Submarine Inside a Time Machine — 3D Render

Ultra-detailed, photorealistic 3D render of a modern submarine being enveloped by a gigantic time machine chamber. The submarine features a brushed steel hull with subtle weathering, a prominent conning tower, fins, and portholes reflecting a glow. It sits on magnetic rails inside a vast cylindrical chamber filled with volumetric fog. Surrounding it are ornate brass gears, copper piping, riveted panels, and glowing amber runes in a steampunk-futuristic aesthetic. A luminous time portal dominates the far end: a swirling vortex of electric blue and violet energy with orbiting numeric glyphs. Subtle rain-like droplets cling to surfaces, and soft reflections shimmer on polished metal and glass. The scene uses PBR materials and cinematic lighting: cyan rim light, warm tungsten accents, and a strong backlight from the portal. Camera: three-quarter view from above, focusing on the submarine's bow and the rotating time-gate, with depth of field that blurs the chamber walls behind. Mood: awe-inspiring, exploratory, scientifically plausible within a sci-fi adventure.
