How to add a world light in UE5.5
In Unreal Engine 5.5, adding a **world light** (commonly referred to as a **Directional Light** for simulating sunlight) is straightforward. Here’s a step-by-step guide to adding and configuring one properly:

—

### ✅ STEP-BY-STEP: Add a World Light (Directional Light)

#### 1. **Open Your Level**
– Launch your UE5.5 project and open the level where you want to add the world light.

#### 2. **Add a Directional Light**
– Go to the **Place Actors** panel (usually on the left side).
– Under **Lights**, drag **Directional Light** into your scene.
– Alternatively, use the menu:
`Toolbar → Window → Place Actors → Lights → Directional Light`.

#### 3. **Position & Rotate**
– The **position** doesn’t matter much—it affects shadows minimally.
– The **rotation** determines the angle of the sunlight:
– Rotate along the **pitch** to simulate time of day.
– Rotate along **yaw** to change the sun’s direction.

#### 4. **Enable Atmospheric Lighting (Optional but Recommended)**
– In the **Details** panel for the Directional Light:
– Enable **Atmosphere / Fog Sun Light**.
– This allows it to interact with the **Sky Atmosphere**, **Volumetric Clouds**, and **Exponential Height Fog**.

#### 5. **Set as Movable (Optional, for Dynamic Lighting)**
– If you want **real-time lighting** (for dynamic day/night), change **Mobility** to **Movable**.
– Static: Baked lighting.
– Stationary: Mixed.
– Movable: Fully dynamic.

### 🌤 Bonus: Add Sky Atmosphere + Sun

For a full outdoor lighting setup:

#### 1. **Add Sky Atmosphere**
– From **Place Actors**, add a **Sky Atmosphere** to your scene.

#### 2. **Add Volumetric Clouds** *(optional for realism)*
– Place a **Volumetric Cloud** actor.

#### 3. **Add Exponential Height Fog**
– This creates the hazy atmosphere near the ground.

#### 4. **Add Sky Light**
– Place a **Sky Light** (set to Movable or Stationary) to capture ambient light.

### 🔄 Link Sun to Sky Atmosphere (If Not Automatic)

If your sky doesn’t update with sun rotation:

1. Select **Directional Light**.
2. In the **Details** panel, check **Use Sky Atmosphere**.
3. Also check **Affects World** and **Cast Shadows**.

how to move the viewport to another monitor?
To move the **Viewport** to another monitor in **Unreal Engine 5.5**, you can “tear off” the viewport tab and drag it to your second screen. Here’s how:

—

### 🖥️ STEP-BY-STEP: Move Viewport to Another Monitor

#### 1. **Undock the Viewport Tab**
– Click and drag the **”Viewport” tab** (top of the viewport panel).
– When you drag it out of the main editor window, it becomes a **floating window**.

#### 2. **Move to Second Monitor**
– Simply drag the floating **Viewport window** to your second monitor.

#### 3. **Maximize or Resize**
– You can maximize the window or manually resize it to fit your second screen.

#### 4. *(Optional)* **Save Layout**
– Go to `Window → Save Layout` so UE5 remembers your setup next time.

### 🔄 Reset Layout (If Needed)
If things get messy or the viewport doesn’t reappear:

– Go to:
`Window → Load Layout → Default Editor Layout`
or
`Window → Reset Layout`.
