I think darkmod can overcome dromed limits I'm wrong To create 1 room in dromed you need one brush,to create one room in DR you need 6 brushes 8201 brushes / 6 = 1366.8 + 1000 brushes (thats used like patches in DR) = 2366 + 500 (as models and entities) = 2866 in dromed,so you didn't get any optimization errors with that number
