# Environment Controller
Starting from **realvirtual.io Version 6**, the EnvironmentController leverages Unity's **Universal Rendering Pipeline (URP)** to provide enhanced visual fidelity and customization options.
You can find the **EnvironmentController** in **Tools > realvirtual > Environments** as part of the **realvirtual Prefab** in your scene.
***
### Overview
The EnvironmentController provides three preset visual modes:
* **Default**: A balanced environment for general use.
* **Dark**: Suitable for low-light or nighttime scenarios.
* **White**: Ideal for bright, minimalistic environments.
The component allows adjustments to floor size, fade effects, and toggling advanced features with straightforward controls.

### Customizing the Environment
The recommended way to customize the Environment Controller is by **overwriting the values of the real irtual prefab** in your scene. This approach ensures that your changes are scene-specific while maintaining compatibility with the RealVirtual framework.
#### Prefab Structure
Each visual setup is organized as a **sub-gameobject** within the prefab. These sub-gameobjects are activated dynamically based on the current **visual mode setting**. The three primary modes included are:
* **Dark Mode**
* **Default Mode**
* **White Mode**
Each mode contains the following key components:
**1. Sun**
* Represents the primary directional light source for the scene.
* Customize the **intensity, color, and angle** of the light for desired effects.
**2. Floor**
* Defines the material and rendering properties for the ground plane.
* Update the floor's texture, material properties, or color to match your scene's aesthetics.
**3. Sky**
* Manages the skybox or atmospheric effects.
* Customize the sky material to change the overall ambiance of the environment.
#### Effects and Post-Processing
Under the **Effects** section of each sub-gameobject, you will find settings related to **post-processing**. These can be tailored to adjust the mood, tone, and visual clarity of the scene. Common properties include:
* **Bloom**: Adjust intensity and threshold for glow effects.
* **Color Grading**: Modify contrast, saturation, and color tones.
* **Ambient Occlusion**: Enhance shadow details for better depth perception.
* **Motion Blur**: Add a sense of motion for dynamic scenes.
* **Vignette**: Focus viewer attention by darkening edges.
