Here is my zip to generate a 360 x 360 degree view of a lake that I mapped to a Sky Spere via Cube Mapping

I had some trouble with Cube Mapping and Rich Helped me out. Here are the Key Points.

Front, Back, Top, Bottom, Left, Right

Without seeing the textures you're using I can't comment further. The textures should be a uniform size (i.e. 256x256 or 512x512) and should be applied to the object in the correct sequence as above

In Addition I came accross this excerpt from a book on Nvidia Cg graphics that add some usefull info, be patient it is quite slow to load, but worth the wait

Hmmm, interesting effect. If you edit each image and get rid of one pixel blue margin along top and down side, it will get rid of those annoying lines between faces.

Pity you couldn't get a fully seamless design between all faces.
