If you install either the 1gig or 4gig memory mod that gives extra memory access to either Il-2 or the map maker version, you can make and save actors of almost any size without the program crashing.

I´ve made actors up to 10mb in size without having to split a map into geographical parts and then recombining all the separate small actors into one final actors.

Mind, if you prefer to make smaller actors and combine then afterwards, then that is up to you of course. Every one uses whatever method works best for them.
