“F M” is a Fire Smoke text effect 使用 FontVibe AI 创作的文字效果. 熊熊燃烧的火焰与烟雾特效，戏剧化的热浪和余烬光芒.

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. Two monumental letterforms reading “F M” emerge from a furnace-dark charcoal haze, their surfaces consumed by real combustion: incandescent white-yellow cores visible through cracked glowing edges, transitioning to molten amber, saturated orange, and deep red at the outer contours. Tall turbulent flame tongues tear upward from every exposed edge with irregular fluid motion, transparent blue-grey tips dissolving into dense rolling charcoal smoke. Heavy smoke columns coil and billow above the letters, faintly translucent where they catch the firelight. A violent heat source beneath casts a concentrated amber-orange underglow across the scene, with sharp upward rim illumination, heat-distortion ripples, and ray-traced volumetric haze. Sparse ember sparks rise in varied sizes and trajectories, some blurred by shallow depth of field. The surrounding background remains deep charcoal-black rather than flat black, carrying a barely visible volcanic glow and drifting ash texture. The text dominates with broad negative space around its burning silhouette; no additional words, symbols, or decorative typography. Cinematic fire photography, high contrast, physically based flame simulation, detailed soot, ember particles, smoke turbulence, 8k.
