Excuse my ignorance but is there a sky sphere fuction in Moray like in POV
Ray? If not what would be the best way to handle this? If a large sphere is
used what diameter would be good.

Also does Moray have a Looks like feature for making lights look like
shapes, as POV Ray has so you can make a cylinder light?

thanks

Mitch

Wou;dn't this rely heavily on the overall scale of your scene and 
the "look" you require?

As to how best to handle it, wouldn't that also depend on how you 
want your scene to look again?  Nighttime?  Day?  Realistic? 
Stylized?  There a re a lot of options here... including creating 
  little media clouds or even CSG clouds with partial transperent 
textures (which could have a cute candyland kind of appearence 
while obviously not real still lending to the overall look of the 
image) instead of the usual paint them onto the sphere look most 
people turn to.

Most people create a sphere and texture the inside with various 
noises to simulate clouds and blue sky, sometimes sunsets.

I'm not looking at the pov docs now but I believe that the old docs said
that the povray skysphere was equivilant to a sphere about 10,000 units in
radius. Anyway thats what I use in Moray if I need one. But like Dearmad
said it can also depend on the scene.

  Not really. If you have an object at 11000 units away, it will be behind
your sphere, but not behind a sky_sphere. Not even if it's 1000000 units
away. Or 1000000000.
  Another difference is that sky_sphere is not traced nor shaded in any
way (and thus is faster).
