Two very technical The Order: 1886 documents have appeared online going very in-depth in to the next-gen tech creating the game on PS4.
The Order: 1886 screens show new PS4 technical… stuff
The two documents are a paper called “Crafting a Next-Gen Material Pipeline for The Order: 1886″ and a slideshow presumably to support presentations. The crux of it is that in order to create something that really looks next-gen Ready At Dawn need a way to make highly detailed materials fast and efficiently to enable their artists to create in-game assets quickly. That include 3D scanning cloth as well as creating a library of materials.
You can read the paper here (big, impenetrably hard science stuff) and see the presentation (pretty pictures) here.
