D3D12DDI_RAYTRACING_SHADER_CONFIG_0054 structure (d3d12umddi.h)

Describes the ray tracing shader configuration.

Syntax

typedef struct D3D12DDI_RAYTRACING_SHADER_CONFIG_0054 {
  UINT MaxPayloadSizeInBytes;
  UINT MaxAttributeSizeInBytes;
} D3D12DDI_RAYTRACING_SHADER_CONFIG_0054;

Members

MaxPayloadSizeInBytes

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

MaxAttributeSizeInBytes

The maximum number of scalars (counted as 4 bytes each) that can be used for attributes in pipelines that contain this shader.

Remarks

A ray tracing pipeline needs one ray tracing 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 ray tracing pipeline.
