「ATOMKRAFT NEJ TACK」は FontVibe AI で作成した炎と煙の文字エフェクトです。燃え盛る炎と煙のエフェクト、劇的な熱波と燃え残りの輝きを表現します。

Real combustion physics: white-yellow inner core transitioning through orange and deep red to wispy blue-grey outer tips. Turbulent flame tongues surge upward with natural random motion. Dense dark smoke billows in heavy rolling columns, curling upward — charcoal and near-black with faint translucency at edges. Firelight self-illuminates from below with warm amber-orange cast. Dramatic upward rim from intense heat source underneath. Background: deep charcoal haze with faint ember glow — not pure black. Cinematic fire photography quality. 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 flame-and-smoke material, the combustion glow and the cast light. FALLBACK MATERIAL: if the font carries no material of its own, render the letters ablaze — a white-yellow core through orange to deep red flame tongues with dark rolling smoke and warm self-illumination from below. COLOR PRIORITY: keep the font's own colors if specified; otherwise the natural fire spectrum of amber, orange and deep red. Deep charcoal haze environment — near-black background with faint ember glow pulsing from below, scattered amber spark particles drifting upward through the frame, heat distortion rippling through the air above and around the letterforms. 'ATOMKRAFT / NEJ TACK' rendered as two stacked lines of fire-engulfed letters — 'ATOMKRAFT' above, larger and dominant, 'NEJ TACK' below, slightly smaller — each character built from a white-yellow inner combustion core transitioning outward through vivid orange to deep red flame tongues at the edges. Tall turbulent flame columns surge upward from every letterform, individual flame tips forking and splitting with natural random motion. Dense dark smoke billows in heavy rolling columns above the letters — charcoal and near-black with faint translucency at curling edges. Warm amber-orange self-illumination radiates from the fire source beneath, casting a rich upward rim light across the entire composition. Firelight warms the surrounding haze with a deep ember cast. Microscopic heat shimmer distorts the air in bands above the letters — physical combustion realism. Cinematic fire photography quality, high-contrast chiaroscuro, dramatic upward key light from intense heat source, 8k render resolution, photorealistic combustion physics.
