So my first 2019 self-challenge was to find a large epic 3D environment with super detail and texturing and try and recreate it with the skills I've learned this year, before I start my own. I chose one of my favorite 3D artsists, Toivo Huhtaniska, and his "Heart of the Industry" piece that recently melted my face! (see it at: https://www.blendernation.com/…/behind-the-scenes-heart-o…/…). IT still needs a RR car I have to model and texture. I still haven't officially lighted the scene yet, still just an HDRI. A couple objects' render icons were disabled and didn't show up, so still some work to do but wanted to share it. This has been an extremely rewarding self-challenge project, on to my own original... O_o
Looks amazing David! Personally I would make the top windows a lot less saturated.Probably some of the windows need to be broken. And the rails and the wood and stones under the rails darker. And where does all the light come from? The bottom of the scene looks as if it's in the open. Well you said the lighting isn't ready;)
But for the rest: I really love work like this! How long did this take you?
