| Bug Number | Description |
| API | |
| Over 130 new classes have been added to the Python
API 2.0, including MPxNode, MPxData and much of the Rendering
API. Over 15 devkit examples are also available, and can be found in the devkit\plug-ins\scripted directory of the Maya installation. All Python 2.0 devkit examples are named with the prefix py. For more information, see the Maya Developer Help: Maya Python API 2.0 Reference. | |

The following section describes limitations, workarounds (where applicable) about this release.
| Bug Number | Description |
| Bifrost | |
| MAYA-32190 | The mental ray render for the BifrostLiquidMaterial will not match the viewport. Vorticity is not supported in the viewport and diffuse weight remap is handled differently by mental ray. |
| MAYA-32763 | The default value of 0.5 for Master Voxel Size may
be too small to generate voxels on some emitting meshes below
a specific scale, including primitives. For example, no
voxels will be generated for a default polySphere with
radius=1. Workaround : To generate voxels, either lower the Master Voxel Size or increase the size of the sphere. |
| MAYA-32869 | Bifrost scene is getting evaluated over and over
during batch render when runup is enabled.
Workaround: Disable Runup. |
| MAYA-33644 | Bifrost: Resulting Simulation motion seems
incorrect and seems due to Collision objects Conversion
Thickness. Fluid will react with a surface tension type behavior even when stickiness is set to zero. |
| MAYA-33828 | Currently, setting keys attributes found on the bifrostLiquidContainer is not a supported workflow. |
| MAYA-34114 | Bifrost will still render even after disabling the
display of particles and voxels in the Bifrost Shape Workaround : Hide the Bifrost object (set visibility=off). |
| MAYA-34177 | The default maximum particle viewport display number is set to 1 million. This creates repetitive looking patterns for higher resolution simulations. Respecting the limits of your graphics card, you can increase the number for a more accurate representation of the simulation. |
| MAYA-34412 | Self-intersecting attached mesh will fail to emit Bifrost particles |
| Cache Representation - Baked Geometry | |
| MAYA-31013 | Importing a gpu cache during a Windows remote desktop session will crash if the host system does not have Viewport 2.0 set as the default renderer. |
| Foundation | |
| MAYA-30309 | OSX 10.9: Hotbox and marking menus will not work on
second screen of a dual screen setup Workaround: under System preferences > Mission Control > [ ] Displays have Separate Spaces Uncheck the "displays have separate spaces" option. This will bring the OSX work spaces behavior back to the way it was before 10.9 |
| Localization | |
| MAYA-18046 | If you a running Maya in a Simplified Chinese environment, switch between the standard view and full-screen view of the current panels using the Ctrl + Shift + Spacebar hotkey. |
| MAYA-28299 | XGen does not support file names or file paths with
localized characters (that is, upper-ASCII characters and
double byte characters). As a workaround, users should avoid using localized user names. |
| Modeling |
|
| MAYA-39967 | Opensubd (Uniform or
adaptive): texture display may be incorrect if the mesh is
bound to a skeleton. Workaround: Use Maya Catmull-Clark Subdivision Method. |
| Multiple Representation | |
| MAYA-20004 | The Attribute Editor's texture sample preview will
show a broken swatch icon (red X) when loading a Scene
Assembly containing an object with a texture. Workaround : Leave it un-previewed. or set in the Maya preferences under the Display categories Max res. for swatches something larger than the estimated texture size. |
| MAYA-21592 | Attempting to open the Namespace Editor on a complex Scene Assembly scene (1000's - 10,000's of objects) will hang Maya for an undetermined period of time until the Namespace contents have been loaded. Namespace Editor workflows are not recommended for complex Scene Assembly Scenes. |
| MAYA-22088 | Undo after Reference/Scene Assembly Reference edits
have been made does not completely clear out the edits Workaround : Remove the zero'ed out edit by using the remove edits function. |
| MAYA-22191 | Attaching a Scene Assembly scene file representation to a motion path is not currently supported |
| MAYA-22211 | Blend shapes fails to function when used to create Blends between Assembly members and other objects |
| MAYA-22222 | Set Driven Key workflows are not currently supported when the Scene Assembly scene representation object is used as driver |
| MAYA-22361 | Character sets is not supported by Scene Assembly |
| MAYA-22446 | Importing ATOM of set driven key data fails on Scene Assembly |
| Rendering | |
| MAYA-16289 | When the Double Sided Lighting option under the
DirectX 11 Shader Attribute Editor is enabled, backfacing
polygons caused by negative scaling may turn black. Workaround : You should reverse normals after scaling negatively. |
| MAYA-24576 | When depth peeling is chosen as the transparency algorithm for Viewport 2.0 (in Hardware 2.0 Renderer 2.0 Settings window), MSAA can only take effect on opaque objects but not transparent objects. |
| MAYA-30985 | When both backface culling and GPU instancing is on, negative-scaled objects may show inconsistent culling result in VP2. The work-around so far is to temporarily turn off GPU instancing in VP2 option dialog. |
| MAYA-35665 | Older drivers for 1800M graphics cards may crash
Maya. Workaround : Please update to a newer driver. |
| MAYA-41781 |
Connecting a file texture to
mia_material_x_passes may cause color management errors to
appear in the Maya console. These may safely be ignored. |
| Scripting Python | |
| MAYA-17358 | "os.path.expanduser()" returns different results
when on the GUI on Windows. Workaround : 1) Initialize the Maya environment within mayapy. import maya.standalone maya.standalone.initialize() Now os.path.expanduser() will return the same value in mayapy as it does in Maya. 2) Set the HOME environment variable before starting up Maya. Whatever you set it to will be used by by os.path.expanduser() in both Maya and mayapy. |
| UI General | |
| MAYA-1688 | Auto-complete python commands in the script editor will run the codes inside a Python property block, not just returning the function/property list, but actually running the property itself. The same is true when you hit return to accept and fill that function/property in the script editor. |
| XGen | |
| MAYA-23962 | XGen is not compatible with merged meshes |
| MAYA-28065 | XGen: Clumping preview refresh issue When having a bad preview after altering clump maps, press preview again. |
| MAYA-35042 | Loading Xgen may crash Maya if fabricengine plugin
is installed. Workaround : Rename the PySide folder under the fabricengine install directory. |
| MAYA-36215 | Xgen Tube Groom requires tubes to have transformations frozen |
| MAYA-37306 | Mac OS X: Spaces are not supported for the project
name. |
| MAYA-37969 | Xgen and the geo that it is bound to have to be in the same namespace. It is not supported to import an XGen description or collection on a piece of geo in a different namespace. |
