  2. Right Click the Hierarchy tab and go to 3D Object. Click on Sphere
  3. Right Click the Hierarchy tab and go to 3D Object. Click on Terrain
  4. To change the level design of the terrain, I went to the Inspector tab and clicked the brush on Terrain to form mountains.
  5. To change the color of the objects, I right clicked the Assets tab and hovered over Create and Clicked on material. I changed the color of the material and dragged it to whichever object I wanted to.
  6. To change the Skybox, I clicked on Main Camera in the Hierarchy tab, and on the Inspector Tab, it says Clear Flags in the Camera Component. I clicked on Skybox and changed it to solid color.
