## Required Components

**1. Tooltip Controller (Scene-Level)**

You must add the Tooltip Controller to your scene. This controller handles the positioning and display of all tooltips.

> 📦 **Prefab**:\
> `Assets/realvirtual/Professional/SceneSelection/TooltipController.prefab`

Drag and drop this prefab into your scene to enable the tooltip system.

**2. RuntimeTooltip Script (Object-Level)**

Attach the `RuntimeTooltip` script to any GameObject you want to annotate with a tooltip.

**Steps:**

1. Select the target GameObject (e.g., a cabinet).
2. Add the component: `Runtime Tooltip (Script)`
3. Enter your tooltip text in the **Text** field using TextMeshPro for formatting if needed.

**Example:**

```html
<b><color=#FFD700>Cabinet</color></b>\nContains control electronics and power supply
```
