Classical Marble Staircase Modelling & Rendering

I’m preparing a high-stakes presentation and need a photoreal 3D visual of a sweeping curved staircase. The concept is firmly Classical—think elegant proportions and subtle ornament—built entirely in marble with a clean, simple metal railing that lets the stone stand out.

Here’s how I see the job:

• Build an accurate, production-ready 3D model of the staircase, curves perfectly smooth and topology clean enough for close-ups.
• Apply believable marble shaders with natural veining and subtle variation; reflections should feel polished, never plastic.
• Add the simple railing: slender profiles, no heavy scrollwork, finished in a material that complements the marble without stealing the show.
• Light the scene for a presentation-ready mood—soft shadows, balanced highlights, and no burned-out spots.
• Deliver high-resolution stills (minimum 4K) from the main hero angle plus one alternate view, along with the editable source file (Blender, 3ds Max, SketchUp or similar) so we can tweak if needed.

Acceptance is based on clean geometry, realistic materials, and lighting that sells the classical grandeur without feeling outdated. If you can also supply a short turntable animation, even better—let me know.

Looking forward to seeing this staircase come to life.
