submarine interior 3d model

Create a circular submarine interior designed for item placement and player interaction. The sub should have a single central floor platform dividing the space horizontally, with curved walls forming a full circular hull. Include one round porthole window on the upper wall facing outward, allowing dim blue light from the ocean to filter in. The environment should feel enclosed and metallic, with subtle reflections on the curved surfaces. Add structural details like support ribs, cables, and small panels along the walls, but keep the layout open enough for item placement and movement. Lighting should be soft and atmospheric, emphasizing the circular geometry and the central floor area.
