<lora:flux_realism_lora:1>, A hyper- realistic Unreal Engine 5 scene of a fragmented, floating techno- fortress suspended above a dark, swirling abyss. The fortress features photorealistic metal structures and intricate machinery, creating a cold, sterile environment. Utilize Nanite geometry for ultra- detailed surfaces composed of interlocking metal plates, cables, and towering spires. Implement Lumen global illumination to showcase glowing circuits and energy conduits running through every surface. Apply high- quality material instances for a mechanical, precise atmosphere, with subtle audio cues of machinery hum and electrical sparks. Use Niagara particle systems for the disintegrating edges of the fortress, creating a cloud of digital particles fading into the darkness below. In the foreground, render a close- up view of Ultron's back using high- poly character models and advanced shaders. Capture the sleek, menacing design of his metallic body with a cold, silvery sheen. Utilize tessellation and displacement mapping for intricate mechanical details on his frame, seamlessly blending humanoid structure with advanced technology. Implement ray- traced reflections to showcase sharp angles and glowing red lines along his body contours. Position his angular head slightly tilted, suggesting calculation or surveillance. Model broad shoulders and powerful limbs with meticulous attention to detail. Animate one raised hand with fingers slightly splayed, emitting a faint red glow using volumetric lighting to hint at his immense power and control over the surrounding technology. Create a dark void sky using volumetric fog and dynamic lighting, occasionally pierced by ray- traced digital lightning and the soft glow of distant energy sources. Utilize screen space reflections to cast this light onto Ultron's metallic surface, generating long, sharp shadows that emphasize his cold, inhuman nature. Implement high- quality ambient occlusion and contact shadows to enhance depth and complexity, highlighting the intricate details of Ultron's design and the advanced technology defining his existence. Employ cinematic post- processing effects to achieve a cold, calculated power and relentless precision, capturing Ultron's essence within this surreal, technologically advanced landscape. Utilize color grading and bloom effects to emphasize glowing red lines and deep shadows, underscoring the stark, unforgiving nature of the environment and the figure. Frame the composition to focus on the fragmented, floating fortress, with Ultron's detailed depiction adding a sense of calculated menace and unstoppable force against the surreal, high- tech backdrop. Optimize the scene for high- end hardware to maintain 60+ FPS at 4K resolution with ray tracing enabled
