This is where i am currently.
Just a sphere with cool colors 
Here is my overall material…
and zooms !
edit : The soft Particles nods are not linked because I learned that when you put you material in translucent it deforms the mesh badly… If anyone have a solution for that i’d like to hear it !
I want to make a cool decal like in this post :
but in Unreal.
i’ll search for it tonight.
