struct FRayTracing

Type	Name	Description
uint32	AccelerationStructureAlignment	Required alignment for ray tracing acceleration structures.
uint32	InstanceDescriptorSize	Size of an individual element in the ray tracing instance buffer.
uint32	ScratchBufferAlignment	Required alignment for ray tracing scratch buffers.
uint32	ShaderTableAlignment	Required alignment for ray tracing shader binding table buffer.
bool	Supported	Whether or not the RHI supports ray tracing on current hardware (acceleration structure building and new ray tracing-specific shader types).
bool	SupportsAMDHitToken	Whether or not the RHI supports the AMD Hit Token extension.
bool	SupportsAsyncBuildAccelerationStructure	Whether or not the RHI supports async building ray tracing acceleration structures.
bool	SupportsDispatchIndirect	Whether or not the RHI supports indirect ray tracing dispatch commands.
bool	SupportsInlineRayTracing	Whether or not the RHI supports inline ray tracing in compute shaders, without a full ray tracing pipeline.
bool	SupportsPSOAdditions	Whether or not the RHI supports adding new shaders to an existing RT PSO.
bool	SupportsShaders	Whether or not the RHI supports ray tracing raygen, miss and hit shaders (i.e. full ray tracing pipeline).
