Manually added light sources helped with shading.
We’ve already talked about how just how pretty The Order: 1886 is on the PS4, while the game lacked quite a bit when it came to the story that went along with the game, the graphics were among some of the best of the current generation of consoles. During Ready at Dawn’s Siggraph 2015 presentation the company touched on a number of techniques it used to bring the pretty including using an in house engine specifically geared this time towards putting out a game that would only be able to run on the PS4 and a PC.
The developer used this engine to put together their real time lighting solution, among other things. The fact that during cutscenes, there wasn’t any way to change where the camera pointed was certainly helpful when adding various dynamic light sources in order to add to the shading of the scene and therefore making it look more realistic. The company says that the light sources were actually all added manually, depending on where the developer thought it would make the scene look the best.
The company also released a couple of screenshots (which you can see below) showing the game running on a PC at 60fps. Ready at Dawn says that the target platform for the game was always going to be either PC or PS4 though their engine can be adjusted to be on just about any console if the tweaks are done right. The company had previously said and reiterated that the way they put the Order: 1886 together would have made it impossible to be hosted on another console.
