AI Billboard 3D: Outdoors Gigantes na Fachada

// WORKFLOW: 3D ANAMORPHIC FAÇADE BILLBOARD
// STEP 1 — ChatGPT (Generate Empty Building Scene)
Generate an ultra-realistic commercial street scene featuring a tall narrow blank building wall specifically designed for a large vertical advertisement installation.
Requirements: Modern downtown city with premium architecture (New York / Tokyo style). Camera angle: street-level looking slightly upward (24–35mm lens). One building must have a completely blank, clean concrete wall covering around 5–6 floors. No billboard. No banner. No advertisements. No logos. Leave the wall perfectly empty for later compositing. Cinematic lighting. Vertical composition (9:16).

// STEP 2 — ChatGPT (Composite Product Artwork onto Building)
Using the first image as background and uploaded artwork as advertisement, create a realistic hanging wall banner. Replace blank wall with advertisement. Scale naturally to fit. The banner appears as a premium flexible vinyl sheet attached from the top, naturally curling outward due to gravity with realistic folds and accurate contact shadows.

// STEP 3 — Google Omni / Seedance (Animate)
Animate this still image into a realistic cinematic advertisement installation. Camera remains mostly static with a slow cinematic push-in. The large hanging banner behaves like a real flexible vinyl sheet. A gentle breeze causes the bottom of the banner to slowly roll outward, creating smooth wave-like motion across the fabric. Style: ultra-photorealistic, premium commercial VFX, 24 fps, natural physics, 4K quality, vertical 9:16.
