# SetRayTracingTextureParam

> Adds a command to set a texture parameter on a RayTracingShader.

## Definition

* **Type:** Method
* **Namespace:** [UnityEngine.Rendering](/engine/6000.6/script-reference/unityengine/rendering.md)
* **Assembly:** UnityEngine.CoreModule

## SetRayTracingTextureParam(RayTracingShader, string, RenderTargetIdentifier)

Adds a command to set a texture parameter on a [RayTracingShader](/engine/6000.6/script-reference/unityengine/rendering/raytracingshader.md).

```csharp
public void SetRayTracingTextureParam(RayTracingShader rayTracingShader, string name, RenderTargetIdentifier rt)
```

### Parameters

**** (\[RayTracingShader]\(/engine/6000.6/script-reference/unityengine/rendering/raytracingshader)): RayTracingShader to set parameter for.**** (\[string]\(https\://learn.microsoft.com/dotnet/api/system.string)): Name of the texture variable in shader code.**** (\[RenderTargetIdentifier]\(/engine/6000.6/script-reference/unityengine/rendering/rendertargetidentifier)): Texture value or identifier to set, see [RenderTargetIdentifier](/engine/6000.6/script-reference/unityengine/rendering/rendertargetidentifier.md).

### Remarks

Only shaders defined in the .raytrace file can access the texture you designate as the argument for this method. To make this texture accessible to all ray tracing shader types (closest hit, any hit, or miss, for example), call the [CommandBuffer.SetGlobalTexture](/engine/6000.6/script-reference/unityengine/rendering/commandbuffer/setglobaltexture.md) method instead.

## SetRayTracingTextureParam(RayTracingShader, int, RenderTargetIdentifier)

Adds a command to set a texture parameter on a [RayTracingShader](/engine/6000.6/script-reference/unityengine/rendering/raytracingshader.md).

```csharp
public void SetRayTracingTextureParam(RayTracingShader rayTracingShader, int nameID, RenderTargetIdentifier rt)
```

### Parameters

**** (\[RayTracingShader]\(/engine/6000.6/script-reference/unityengine/rendering/raytracingshader)): RayTracingShader to set parameter for.**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): The ID of the property name for the texture in shader code. Use [Shader.PropertyToID](/engine/6000.6/script-reference/unityengine/shader/propertytoid.md) to get this ID.**** (\[RenderTargetIdentifier]\(/engine/6000.6/script-reference/unityengine/rendering/rendertargetidentifier)): Texture value or identifier to set, see [RenderTargetIdentifier](/engine/6000.6/script-reference/unityengine/rendering/rendertargetidentifier.md).
