I'm sure some of you are already aware of this, but the solution was never properly publicized on T3A. This is just to make sure it doesn't get lost some day.
When trying to import certain high detail models in 3ds Max 8 (such as several large structures and ultra-quality CaH models), you'll get the following error:
Runtime Error: Out of scripter memory- use options to increase
In order to increase your scripter memory, press F11 to open the Listener window, type 'heapsize', press enter, and then type 'heapsize += 10000000'. This should give you plenty of scripter memory to import BFME's heaviest meshes.
