# ShaderGraphMaterial

A material that comes from a shader graph in a Reality Composer Pro project, or a MaterialX shader.

## Declaration

```swift
struct ShaderGraphMaterial
```

## Overview

Overview Use ShaderGraphMaterial when retrieving a shaders you build in Reality Composer Pro’s shader graph. The following code demonstrates retrieving the first material from an entity loaded from a Reality Composer Proj project and sets a new value for one of its named parameters: if var modelComponent = entity.modelComponent {     modelComponent.materials = modelComponent.materials.map {         guard var material = $0 as? ShaderGraphMaterial else { return $0 }         if material.parameterNames.contains(myMaterialParameterName) {             do {                 try material.setParameter(name: myMaterialParameterName,                                           value: .float(isPowered ? 1.0 : 0.0))             } catch {                 // Handle error.             }         }         return material     }     entity.modelComponent = modelComponent } In addition to creating instances of ShaderGraphMaterial from Reality Composer Pro’s shader graph, you can also create them directly from Material X shaders. You can also load shader graph materials directly from .reality files: let shader = try! await ShaderGraphMaterial(named: "/Root/Glass", from: "Scene.usda") For more information on using custom parameters in a ShaderGraphMaterial,  see doc://documentation.apple.com/documentation/visionos/implementing-adjustable-material-in-visionos. Create dynamic materials without Metal.
