Hey there! All of our tooling is set to the most recent master in Babylon, aka 5.0 preview. We don’t have version numbers on our tooling so currently there would be no way to get the state from 4.2.
Also from a dev standpoint, we have talked about if we should start introducing version number on our tooling. Particularly with the GUI Editor, and future tooling we create. It’s not something I think we intend to do at the moment but the thought has come across.
Is there a reason you are using 4.2 over 5.0 preview? If you try 5.0 does it work?
This begs the question on what is being generated on the newer version that 4.2 doesn’t like? Should be backwards compatible.
