New update time! This one is quite smaller than previous updates but delivers some nice improvements to the shader overall!

---Lighting---

• Greatly improved lighting
  • Added Lambertian diffuse lighting. Lighting is now properly physically based within a BRDF
• Adjusted the skylight intensity at most times of day

---Atmosphere---

• Improved the blending of fog between terrain and sky
• Improved sun fog visibility
• Added cave fog transitions
  • Fog now fades out when entering a cave and a new fog will slowly roll in based on the current mood
• Improved godrays
  • They now have a small cutoff range, making them look and feel less awkward
• Adjusted the MIE Scattering of the sky to be less intense

---Materials---

• Improved the handling of metals
• Fixed an oversight with emissives that resulted in them being less intense than intended and clipping to pure white
