## SetComputeBufferParam(ComputeShader, int, int, ComputeBuffer)

Adds a command to set an input or output buffer parameter on a [ComputeShader](/engine/6000.0/script-reference/unityengine/computeshader.md).

```csharp
public void SetComputeBufferParam(ComputeShader computeShader, int kernelIndex, int nameID, ComputeBuffer buffer)
```

### Parameters

**** (\[ComputeShader]\(/engine/6000.0/script-reference/unityengine/computeshader)): [ComputeShader](/engine/6000.0/script-reference/unityengine/computeshader.md) to set parameter for.**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): Which kernel the buffer is being set for. See [ComputeShader.FindKernel](/engine/6000.0/script-reference/unityengine/computeshader/findkernel.md).**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): Property name ID. Use [Shader.PropertyToID](/engine/6000.0/script-reference/unityengine/shader/propertytoid.md) to get this ID.**** (\[ComputeBuffer]\(/engine/6000.0/script-reference/unityengine/computebuffer)): Buffer to set.

### Remarks

Buffers and textures are set per-kernel. Use [ComputeShader.FindKernel](/engine/6000.0/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/6000.0/script-reference/unityengine/computebuffer/setcountervalue.md) or [GraphicsBuffer.SetCounterValue](/engine/6000.0/script-reference/unityengine/graphicsbuffer/setcountervalue.md).
