I made Sci-Fi chambers using some old models I had made while working with Wings Intellect, which were never used and I was permitted to use when the company got shut, although it took a while to re-texture some and model some small pieces anew.

 

The scene contains 2 chambers; a controlling chamber and a bigger hall housing 2 large size generators. It has many lights set up. The lights and the visual lighting materials alike, can easily be toggled and tweaked with the help of Blueprints.

 

 It is compatible with the latest UE4 updates and is available on the UE4 Marketplace here: SciFi Chambers Environment Set

​

It is also available on Unity Asset Store, compatible with Unity 2018 and higher over here: SciFi Chambers Asset Pack
