For that matte painting ( pic A ) , I first sketched a few ideas basing on the plate ( pic B ) as reference for my composition . I choosed one , opened it in Cinema 4D and tried to find the camera position and focal that matched the perspective . Once I got them , I began modeling the city ( pic C ). CG is always useful when creating such an environment cause it s all about repeated patterns in perspective and it really helps for keeping accurate . I rendered a few pass like diffuse , illumination , radiosity , ambient occlusion and assembled them in Photoshop . The background was a combination of various pics , including one of the Lax Airport restaurant Tower for its futuristic look .
