> Sets an input or output compute buffer.

## Definition

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

## SetBuffer(int, int, ComputeBuffer)

Sets an input or output compute buffer.

```csharp
public void SetBuffer(int kernelIndex, int nameID, ComputeBuffer buffer)
```

### Parameters

**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): For which kernel the buffer is being set. See [ComputeShader.FindKernel](/engine/6000.6/script-reference/unityengine/computeshader/findkernel.md).**** (\[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 it.**** (\[ComputeBuffer]\(/engine/6000.6/script-reference/unityengine/computebuffer)): Buffer to set.

### Remarks

Buffers and textures are set per-kernel. Use [ComputeShader.FindKernel](/engine/6000.6/script-reference/unityengine/computeshader/findkernel.md) to find kernel index by function name.

Setting a compute buffer to a kernel will leave the append/consume counter value unchanged. To set or reset the value, use [ComputeBuffer.SetCounterValue](/engine/6000.6/script-reference/unityengine/computebuffer/setcountervalue.md) or [GraphicsBuffer.SetCounterValue](/engine/6000.6/script-reference/unityengine/graphicsbuffer/setcountervalue.md).

## SetBuffer(int, int, GraphicsBuffer)

Sets an input or output compute buffer.

```csharp
public void SetBuffer(int kernelIndex, int nameID, GraphicsBuffer buffer)
```

### Parameters

**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): For which kernel the buffer is being set. See [ComputeShader.FindKernel](/engine/6000.6/script-reference/unityengine/computeshader/findkernel.md).**** (\[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 it.**** (\[GraphicsBuffer]\(/engine/6000.6/script-reference/unityengine/graphicsbuffer)): Buffer to set.

### Remarks

Buffers and textures are set per-kernel. Use [ComputeShader.FindKernel](/engine/6000.6/script-reference/unityengine/computeshader/findkernel.md) to find kernel index by function name.

Setting a compute buffer to a kernel will leave the append/consume counter value unchanged. To set or reset the value, use [ComputeBuffer.SetCounterValue](/engine/6000.6/script-reference/unityengine/computebuffer/setcountervalue.md) or [GraphicsBuffer.SetCounterValue](/engine/6000.6/script-reference/unityengine/graphicsbuffer/setcountervalue.md).
