Material Elements, how do I make them work?

I have a planet Earth which has 3 material elements, but I can only see the first element on the Earth mesh. The second element is the clouds mat, and the third is a blue hue. Do I need to turn the 2nd and 3rd element on, somehow?

does your mesh consist of 3 spheres with varying radii?
if so then the 2 outer layers need to have a material applied to them that somehow supports transparency. in your case probably translucent or alpha for the clouds for example.

In my opinion, it would be better to just have it all as one material.
Here’s an example that I managed to make, which I assume is similar to what you’re trying to achieve, but it’s a single mesh and a single material.

Here’s the material zoomed out, hopefully you can get a rough idea on how it works even though you can’t see much.

Thank you divi and bogieman. Bogieman, I really wish I could see the blueprint at a larger scale. Is there any chance you could post it larger, or in 2 parts? Thank you so much!

No problem, made a tutorial thread, hope it helps

Beautiful. Thank you.
