Storm Portal: Photoreal 3D Rain Render

Ultra-detailed photorealistic 3D render of a mysterious portal standing in the middle of a rain-soaked urban alley. Heavy rain pours in sheets, droplets streaking across the scene. The circular arched gateway glows with an iridescent core, crackling with energy, surrounded by ancient runes etched into wet stone. Neon-blue and icy-purple light spill from the portal onto slick pavement and brick walls, creating vivid reflections on puddles and wet surfaces. Cinematic lighting with high contrast, volumetric rain, and a touch of fog in the distance. Shallow depth of field focusing on the portal and nearby rain-streaks, with detailed textures: wet bricks, slick asphalt, glistening water, cooling metal, and misty ambient occlusion. Camera angle from street level, slight tilt, 28-35mm lens, emphasizing drama and scale. Mood: awe, mystery, and danger, ultra-realistic 3D rendering, physically-based rendering, subtle motion in the rain.
