Have not received my Disc of DD3 yets so I have not tried making a dungeon Map with DD3 yet.
Just got my Disc of CC3 and starting to use it.
I was one of those that never got the Online Download to never work
I do believe that the size of files used in Dundjinni and DD3 are different
DJ is 200x200 for 5 foot and DD3 is 300X300.
