This is done 100% on Substance Designer and Render in Unreal Engine. I am training my capabilities on Substance Designer and now adding the Unreal Engine. I know this approach it isn't (yet) the usual but I just need to dive full on into Substance Designer and as any 3D artist we need to do sci-fi, so no better to use the game that had influence me and almost all the 1st person shooter games out there with the 1st Doom.
I used a mix of 2 concepts the corridor from Jeremy Thurman ( https://www.artstation.com/artwork/ByZP4) and the door from Colin Geller ( https://www.artstation.com/artwork/eZenG ) and give a little bit more of my interpretation by mixing them both.
I hope you like, feel free to drop a comment, and if you want to see I build it just drop a message and gladly tell you :)
