Drag the CameraArrayManager Actor into your scene. All camera array controls will be managed through this Actor's Details panel.
When selecting the CameraArrayManager in the scene, you will see the following parameters in the Details panel.
| Parameter Group | Setting | Description | Notes / Range |
|---|---|---|---|
| Camera Array Setup | Camera Count | Defines the total number of cameras to create in the array. | 1 - 99 |
| Total Y-Distance | The total distance (in meters) over which all cameras are distributed along their local Y-axis. | Example: 10.0 | |
| Start Position | The world space coordinates (X, Y, Z) of the first camera in the array. | Vector (X,Y,Z) | |
| Uniform Rotation | Rotation angles (Roll, Pitch, Yaw) applied to all cameras. Only effective when LookAtTarget is disabled. | Rotator (R,P,Y) | |
| Camera Properties | Camera FOV | The Field of View angle for all cameras in the array. | 1° - 170° |
| Render Output | Output Width/Height | The resolution (in pixels) of the rendered output images. | Example: 1920x1080 |
| Format | The output file format for rendered images. | PNG, JPEG, BMP, TGA, EXR | |
| Output Path | The folder path where images are saved, relative to the project's Saved/ directory. | Default: RenderOutput | |
| Overwrite Existing | If checked, rendering will overwrite existing files with the same name. | Boolean | |
| Camera Prefix | The base name for output files. The system automatically appends a numeric suffix (e.g., MyRender_01.png). | Example: MyRender_ | |
| Look At Target | Enable LookAtTarget | If checked, all cameras automatically rotate to face the specified target Actor. | Boolean |
| Scene Target | An Actor reference. Drag an Actor from the World Outliner here to set it as the focal point. | Actor Reference | |

At the bottom of the Details panel, you will find a series of action buttons for executing core functions.
- Create or Update Cameras: Creates a new camera array based on current parameter settings, or updates an existing array.
- Clear Cameras: Deletes all cameras created by this manager.
- Select First/Last Camera: Quickly selects the first or last camera in the array in the editor for inspection.
- Render First/Last Camera: Renders and tests the view from the first or last camera in the array individually.
- Batch Render High-Res Screenshots: Initiates the batch rendering process, capturing a high-resolution screenshot from every camera in the array.
- Open Output Folder: Opens the folder where rendered images are saved directly in your operating system.
Important Note: Requirements for Path Tracing Rendering
To achieve true Path Tracing render results, you must follow these steps:
- Set Viewport Mode: In your main editor viewport, change the "View Mode" from "Lit" to "Path Tracing". This plugin's render results strictly depend on the currently active viewport configuration.
- Specify Post Process Volume: Drag a Post Process Volume from your scene into the Post Process Ref slot of the CameraArrayManager.
- Set SPP Sample Count: In your Post Process Volume settings, locate the "Path Tracing" category and set "Samples Per Pixel" to your desired quality level. The plugin uses this value to determine render duration per frame. Higher SPP values produce cleaner images but increase render time accordingly.
- Supported Unreal Engine Versions: 5.3+
- Supported Platforms: Windows, macOS
- Supported Image Formats: PNG (8-bit), JPEG (8-bit), BMP (8-bit), TGA (8-bit), EXR (16-bit Float)
- Keep Editor Active During Rendering: For the batch rendering process to work properly, Unreal Editor must be the active window on your computer. Switching to other applications may interrupt the screenshot process.
- Maintain Stable Editor State: For reliable render results, avoid modifying the scene, adjusting parameters, or interacting with other editor UI elements during batch rendering. The plugin includes safeguards against most accidental modifications, but a stable environment is key to successful rendering.
- Disk Space Management: Rendering large quantities of high-resolution images consumes considerable disk space. Ensure your target output directory has sufficient available space before starting large batch renders.
- Performance Considerations: Batch rendering is resource-intensive. For optimal performance, it is recommended to close other GPU-intensive applications during rendering.
