empty room 3d model

3D environment model of an empty, rectangular room interior. The focus is on clean architectural geometry. All walls, the ceiling, and the floor are smooth and barren, without any furniture, decorative objects, fixtures, windows, or texture details. In one of the main walls, there is a distinct, clean-cut rectangular doorway opening that goes all the way through the wall, but there is no door frame and no door installed in the opening. The view looks into the room from a corner perspective, showing the bare floor extending towards the empty doorway. The room is illuminated by neutral, ambient studio lighting that highlights the corners and edges, casting soft shadows. The background outside the doorway is also empty and neutral. Optimized geometry, clean topology.
