I have a doubt, can we really make a game in unity and import to babylon using Babylon Toolkit?.
The babylon.js toolkit is handled and maintained by a community member (Mackey24) who seems to have disappeared since a few months. So I have no idea what is the current status.
He created a website https://babylontoolkit.com/
So perhaps you can reach out to him there?
Sorry to hear that. Please try to ping Mackey as we are not maintaining his toolkit
