This engine looked promising however I see the forum is inactive with posts mainly by NRG and none that I could see after 2022. I did join the Discord channel and it was stated their that the engine is not dead and work was proceeding on it. I like the editor GUI and the fact that it looks easy to import full scenes in Collada format.<br /><div>The Google playstore does not have a version of NRG available (in Australia at least) so I downloaded the .apk from this site. When I tried to install it on my Android tablet I kept getting messages about the app being made for an older version of Android and it being a security risk.<br /></div><div>Is the engine/editor still being worked on? And when may any updates be available?<br /></div>Thanks

Yes the last publicly available version is dated from late 2022 early 2023, however tons of work have been done since then it is closed to public due to its dependency with a AAA game that we are currently producing. Once the game is released the version will be available to the public shortly.
Take note that the new release will still be backward compatible so, in the meantime feel free to download the current public version.
