Facing problems with skybox

Hello! I am trying a create a game with two modes- easy and hard. At first I created the easy mode scene, then duplicated the scene and tried to change the shader of skybox. Whenever I change the shader of skybox in one of the scenes, it automatically gets changed for the other scene as well(which I don’t want). Can you please let me know how can I have two seperate shaders of skybox in two different scenes?

Wich version of Unity you are using? You probably are changing the material (Skybox) instead of replacing it on the scene with a new one.

Duplicate and rename the shader. Have shader one for 1st scene material and the other for 2nd scene material. Then changes will work fine.
