[2020] My weapons screen background was the room they used to reference it

You are really seeing behind the scenes here. Ill give you some insight.

Thats the image based light probe we set up for the scene and captured. In exterior scenes its revealed as the skydome. It contributes to the lighting of models in that scene and grounds them into the shot. If you were able to turn the camera 180 you would see the gunbench scene in the image:) The objects behind the gunbench use a photo projection technique commonly used in movies. This was used in the charcter selection scenes also.

The perk packs are physical props that we built in house and captured at the studio. When it comes to assets like that we use a neutral stage so the capture comes out as clean as possible.

LOL! Shame comment:)
