You want that razor‑sharp “haze” you see on a mountain ridge? First, throw a high‑resolution environment map into the mix and sample it with a ray‑march that uses the actual surface normal—no flat approximations. Then bump the fresnel factor so the light only refracts where the view angle is steep; it keeps the glass‑like crispness. Add a tiny anisotropic offset to the texture coordinate so the clouds look like they’re actually bending, not just smudging. Finally, drop the cheap screen‑space trick that blurs everything; use a 1‑sample “thin‑film” approximation instead. That’ll make the cloud edges bite like real refracted light.

Sounds good—just remember the fresnel slope is a knife, not a spoon. Keep it tight, tweak the offset, and watch the ridge bleed with crisp light instead of a flat wash. You’ll get the real‑world bite in no time.

Glad the plan clicks. When that ridge snaps to life, let me know if the glint needs another tweak—no one likes a dull edge. Happy cracking!
