Are any plans in the making for sky sphere support for Moray?  Working
with the excellent texture editor included it would be very useful.

I have found that scaling a normal sphere uniformly by about 5000 units
works pretty well.

 Another useful trick for certain situations is to scale it non-uniformly.
A little fog with a distance of a few thousand units also adds to the
realism.

Agreed... 90% of the time, with any cloud texture, a "sphere" that is a lot
flatter than it is wide looks much better.... scaling of 5000, 5000, 2000 or
so....

On the otherhand, a gradient sky with no clouds can have almost any scaling..

But the thing is,, how do you keep shadows from forming on it and also there
is some times that you really cant use a sky sphere such as with certain
starfield include files,, some stars get caught behind a sphere,, it
wouldn't be that hard to impliment,, I think it would be a goodd Idea to
have

As far as not having shadows on your real sphere for a sky use
ambient 1 diffuse 0. With diffuse 0 it will be shadowless.
