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.
