.fxo that is shipped with Maya 2014 to regain the shader attribute values.

It is recommended that you use the AutodeskUberShader.fx/.fxo files provided with Maya 2014 for new projects.


If your motion blur has no effect when an image plane is immediately behind a moving object, you can workaround this issue by setting the MAYA_VP2_OFF_NON_PE_FRAGMENT environment variable to 1. Setting this environment variable allows the image plane to be included in the calculations of all scene post effects, such as screen space ambient occlusion, depth of field and motion blur.


Marquee box and lasso lines do not display in Viewport 2.0 when ATI card is used on Mac OS X when "Line Anti-aliasing" is turned on.

Workaround: Turn off Line Anti-aliasing in the Hardware Renderer 2.0 Settings window.

Rendering in Viewport 2.0: GPU Instancing

Instances of plug-in shapes using MpxGeometryOverride may display incorrectly if they attempt to draw some instances differently than others by adding custom user render items, or using MRenderItem::enable(bool) to disable Maya render items.
There may be some lighting errors on instanced objects with non-uniform scales or materials with bump maps.
With AMD video cards in OpenGL mode, instanced objects with textures (in certain scenes) may randomly lose their textures.  Untextured mode still works correctly with GPU Instancing.  DirectX 11 mode on AMD video cards in Windows works correctly with textures.
Instanced objects with CPV-per-instance or UV-per-instance may display incorrectly.
GPU Instancing is not available on the Mac OS X platform
Instanced objects may not draw correctly when the Transparency Algorithm is set to Depth Peeling.

MAYA-16254, MAYA-17613 The behaviour of Maya's 'memory' command has been made more consistent. A side effect is that any script or plug-in that uses the command must be modified as follows:

1) Numeric results used to be returned in an array containing a single int or float value. Now they are returned as just int or float values, without the array. Therefore, code like this:

int $swaps[] = `memory -swaps`;

must be changed to this:

int $swaps = `memory -swaps`;

2) The -heapMemory/-he, -freeMemory/-fr and -physicalMemory/-phy flags used to ignore the unit flags (e.g. -kiloByte) and always return their results in megabytes. Now they obey the unit flags, and if none are specified, they return their results in bytes like the other memory flags. These three flags also used to return their values as floats. Now they return their values as ints like the other memory flags. To get results as floats, the new -asFloat/-af flag must be used. So code like this:

float $free[] = `memory -freeMemory`;

must be changed to this:

float $free = `memory -freeMemory -megaByte -asFloat`;
MAYA-17358 When scripting in Python, the function "os.path.expanduser()" returns different results when called from the GUI than from the command line (on Windows).

There are two workarounds:

1) Initialize the Maya environment within mayapy.

import maya.standalone

Now os.path.expanduser() returns the same value in mayapy as it does in Maya.

2) Set the HOME environment variable before starting up Maya. The value that it is set to is used by by os.path.expanduser() in both Maya and mayapy.
UI Architecture  
MAYA-19371 Maya CER now does not disclose the scene path/file name by default.

The default behaviour now is to not disclose the scene path/file name.
Set environment variable MAYA_CER_INCLUDE_SCENE_NAME as follows to specify the behavior you prefer:

0 (default) - scene name is listed as undisclosed
1 - include only the file name
2 - include the full path/file name
UI General  
MAYA-20637 The Maya file browser cannot open files with filenames that contain the characters "[" and "]".
To workaround this issue, use the OS native file browser. Select this option from the Preferences Window.
MAYA-12034 QT Crash - when clicking Attribute Editor navigation button

1. Add -ss (-skipSelect) flags to the shadingNode commands that create the new texture placement and file texture nodes. This will prevent the Attribute Editor from switching to them before the callback ends, as the nodes are not selected on creation.
2. add "evalDeferred( "select " + $fileNode )" at the end - this means that in a second, the new file node will be selected, and the Attribute Editor will switch to it (after the callback exits). This way, the Attribute Editor ends up in the same state as it would have been before.
MAYA-22469 Maya constantly executes "toolButton -q -ann $gNonSacredToolWidget;", making it difficult to read the contents of the Script Editor history.

moduleDetectionLogic refers to the new "autoloader" plug-in. Unloading "autoLoader" prevents the following commands:
loadModule -scan;.
