Maya LT 2015 Extension 1 is now available!
We are very happy to announce the first extension release for Maya LT 2015.

If you subscribe to Maya LT through Steam, you should automatically get the new features and fixes when Steam updates the build. If you have auto-updates turned off, we definitely recommend that you download this update (we also had a Heartbleed fix May 2nd, so you want to get that as well).

What’s new in Maya LT 2015 Extension 1?

Game Exporter
The new Game Exporter simplifies how models and animations are exported from Maya LT for use in game engines. The Game Exporter allows artists to define ideal export settings and have them preserved the next time the file is opened, improving consistency in export. Artists can define multiple animation clips within the tool by giving each a name along with a start and stop frame. The defined animation clips can be exported as multiple FBX Takes within a single file, or as multiple FBX files. The export settings, animation clip list, and set of objects to be exported are preserved within the Maya LT file to simplify future editing and export. This tool makes it much easier for indie game makers to animate multiple clips within a file, review animations, and export animation clips to a game engine.

Added Set Driven Key
Set Driven Key within Maya LT lets a user drive animated motion in one part of a scene through another object in the scene. This makes it faster for game animators to repeat tasks that are more complex in less time, since repeated movements within a scene can be linked together. Set Driven Key also improves interoperability with certain auto-rigging tools, making it easier for Maya LT users to leverage those tools to create their character rigs.

Rigging Utility Nodes
New utility nodes in Maya LT let artists finely tweak and adjust their character rigs and animations in the node editor. The utility nodes provide the ability to add mathematical adjustments to existing relationships between objects in the scene, helping to give riggers and animators better control over their character animations. The new utility nodes also make it easier for artists to use auto-generated character rigs.
