Attaching objects to a spinning sphere

I’m trying to build a simple spinning planet with mountains, forests, and clouds (not earth scale, mario galaxy scale).
I’m very new to UE and cannot figure out how to attach objects to the spinning planet. Grouping them does nothing, I’m trying to find a function like “constrain to parent” in maya … what’s the equivalent of that in UE? Am I approaching this backwards, and should be building the world asset in blender or something first?
