From 2019.3 onwards the 2D Animation package is out of preview and verified. This means that the 2D Animation package is stable and will receive regular bug fixes. We will continue to add new functionality and these features will be clearly marked as experimental to distinguish it from the more stable features. Overview The 2D Animation package adds tooling for rigging a sprite for skeletal animation. This package includes a Skinning Editor module in the Sprite Editor window for creating and editing bones, manual & automatic mesh tessellation as well as skin weights generation and painting. The Sprite Skin runtime component ties this all together to drive sprite deformation. This also includes support for Multiple Sprite Single Character rigging workflows through 2D PSD Importer Package. Experimental Features This package also includes experimental support for Sprite swapping workflows. Getting Started Install latest Unity 2019.3 Open Package Manager by going to Window > Package Manager Choose 2D Animation from the list and click on Install at the bottom right of the Package Manager window. Optional Install for Improved Performance The performance of the 2D Animation package in 2019.3 can now be improved with an optional install. What is it? This release optimises performance for high bone counts (this includes current performance gains for complex Sprite meshes with high vertex counts). Animated Sprite deformation at runtime will get a performance boost by installing the Burst and Collections packages from the Package Manager. This allows the 2D Animation package to use Burst compilation and low-level array utilities to speed up Unity’s processing of Sprite mesh deformation. Getting Started Install Burst 1.1.2 Under the Advanced menu, make sure that the Preview Packages option is check Install Collections 0.1.1-preview Check Experimental Enable Note: As the implementation of the performance boost might contain bugs, you can have any Sprite Skins switch back to the previous implementation by clearing this option in its component settings. With the packages installed, the Experimental Enable batching setting becomes available on the Sprite Skin component. As the implementation of the performance boost might contain bugs, you can have any Sprite Skins switch back to the previous implementation by clearing this option in its component settings. The package is currently tested based on Burst version 1.1.2 and Collections version 0.1.1-preview.
