# blendMode

The blending mode for compositing particle images into the rendered scene.

```
var blendMode: SCNParticleBlendMode { get set }
```

## Discussion

Together with the [`sortingMode`](/documentation/SceneKit/SCNParticleSystem/sortingMode) property, blend modes affect the appearance of overlapping particle images when rendered.

For possible blend modes, see [`SCNParticleBlendMode`](/documentation/SceneKit/SCNParticleBlendMode). The default value is [`SCNParticleBlendMode.additive`](/documentation/SceneKit/SCNParticleBlendMode/additive).
