Autodesk Maya LT 2016 Extension 3 Release Notes

Important Notes

This section provides important installation information about this product:

Maya LT requires a license of its own, you cannot activate it with a Maya license. Without a license, you can activate it in trial mode.
Maya LT can be installed alongside an existing version of Maya. Preferences folders are distinct.
Maya LT 2016 supports two licensing methods, User license and Stand-Alone license. For more information about installation and licensing refer to the installation sections in the Maya LT online help.

NOTE:Maya LT 2016 Extension 3 on Mac OS X launches an AdSSO process. This process may hang if the location where the AdSSO Application is installed is unmounted while the process is running. It is therefore recommended that you install Maya LT on the local hard drive and not on a removable device. If the AdSSO process hangs, you can terminate the process using the Activity Monitor.

Known Limitations

NOTE:Unless otherwise noted as fixed, this release also contains the same known limitations listed described in the original Maya LT 2016 release notes. (See link below.)

Bug Number	Description
Animation
MAYA-67189	Quick Rig does not support NURBS.
Color Management
MAYA-57730	File nodes created with the 3D paint tool's Assign/Edit Textures functionality are not color managed. Workaround: Create the file node using the Create Render Node window.
Interoperability
MAYA-61009	The FBX plug-in triangulation option was previously implemented so that the resulting triangles in an FBX export would match exactly that of Maya LT's Triangulation tool. This logic introduced scene corruption problems; therefore the plug-in's triangulation has been reverted to always use the legacy FBX triangulation algorithm. This legacy algorithm doesn't produce incorrect triangles, just different ones. Use Mesh > Triangulate in Maya LT. Export using FBX export, and in the Export window, deselect Triangulate (under the Geometry options). Delete the triangulate node that was created during the triangulation process. You can do this using the command (for example: delete polyTriangulate1), the Node Editor, or by selecting Edit > Undo. If you prefer that the FBX plug-in continue to use the algorithm that produces Maya-style triangles, set the MAYA_FBX_ENABLE_MAYA_TRIANGULATION environment variable to any value. NOTE:Use this environment variable at your own risk, as scene corruption problems may result; for example, the shading assigned to objects may be removed.
Modeling
MAYA-62589	Blend shape targets using Tangent Space don't import correctly inside Mudbox
MAYA-64674	When drawing a curve using the Bezier Curve Tool, the first and last handles are not selectable and appear as gray when Viewport 2.0 is in Core Profile mode. Workaround: Use DirectX11 or OpenGL - Legacy mode.
MAYA-65042	For scenes with hundreds of blend shape targets, opening the Shape Editor may be slow.
MAYA-65148	Shape Editor's Export/Import doesn't support combination targets. Importing an exported combination target will result in target drivers not being linked to their combination targets. Workaround: Add target drivers to the combination target once the targets are imported.
MAYA-66411	Sculpting disappears when turning Edit mode off in the Shape Editor after saving/reloading a Maya binary scene file. Workaround: Edit the target before saving your file.
MAYA-66436	In-between targets are not exporting/importing using the Shape Editor's export/import options.
MAYA-66457	Blend shapes work incorrectly when a single target is created for multiple objects and edited with sculpting tools.
MAYA-66908	Freeze and Mask strokes disappear after adding a target, using the Mask Target Tool, then disabling edit. Workaround: Toggle the Show Frozen tool setting for sculpting tools to refresh the freeze and mask display.
MAYA-67113	For blend shape targets (including in-between targets) that have physical meshes that already exist in the scene, use sculpting tools either directly on the target mesh in the scene or directly on the base mesh. Avoid activating the sculpting tools when both the base mesh and physical target mesh are selected in the scene, or you may run into viewport refresh issues. If your base mesh doesn't update after sculpting on the physical target in the scene, simply exit the sculpting tool (switch tools) or scrub the timeline to refresh the viewport.
MAYA-67532	Masks don't update after flipping or mirroring targets in the Shape Editor.
Turtle
MAYA-53946	Ambiguous short flags in the ilrTextureBake and ilrVertexBase commands in the Turtle plug-in have been replaced with unique short flags as follows: command ilrTextureBake -dr short for -directory (was -d) -dsp short for -displacement (was -d) command ilrVertexBake -slm short for -selectionMode (was -sm) -spm short for -samplingMode (was -sm) -fsp short for -filterShape (was -fls) -fs short for -fullShading (was -fls)
Viewport
MAYA-66934	When drawing with the Joint Tool in wireframe mode, the Snap to Projected Center functionality may not work as expected. Workaround: Option 1: Set the environment variable MAYA_VP2_USE_VP1_SELECTION =1, then select OpenGL - Legacy, OpenGL - Core Profile (Compatibility) or DirectX11 from the Rendering Engine drop-down list in the Display preferences and restart Maya LT. Select this option if you want to continue to work in wireframe mode. Option 2: Set the viewport to shaded and X-ray mode (for example, Shading > Smooth Shade All and Shading > X-Ray).

Customer Involvement Program (CIP)

The first time you start Maya LT, the Customer Involvement Program dialog box appears. If you choose to participate in the Customer Involvement Program, Maya LT automatically sends Autodesk information about your system configuration, what features you use most, any problems that you encounter, and other information helpful to the future direction of the product. For further information, see http://www.autodesk.com/cip.

Customer Error Reports (CERs)

We are able to improve the stability of Maya LT largely because of the Customer Error Reports (CERs) that users of our products submit. We thank you for taking the time to fill out these reports and ask that you include as much information as possible about what actions you were performing at the time the error occurred. These details raise the value of the report immensely and are very much appreciated by the Autodesk Maya LT Engineering team.
