Arkyss, Welcome to the Guild!
But don't give up on DD3 or CC3. I use them exclusively, and I have been redoing the maps for Wizards' Mods.I have so far done THUNDERSPIRE and PYRAMID OF SHADOWS and almost finished TROLLHAUNT. Soon I will Start the DROW mod. All of them were done with just DD3 and BITMAPS and the odd inserted image from another source. Nothing more really.
