# SetRayTracingFloatParams

> Adds a command to set multiple consecutive float parameters on a RayTracingShader.

## Definition

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

## SetRayTracingFloatParams(RayTracingShader, string, float\[])

Adds a command to set multiple consecutive float parameters on a [RayTracingShader](/engine/6000.5/script-reference/unityengine/rendering/raytracingshader.md).

```csharp
public void SetRayTracingFloatParams(RayTracingShader rayTracingShader, string name, params float[] values)
```

### 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.**** (\[float\[]]\(https\://learn.microsoft.com/dotnet/api/system.single)): Values to set.

### Remarks

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

This function can be used to set float vector, float array or float vector array values. For example, `float4 myArray[4]` in the ray tracing shader can be filled by passing 16 floats.

## SetRayTracingFloatParams(RayTracingShader, int, float\[])

Adds a command to set multiple consecutive float parameters on a [RayTracingShader](/engine/6000.5/script-reference/unityengine/rendering/raytracingshader.md).

```csharp
public void SetRayTracingFloatParams(RayTracingShader rayTracingShader, int nameID, params float[] values)
```

### 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.**** (\[float\[]]\(https\://learn.microsoft.com/dotnet/api/system.single)): Values to set.
