Hiya.
Unless the next version of A7 has a blow-my-socks-off terrain/in-game editor...I think Conitec should create a direct, fully-featured plug-in with the GROME terrain editor (
http://www.quadsoftware.com/index.php?m=section&sec=product&subsec=editor ).
GROME
does list "3D Game Studio" as the next-on-the-list for import/export...so maybe this is already in the works. I just wanted to specifically voice my request/support for such a plug-in.
PS: No, I don't own GROME...but there's a good chance I will by, say, tomorrow...I need a new terrain editor ASAP, and GROME already supports one of the engines I'm contemplating using (Torque).
