Sketch to Render

Ultra-realistic architectural rendering of a U-shaped staircase with four diagonal landings and three straight stair flights, preserving 100% of the original geometry, dimensions, proportions, and composition from the provided SketchUp screenshot.

Materials:

* Stair risers clad in premium white sintered stone.
* Stair treads finished with luxury black sintered stone featuring subtle lightning vein patterns.
* Clean seamless joints, precise stone fabrication details.
* High-end craftsmanship, sharp edges, realistic stone textures and reflections.

Rendering Requirements:

* Maintain the exact staircase shape and structure from the SketchUp model.
* Do not alter the design, layout, dimensions, or camera perspective.
* Photorealistic materials with physically accurate PBR textures.
* Natural color balance and realistic contrast.
* Soft daylight illumination entering from surrounding space.
* Accurate global illumination, ambient occlusion, ray-traced reflections, and realistic shadows.
* Architectural visualization quality comparable to Corona Renderer, V-Ray 7, or high-end Lumion renderings.
* Ultra-detailed stone surfaces, realistic micro-textures, premium luxury appearance.
* Sharp focus, HDR lighting, cinematic realism.
* Professional interior architectural photography style.
* 8K resolution, ultra high detail, hyper realistic, masterpiece quality.

Negative Prompt:
Do not change the staircase geometry, do not redesign, no additional decorations, no extra handrails, no distorted proportions, no cartoon style, no CGI look, no overexposed lighting, no blurry textures, no unrealistic materials, no low resolution, no artifacts.
"Strictly preserve the original SketchUp model geometry and camera angle. Use the SketchUp screenshot only as a base for photorealistic rendering. No redesign, no geometry modification, no composition changes."
