Minimal app

So, this has been asked a few times already in the past, but I can't really find anything which actually works. What is the absolute minimum you need to create a blank screen (and possible enable access to the editor) based on the Torque3D executable and a minimal amount of scripts? I tried to create a GuiCanvas in main.cs, but for some weird reason this completely crashes the app without logging any errors to the console log. Are there any required hooks from the actual engine to script functions which absolutely have to be present?

There was a recent set of tutorials, but those are specifically for Torque2D and appear to not work on Torque3D. There's also word of a 'Blank template' but that doesn't seem to be available.

Thanks!
