Still have to thank you redbox! That got me going.
Together with a spheremask updated trough a parameter collection to get the inside shading. And a fresnel for the dome edge…
I’d like to have a bit more control over the depth fade though, maybe i have to play around with it a bit more.
I’d like to have a small contour line, now it often gets thicker depending on the angle of what is behind i think.
