# BlendShapeWeightsComponent

A component that provides access to the current weights associated with all blend shape meshes on an entity.

## Declaration

```swift
struct BlendShapeWeightsComponent
```

## Overview

Overview You can access the weights associated with an entity’s blend shapes by using the weightSet variable after an initialized BlendShapeWeightsComponent is added to an entity. let blendShapeWeightsComponent = BlendShapeWeightsComponent(     weightsMapping: weightsMapping) entity.components.set(blendShapeWeightsComponent) let weightValues = BlendShapeWeights([0.3, 0.8]) entity.components[BlendShapeWeightsComponent.self]!.weightSets[0].weights =     weightValues
