# SetRayTracingVectorArrayParam

> Adds a command to set a vector array parameter on a RayTracingShader.

## Definition

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

## SetRayTracingVectorArrayParam(RayTracingShader, string, Vector4\[])

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

```csharp
public void SetRayTracingVectorArrayParam(RayTracingShader rayTracingShader, string name, params Vector4[] values)
```

### Parameters

**** (\[RayTracingShader]\(/engine/6000.6/script-reference/unityengine/rendering/raytracingshader)): RayTracingShader to set parameter for.**** (\[string]\(https\://learn.microsoft.com/dotnet/api/system.string)): Property name.**** (\[Vector4\[]]\(/engine/6000.6/script-reference/unityengine/vector4)): Value to set.

### Remarks

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

## SetRayTracingVectorArrayParam(RayTracingShader, int, Vector4\[])

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

```csharp
public void SetRayTracingVectorArrayParam(RayTracingShader rayTracingShader, int nameID, params Vector4[] values)
```

### Parameters

**** (\[RayTracingShader]\(/engine/6000.6/script-reference/unityengine/rendering/raytracingshader)): RayTracingShader to set parameter for.**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): Property name ID. Use [Shader.PropertyToID](/engine/6000.6/script-reference/unityengine/shader/propertytoid.md) to get this ID.**** (\[Vector4\[]]\(/engine/6000.6/script-reference/unityengine/vector4)): Value to set.

### Remarks

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