「갑자기」は FontVibe AI で作成した3D 太字の文字エフェクトです。深く押し出された極太のブロック体大文字。一文字ずつ艶のあるキャンディカラーで、上からの光がハイライトを丸い角に走らせ、床に色の映り込みが広がります。

Massive chunky 3D block letters with heavyweight extruded presence — thick uniform extrusion depth of 50-60% of letter height. Front face finished in ultra-glossy lacquer, catching directional key light with natural specular reflections that graduate from bright highlight to deep saturated color — the surface quality of hard candy coating or high-gloss toy paint. Side extrusion planes in a noticeably darker shade of the same hue, creating crisp face-to-depth contrast that reads immediately as three-dimensional volume. Adjacent letters each carry a different vivid saturated color, maximizing chromatic contrast across the word — no two adjacent letters share the same hue family. Hard sharp corner edges where face meets extrusion, no beveling. Long dramatic cast shadows at consistent 45-degree angle, shadow depth approximately 40-50% of letter height. Strong directional key light from upper left. Bold, high-contrast, maximum visual impact. LETTERFORM PRIORITY: when the chosen font carries its own treatment, that font's letterform shapes take priority and own the letters; this style governs the glossy 3D extrusion, the directional lighting and the multi-color scheme. FALLBACK MATERIAL: if the font carries no material of its own, render the letters as thick glossy extruded 3D blocks with hard candy-lacquer faces and darker extrusion sides. COLOR PRIORITY: if the font specifies its own colors, keep them; otherwise give each adjacent letter a different vivid saturated hue. Create a striking Korean title image built around the exact text “갑자기,” arranged on one line and centered as the unmistakable focal point. Let the compact word occupy most of the canvas width, with generous breathing room around it so every character remains clear and fully visible. Treat each character as an independent, vividly colored sculptural object, with neighboring characters in contrasting hue families. Set the composition against a minimal, seamless near-black studio floor and backdrop; keep the environment quiet so the lettering carries all the drama. A strong upper-left spotlight sends crisp reflections across the glossy surfaces and throws long, sharply defined diagonal shadows toward the lower right. Add restrained reflections directly beneath the characters on the polished floor, fading quickly into darkness. Use a slightly low, frontal viewpoint to give the word commanding physical presence while keeping the Korean text easy to read. The finished image should feel bold, playful, and premium, with clean edges, rich saturated color, dramatic depth, and no other visible words, symbols, or decorative elements.
