Create a hyper-realistic Unreal Engine asset of a massive neon sign that simply reads 'VEGAS' in bold retro lettering. The sign should glow with vintage charm — red and gold neon tubes cracked and flickering, mounted on a rusted metal frame weathered by decades of desert heat. Thick, glowing ooze drips from each letter, viscous and semi-translucent, glowing toxic green and violet as it clings to the neon edges. The slime should pulse faintly with light, pooling below the letters and reflecting their glow. Add subtle smoke, particle drips, and wet reflective surfaces to enhance cinematic realism, giving the scene a haunting yet captivating Vegas decay vibe
