In the creation kit in the world spaces tab it looks like you can load up .dds files but I always get invalid direction when I try to load them.

Anyone here successfully loaded a dds file as a map file? It is possible to quickly edit a dds file and load it into the creation kit for faster map editing?

My goal is to create a large brand new world just to walk around in, and overtime add more content to the world. Any advice you could give?
