To create a sky dome i first started off with a geosphere and enlarged it over the entire scene, leaving a little room around the sides to ensure that the sky dome covers the entire plane.
I then ticked hemisphere option to reduce the sphere to only cover that top as the bottom is not required.
After this i flipped the normals to ensure the sky material I used would show on the inside of the dome as opposed to the outside.
I then added a xform modifier to the sky dome to allow me to use the gizmo to reduce the hight of the sky dome as, as we have been told in lectures this makes it look more realistic.
Finally I added the material take from the VLE to the skydome to get the following effect.
I am pleased with the outcome the sky dome looks realistic and passes for sky, there is a slight seam where the texture meets but it does not seem to be entirely noticeable so I will stick with it.
