Pinching in a ProceduralSky material, what to do?

Question

Hello! I tried looking this up to no avail, I think I’m missing something obvious in the editor but I can’t find a way to deal with this.

When I make a ProceduralSky material, it always has very evident pinching at the top.

Is there a way to deal with that?

Ideally something that doesn’t involve converting the ProceduralSky material to a shader and mapping it to Cartesian coordinates - I feel there has to be a setting somewhere in the Inspector for that, but I can’t find anything.

Thanks for the help!
