Thank you, that worked. The help file led me to believe that
"distance" was only for type 1 fog.

Just for a try. Does 'inverse' to the plane resolve the problem as well ?

Curiously the Scene Help doesn't mention that fact in the section The Sky
Sphere or the fog sections either from what I could see there.
I hate to lead people astray like that, sorry. Glad you corrected me
Thorsten.
I still use sphere instead of sky_sphere so much it's second nature to add
hollow to that anyway. Guess when I make the mistake and get the error when
putting hollow into one that I don't think twice about it and remove it.

Shouldn't. The normal of a plane isn't flipped when the float is negative,
only when the plane normal itself is negative. Inside and outside of a
plane remains constant otherwise. Unless I'm wrong about that too.

You may be suffering from one of those misconceptions that Warp has
been talking about. A sky_sphere is not a sphere object. It is more
like the background feature that has spherical pigment properties.

Perhaps it could be a good idea to actually TEST the suggestion between
posting it. :)

Ever considered using 'inverse' instead?
If you don't inverse your sky sphere you will be looking at its surface
from the inside and thus the normal vectors will be pointing at the wrong
side producing a possibly unwanted result.

Sage advice, thanks Warp. I'll certainly try that.

Yes, well I do when I'm 50% unsure. I was 99% sure hollow went into
sky_sphere.
