# ComputeGraphOutputComponent

A transient component that identifies the compute graph output associated with an entity.

```
struct ComputeGraphOutputComponent
```

## Overview

The system attaches this component to child entities that represent individual
graph outputs. Use `outputID` to correlate the entity with a specific output
inside the owning entity’s running simulation.

## Topics

### Instance Properties

[`var outputID: ComputeNodeGraph.NodeID`](/documentation/RealityKit/ComputeGraphOutputComponent/outputID)
