Color select region on pawn

So I made a rotating sphere static mesh pawn that I am trying to make into a region selector for a game menu. I followed part of this tutorial Blueprint Making a 3D Puzzle Game | Live Training | Unreal Engine - YouTube to get the pawn moving with the mouse cursor and all that works fine. I would like to be able to select the different colored regions on the texture for choosing levels but also have a better looking planet with mountains or water on top of it so the color id texture isn’t seen by the player. My question is how can I select the color regions to bring up a UI with level stats and could I just add the high res planet in the components window of the blueprint viewport to have it follow the sphere’s movement?
