Today Autodesk have released the 2019 edition of both Maya and the stripped down indie edition, Maya LT. The big theme of the 2019 release is performance, with 2019 having performance improvements across the entire application, from start up and selection speed, to animation playback improvements. This release also includes tools to better track how Maya is using your computers resources, including Evaluation Toolkit and Profiler, which should help you track down bottlenecks to your scene’s performance.
Details from the Maya 2019 release notes:
This release focuses on letting you work faster than ever before through new workflows and numerous performance enhancements.
A myriad of improvements to Viewport 2.0 enhance its performance when doing everything from loading scenes to selecting objects, to handling dense meshes.
Additionally, cached playback speeds up your ability to preview animation changes by intelligently redrawing only what’s changed rather than updating the entire scene. This greatly improves viewport playback performance, removing the need to constantly playblast your scenes.
This release also gives you the most powerful tools yet for tracking exactly how Maya is using your computer’s resources. New features in the Evaluation Toolkit and Profiler allow you to pinpoint exactly where there may be inefficiencies or problems that are slowing down your scene.
Improvements to Render Setup enable you to better organize your render layers by coloring and isolating them in the Render Setup editor, or by controlling whether lights are included in each layer by default. In addition, more options are available for exporting and importing scene Render Settings and AOVs.
You can also now render Arnold right in the viewport, including all its RenderView options such as Debug Shading, AOVs, and region rendering.
New Graph Editor filters have been added to help you refine animation curves quicker and easier than before.
Plenty of examples and presets have been added to the Content Browser covering a variety of areas, from motion capture, to motion graphics, to characters. Use them as-is, or as a jumping-off point for your own work.
This covers just the top level new features, be sure to consult the full release notes for more information on improvements in the 2019 release:
