Question about custom objects

How do you use objects from mods in the Worldbuilder? (For example, a T-34 wreck)

You gotta make sure that the correct mod is mounted on Worldbuilder start. Check the debug window. It usually loads in alphabetic order so just move any .module files that are before 'E' out of the COH folder (later move them back ofc.)

Ok thanks, it was loading Battle of the Bulge. That also explains why all the trees were snowy.  :)

Is it possible to make a custom upgrade that could use the D,E,Q Keys to activate it seeing as how the up down left right are taken?
