I noticed that in many custom maps there is a dark area of terrain surrounding the player so I took a quick look at the problem and the answer is simple!

note: the flowing may not b correct but it looks better than a dark patch

In Zeroeditor when in the texture mode there is a box below "Texture:" that says "Detail:" just type in the same texture name as the main texture u r using on ur map! (and save, munge, etc)

Hope that helps ya. Make sure to participate in the poll!
