“Diaz Coach”是使用 FontVibe AI 创作的3D 立体粗体文字效果。厚重的方块大写字母带深度挤出，每个字母一种亮面糖果色，顶光让高光滚过圆润边角，彩色倒影落在地面上。

Create a finished, horizontal 3:2 locker-room nameplate product image. Show one sturdy rectangular nameplate as the central physical object, front-facing with a slight low camera angle. Use a plain, nearly black studio floor and background; keep the environment minimal so the lettering carries the visual impact. The plaque is a simple dark graphite metal plate with two discreet mounting bolts and clean squared edges. Render exactly these words, spelled and cased as shown: “Coach” above “Diaz”. Make “Diaz” the dominant headline, large and centered across the plaque; set “Coach” smaller as a centered label immediately above it. Keep both lines highly legible and fully visible. Build every letter as a massive, chunky 3D block with uniform extrusion approximately 55% of its letter height, hard sharp face-to-side edges and no bevel. Finish each front face in ultra-glossy hard-candy lacquer, with natural specular highlights graduating into saturated color. Use a different vivid hue family on every adjacent letter, alternating cherry red, electric blue, sunshine yellow, lime green and hot orange across the lettering; use darker shades of each hue on the extrusion sides. Strong directional key light from the upper left; crisp, long cast shadows fall consistently at 45 degrees, with shadow depth around 45% of the letter height. Add a restrained reflection beneath the plaque on the dark studio floor. Professional 3D motion-graphics product rendering, precise geometry, clean edges, high contrast. No other words, logos, props or decorative clutter.
