The Death Star was a huge spherical battle station 160 kilometers in diameter and thus only a very small section was shown in the Star Wars films. I have adapted the general feel and created what I imagine a small section to be, positioned just above the Ion Sub-light Engines.

I have also included the Droid K-2SO from Rogue One for authenticity. K-2SO loads into the scene automatically, but you can also go to Props/Shredder/Droid_K-2SO and load him separately.

Should you wish to dial down the glossiness of the droid just open the Surfaces TAB and adjust as you require.
