# SetRayTracingVectorParam

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

## Definition

* **Type:** Method
* **Namespace:** [UnityEngine.Rendering](/engine/6000.5/script-reference/unityengine/rendering.md)
* **Assembly:** UnityEngine.CoreModule

## SetRayTracingVectorParam(RayTracingShader, string, Vector4)

Adds a command to set a vector parameter on a [RayTracingShader](/engine/6000.5/script-reference/unityengine/rendering/raytracingshader.md).

```csharp
public void SetRayTracingVectorParam(RayTracingShader rayTracingShader, string name, Vector4 val)
```

### Parameters

**** (\[RayTracingShader]\(/engine/6000.5/script-reference/unityengine/rendering/raytracingshader)): [RayTracingShader](/engine/6000.5/script-reference/unityengine/rendering/raytracingshader.md) to set parameter for.**** (\[string]\(https\://learn.microsoft.com/dotnet/api/system.string)): Name of the variable in shader code.**** (\[Vector4]\(/engine/6000.5/script-reference/unityengine/vector4)): Value to set.

### Remarks

Only shaders defined in the .raytrace file can access the vector you designate as the argument for this method. To make this vector accessible to all ray tracing shader types (closest hit, any hit, or miss, for example), call the [CommandBuffer.SetGlobalVector](/engine/6000.5/script-reference/unityengine/rendering/commandbuffer/setglobalvector.md) method instead.

## SetRayTracingVectorParam(RayTracingShader, int, Vector4)

Adds a command to set a vector parameter on a [RayTracingShader](/engine/6000.5/script-reference/unityengine/rendering/raytracingshader.md).

```csharp
public void SetRayTracingVectorParam(RayTracingShader rayTracingShader, int nameID, Vector4 val)
```

### Parameters

**** (\[RayTracingShader]\(/engine/6000.5/script-reference/unityengine/rendering/raytracingshader)): [RayTracingShader](/engine/6000.5/script-reference/unityengine/rendering/raytracingshader.md) to set parameter for.**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): Property name ID. Use [Shader.PropertyToID](/engine/6000.5/script-reference/unityengine/shader/propertytoid.md) to get this ID.**** (\[Vector4]\(/engine/6000.5/script-reference/unityengine/vector4)): Value to set.

### Remarks

Only shaders defined in the .raytrace file can access the vector you designate as the argument for this method. To make this vector accessible to all ray tracing shader types (closest hit, any hit, or miss, for example), call the [CommandBuffer.SetGlobalVector](/engine/6000.5/script-reference/unityengine/rendering/commandbuffer/setglobalvector.md) method instead.
