Iris/Oculus For Simple Clouds

☁️ **Oculus for Simple Clouds — Progress Update**

## 🧠 Summary
- Clouds now react properly to sunrise and sunset 🌅
- Lighting is now handled directly in the cloud shaders (no more fake tint)
- Stable baseline restored after removing broken experiments
- Works even without shaderpacks

---

## 🔥 What’s Working
- 🌅 Sunrise / sunset coloring → **YESSS**
- 🧱 Alex’s Caves → **YEEESSS**
- ⚙️ Immersive Engineering → **YEEESSS**

## 🎨 Current State
- Transparent clouds → looking great ✅
- Distant clouds → already good, untouched ✅
- Opaque clouds → still a bit too gray (being improved)

---

## ❌ Not Working Yet

---

## 🚧 In Progress
- Improve warm lighting on opaque clouds
- Keep natural variation (no flat colors)
- Match the look of transparent clouds

We’re VERY close now 👀
Just need that final touch of sunlight on the main cloud body.
