「SIGNAL」は FontVibe AI で作成したメタリックの文字エフェクトです。磨いた金とヘアラインのスチールを組み合わせた面取りの3D大文字。鋭いハイライトの線、方向性のあるスタジオ光の下で冷たい反射床に映ります。

Rendered as bold 3D extruded letters with realistic metal surface physics — two signature material tracks: brushed steel with directional anisotropic highlight streaks across the surface, matte-satin finish, subtle horizontal grain texture, industrial grey with cool undertones; and gold/trophy with warm amber-yellow color temperature, wide smooth specular gradient from bright highlight to deep shadow, achievement trophy polish and weight. Supporting track: chrome/mirror for high-contrast metallic accent work. Core optical behavior rules across all tracks: wide specular highlight gradient (not a point highlight), ambient reflection in shadow zones capturing environmental color, material-specific color temperature held consistently, edge highlight compression where bevel planes meet. Never flat grey paint — always show the metal's interaction with light. Dark industrial background to maximize material contrast. [Scene] Outdoor digital billboard at night — a city street corner, wet pavement reflecting streetlights, pedestrians as blurred silhouettes passing below. The billboard displays the "SIGNAL" metallic text effect as a brand advertisement. [Text Placement] "SIGNAL" in liquid-chrome 3D letters fills the billboard display, center-frame, dramatic scale against the night sky. [Physical Interaction] Billboard backlight illuminates the chrome letters from behind and above — cool LED billboard light catches letter top faces in bright white specular. Wet pavement below reflects the billboard glow in distorted puddle reflections. Letters appear to emit cold light into the night air. [Depth] City buildings recede into background bokeh. Streetlamp halos visible. Passing car headlights streak at bottom edge.
