This may be a basic question but is there a way of making the internal network of the Sphere object visible with all the other nodes? I ask because I'm working on my planet and my Sphere object has two separate water shaders attached to it - a normal one and a 'tropical' one. I'd like to blend the two partly based on altitude but to do that, I want to connect up a Surface Layer with one of my already existing Compute Terrain nodes. Unfortunately, my Compute Terrain node is not on the same level so I can't.
I suppose I could get around the problem by using a Texture Coordinate from XYZ node but I'd like to know this for future reference anyway. Any help would be appreciated.
EDIT: Luckily I managed to get the effect I wanted without requiring altitude but still, it would be nice to know how to make all nodes visible in one level.
