I know all of these threads are old, but I just wanted to add to this that the standard XCC Mixer pack in fact
includes a TD map editor. It's simply called "XCC Editor"
The easiest way I found to set it up is this:
-put the same mixfiles CCMAP uses (desert, winter, temperate, conquer) in the XCC directory
-in XCC mixer, go to
View ->
Directories and set the Secondary TD directory to the XCC Mixer directory.
-start "XCC Editor.exe"
