# Main Camera
|
||
|
|
|
||
|
|
Menu Path : **Operator > BuiltIn > Main Camera**
|
||
|
|
|
||
|
|
The Main Camera Operator returns available information from the current main camera. It uses an equivalent behavior to [Camera.main](https://docs.unity3d.com/ScriptReference/Camera-main.html) and an integration into the active Scriptable Render Pipeline for depth buffer and color buffer access.
|
||
|
|
|
||
|
|
## Operator properties
|
||
|
|
|
||
|
|
| **Output** | **Type** | **Description** |
|
||
|
|
| ---------- | ------------------------ | ---------------------------------- |
|
||
|
|
| **o** | [Camera](Type-Camera.md) | Information about the main camera. |
|
||
|
|
|
||
|
|
## Remarks
|
||
|
|
|
||
|
|
If the main camera is unavailable, which can occur if:
|
||
|
|
|
||
|
|
- If there is no camera GameObject tagged as **MainCamera** within the scene.
|
||
|
|
- You manually trigger [Simulate](https://docs.unity3d.com/Documentation/ScriptReference/VFX.VisualEffect.Simulate.html)
|
||
|
|
- It is during the prewarm update of the Visual Effect component.
|
||
|
|
|
||
|
|
If this is the case, the [Camera](Type-Camera.md) this Operator returns has the following default values:
|
||
|
|
|
||
|
|
| **Property** | **Default value** |
|
||
|
|
| ------------------ | ----------------------------------------------------------- |
|
||
|
|
| **Transform** | Transform identity : position zero, scale one, no rotation. |
|
||
|
|
| **fieldOfView** | 60.0 |
|
||
|
|
| **nearPlane** | 0.3 |
|
||
|
|
| **farPlane** | 1000 |
|
||
|
|
| **aspectRatio** | 1.0 |
|
||
|
|
| **pixelDimension** | (1920, 1080) |
|
||
|
|
| **depthBuffer** | Default texture2D array (gray texture) |
|
||
|
|
| **colorBuffer** | Default texture2D array (gray texture) |
|
||
|
|
|
||
|
|
The **depthBuffer** and **colorBuffer** textures are only available in a Scriptable Render Pipeline that implements [VFXManager.SetCameraBuffer](https://docs.unity3d.com/Documentation/ScriptReference/VFX.VFXManager.SetCameraBuffer.html). HDRP officially supports this integration.
