The MuJoCo Plugin and Unity Integration package is now released. See download page and new chapter in the documentation. It allows you to import MuJoCo models in the Unity editor, adjust their visual appearance, and then generate Unity executables that either simulate the model locally or provide remote rendering for a MuJoCo Pro simulation running outside Unity. The package contains several demos. This software will be developed further. Some of the future developments are discussed at the end of the new documentation chapter. User comments would be particularly useful at this stage.
