The attachment is a compressed single material file (mz5) that you save anywhere in your Runtime/Libaries/Materials folder, deleting the .txt file extension. I'll post a 91x91px PNG thumbnail for it in a minute.

 

For those not familiar with applying materials to an object, this is what you do. Load and select your EnvSphere or hi res sphere, open the Material Room, find the shader where you saved it in your Library Materials folder, and double-click it. The shader will load into the sphere material, and you'll see the four control nodes top centre.

 

If using a hi res sphere, scale it up to 180,000% (for the benefit of those who use a comma instead of a decimal point, that's one hundred and eighty thousand percent). This makes it nearly 750ft radius. Untick the "Casts shadows" option in the Properties palette. Do not use the render option "Remove backfacing polys", or you won't see it in your render. You wouldn't need to worry about this stuff if you used bagginsbill's EnvSphere.
