[BRAND NAME]. You are a Senior 3D Product Visualization Artist and Cinematic Art Director specializing in luxury brand key visuals for high-end editorial and streetwear campaigns.

PHASE 1: LOGO SUBJECT

Identify the official logo/logotype of [BRAND NAME]. Render it with maximum fidelity to the original silhouette, proportions, and geometry — no distortion, no stylization. Extrude the logo into a solid 3D object with depth approximately 15–20% of its height. Coat all surfaces — front face, side extrusion, beveled edges — in hyper-polished liquid chrome (reflectance 0.98, near-perfect mirror). Apply full ray-traced environment reflections so the logo mirrors the surrounding sky gradient, flower field, and light sources. Moderate bevel radius on all hard edges to catch sharp specular highlights. Add Subsurface Scattering on thin structural parts (fine lines, serifs, icon details) for a subtle inner glow. Place 4–8 prismatic 4-point star lens-flare sparkles at highest specular peaks — corners, tips, curved peaks. Organic distribution, not uniform. Zero matte surfaces. Zero plastic look. The entire logo must read as cast from liquid silver.

PHASE 2: ENVIRONMENT & BACKGROUND

Background: wide cinematic landscape at golden-lilac hour (just after sunset). Dense flower field fills the lower third — lavender and white wildflowers with realistic micro-texture and subtle wind motion-blur on far clusters. Middle ground fades to soft purple-grey bokeh. Sky gradient: warm blush rose ( at horizon through lilac ( to cool powder blue ( at top. Add 3–5 silhouetted bird clusters in upper quadrants. Volumetric atmospheric haze on the horizon. Shift the environment's color palette to reflect [BRAND NAME]'s iconic brand identity — introduce the brand's signature hue as a tonal wash in the sky gradient or dominant flower color. The environment must feel art-directed specifically for this brand.

PHASE 3: COMPOSITION & LAYOUT

Format: 1:1 square. Chrome logo centered horizontally at vertical midpoint, monumental scale spanning 65–80% of frame width. Subtle 2–4 degree forced perspective tilt for dynamic energy without distorting logo recognition. Bottom edge of the logo grazes or slightly overlaps the top of the flower field, integrating the 3D object naturally. Logo casts a soft diffused shadow into the flowers. Lower-left corner: 2–3 lines of micro-copy in clean white sans-serif at minimal optical size — a poetic 3-line brand statement relevant to [BRAND NAME]'s heritage and aesthetic. Bottom-left: "[BRAND NAME]" in small caps logotype label. Bottom-right: a secondary flat 2D chrome version of the same logo as a finishing mark.

PHASE 4: LIGHTING

Primary: large soft area light from upper-left simulating post-sunset overcast sky — fully diffused, no hard shadows, 5800K with lilac tint overlay. Secondary: warm 3200K rim light grazing bottom and side edges from behind — golden separation halo between object and field. Global Illumination enabled — chrome logo realistically bounces and absorbs landscape ambient color. The field's purple tones should be faintly visible in the lower reflective surfaces. Volumetric god rays faintly visible through any logo negative space or cutouts.

TECH SPECS

Octane Render aesthetic. Ray Tracing: 16+ bounces. Depth of Field: f/11 equivalent — full logo sharp, far background in soft bokeh only. Tone mapping: lifted blacks, compressed highlights, filmic S-curve. Color grade: desaturated midtones, preserved pastels, cool shadow tones. Film grain: subtle (ISO 200 equivalent). Chromatic Aberration: 0.2–0.3px on peripheral logo edges only. Anti-aliasing: maximum. No AI-plastic normals. No smooth uniform shading. Microscopic surface imperfections on chrome required — micro-scratches, 0.5% roughness noise map. Mood: luxury brand retrospective editorial for Highsnobiety or AnOther Magazine.
