I am trying to use sky box. When I try to load a sky box of single texture in the terrain editor, nothing shows up. I have tried making the image up side down, but, the screen remains black. I 've tried with the following 2 images.
How the textures should be arranged in a single file?
You need to save it as a DDS file check this tutorial

Another solution is to split it in 6 separated images.
Thank you for the link.
Q1. Do you know any other way to convert cubemaps to Vertical Cross, except using the action file(that’s incompatible). I shouldn’t do it by hand, it might create seam.
Q2. Why only take DDS for a single texture?
Q1. It shouldn’t create seams if you cut to the right pixel. I don’t know any software that does this
Q2. afaik it’s the only format that supports cubemaps. A cube map is a stack of 6 textures really, stored in a single file.
DDS also bring the DTX compression that is very valuable since the GPU can decode them on the fly, which means the texture is store compressed in the GPU memory.
Also you won’t see any games using directly textures like you posted because the black areas are a waste of memory.
After some google search I found a tool that cuts one images into six individual images. Its called, Vu2U, found here
What do you suggest, should I continue using 6 images or should I compress then into one DDS?

depends on resolution dds without alpha can be 4 to 8 times smaller in memory usage than uncompressed textures.

I'd go for DDS
