Variables

  Type Name Description
Public variable uint32 AccelerationStructureAlignment Required alignment for ray tracing acceleration structures.
Public variable uint32 InstanceDescriptorSize Size of an individual element in the ray tracing instance buffer.
Public variable bool RequiresInlineRayTracingSBT Whether or not the RHI requires a SBT for inline ray tracing in compute shaders to fetch geometry information
Public variable uint32 ScratchBufferAlignment Required alignment for ray tracing scratch buffers.
Public variable uint32 ShaderTableAlignment Required alignment for ray tracing shader binding table buffer.
Public variable bool Supported Whether or not the RHI supports ray tracing on current hardware (acceleration structure building and new ray tracing-specific shader types).
Public variable bool SupportsAMDHitToken Whether or not the RHI supports the AMD Hit Token extension.
Public variable bool SupportsAsyncBuildAccelerationStructure Whether or not the RHI supports async building ray tracing acceleration structures.
Public variable bool SupportsDispatchIndirect Whether or not the RHI supports indirect ray tracing dispatch commands.
Public variable bool SupportsInlinedCallbacks Whether or not the RHI supports inlined callbacks
Public variable bool SupportsInlineRayTracing Whether or not the RHI supports inline ray tracing in compute shaders, without a full ray tracing pipeline.
Public variable bool SupportsLooseParamsInShaderRecord Wether an extra uniform buffer parameter is required when loose parameters are present, or if they are stored directly in the shader record.
Public variable bool SupportsPSOAdditions Whether or not the RHI supports adding new shaders to an existing RT PSO.
Public variable bool SupportsShaders Whether or not the RHI supports ray tracing raygen, miss and hit shaders (i.e. full ray tracing pipeline).
