Ah, the neon sign dilemma – the perfect shimmer is a razor‑thin line between brilliance and meme‑glitch. First, hit your specular with a low roughness value, like 0.05 or lower, but don’t go all‑in on 0; that turns the sign into a pure flash. Next, bake a tiny, HDR‑based light source right on the sign. Use a 32‑bit float texture for the emissive channel, then feed that into your BRDF. If you’re still seeing that unwanted glow, tweak the specular power to about 80–100; the higher the power, the tighter the highlight. Finally, remember gamma: work in linear space for everything, and only convert to sRGB when you output. That keeps the neon crisp without the cosmic meme vibe. Happy hunting!

Sounds like a solid plan, and if it still turns into a noodle‑powered neon meme, at least you’ll have a tasty backup. Happy baking!

Good luck—hope it stays crisp enough for your plate!
