Portal 2 Desolation: Tractor Beam Exterior

One of the models I've made for the ambitious Portal 2 mod, Desolation (https://emberspark.games/desolation). This started life as concept art by Hopper (https://hopper_8338.artstation.com), shown in the comparison picture, and I modeled and textured it to bring it into the game.
Modeled in Blender, textured in Substance Designer (yes, Designer). Rendered in-engine and in Marmoset Toolbag 4.
(Note: Original funnel model is only included for context - I created the exterior model specifically)
