Note that the master branch is never the most up to date branch. Instead see https://git.benetou.fr/utopiah/text-code-xr-engine/branches for an overview. To explore branches in VR see https://fabien.benetou.fr/pub/home/future_of_text_demo/engine/branches.html
In order to have a better view of the different features accross branches see https://mastodon.pirateparty.be/web/@utopiah and https://twitter.com/utopiah/ which act as a kind of live documentation of the process.
