# 3D preview tab reference

> Explore the properties and settings available in the 3D preview to inspect assets, control camera behavior, customize grid and wireframe displays, and manage viewing tools.

In the **Project Assets** interface, select an asset to preview it. By default, it opens in the **Thumbnail** tab, which is a 2D viewer. Select the **3D preview** tab to inspect your asset in a 3D viewer.

> **Note:**
>
> The 3D preview provides an approximation of your asset. Unity Pipeline converts assets into a format optimized for web preview. Custom shaders, materials, lighting, and other rendering effects might not appear exactly as they do in the Unity Editor.

## 3D preview toolbar

### Material channels

Use material channels to inspect a 3D asset without changing the original asset’s materials. Material channels are baked into the model as a single texture. This enables efficient rendering and ensures a consistent appearance across environments.

You can inspect the following material channels:
