# D3D12_RAYTRACING_SHADER_CONFIG (XBOX Series consoles)

> A state subobject that represents a shader configuration.

A state subobject that represents a shader configuration.

## Syntax

```cpp theme={null}
typedef struct D3D12_RAYTRACING_SHADER_CONFIG
{
    UINT MaxPayloadSizeInBytes;
    UINT MaxAttributeSizeInBytes;
} D3D12_RAYTRACING_SHADER_CONFIG
```

### Members

*MaxPayloadSizeInBytes*\
Type: UINT

The maximum storage for scalars (counted as 4 bytes each) in ray payloads in raytracing pipelines that contain this program.

*MaxAttributeSizeInBytes*\
Type: UINT

The maximum number of scalars (counted as 4 bytes each) that can be used for attributes in pipelines that contain this shader. The value cannot exceed [D3D12\_RAYTRACING\_MAX\_ATTRIBUTE\_SIZE\_IN\_BYTES](https://learn.microsoft.com/en-us/windows/desktop/direct3d12/constants).

## Remarks

A raytracing pipeline needs one raytracing shader configuration.  If multiple shader configurations are present, such as one in each collection to enable independent driver compilation for each one, they must all match when combined into a raytracing pipeline.

## Requirements

**Header:** d3d12\_xs.h\
**Library:** d3d12\_xs.lib\
**Supported Platforms**: XBOX Series consoles
