I'm gonna talking bad like always :

Don't take it too personnaly :

it's a very basic tool and it's really bad : not a real editor for roads and others things, very very very far from BV engine road editor.

And you put : "Free for non commercial use" let me laught ,
generally people put that if their product is something really
good , not for simple or lonewolf bad things.
who you think will use such thing for any commercial purpose ?
stop dreaming nobody will use it to make something to sell.
