Detailed Description

Rendering resources needed to render an individual static mesh LOD. This structure is ref counted to allow the LOD streamer to evaluate the number of readers to it (readers that could access the CPU data). Because the stream out clears the CPU readable data, CPU code that samples it must ensure to only reference LODs above CurrentFirstLODIdx.

Member Data Documentation

AdditionalIndexBuffers

FAdditionalStaticMeshIndexBuffers* FStaticMeshLODResources::AdditionalIndexBuffers = nullptr

AreaWeightedSampler

FStaticMeshAreaWeightedSectionSampler FStaticMeshLODResources::AreaWeightedSampler

Allows uniform random selection of mesh sections based on their area.

AreaWeightedSectionSamplers

FStaticMeshSectionAreaWeightedTriangleSamplerArray FStaticMeshLODResources::AreaWeightedSectionSamplers

Allows uniform random selection of triangles on each mesh section based on triangle area.

AreaWeightedSectionSamplersBuffer

FStaticMeshSectionAreaWeightedTriangleSamplerBuffer FStaticMeshLODResources::AreaWeightedSectionSamplersBuffer

Allows uniform random selection of triangles on GPU. It is not cooked and serialised but created at runtime from AreaWeightedSectionSamplers when it is available and static mesh bSupportGpuUniformlyDistributedSampling=true

bBuffersInlined

uint32 FStaticMeshLODResources::bBuffersInlined

True if vertex and index data are serialized inline

bHasColorVertexData

uint32 FStaticMeshLODResources::bHasColorVertexData

bHasDepthOnlyIndices

uint32 FStaticMeshLODResources::bHasDepthOnlyIndices

True if the depth only index buffers contained data at init. Needed as it will not be available to the CPU afterwards.

bHasReversedDepthOnlyIndices

uint32 FStaticMeshLODResources::bHasReversedDepthOnlyIndices

True if the reversed index buffers contained data at init. Needed as it will not be available to the CPU afterwards.

bHasReversedIndices

uint32 FStaticMeshLODResources::bHasReversedIndices

True if the reversed index buffers contained data at init. Needed as it will not be available to the CPU afterwards.

bHasWireframeIndices

uint32 FStaticMeshLODResources::bHasWireframeIndices

bIsOptionalLOD

uint32 FStaticMeshLODResources::bIsOptionalLOD

True if this LOD is optional. That is, vertex and index data may not be available

DepthOnlyIndexBuffer

FRawStaticIndexBuffer FStaticMeshLODResources::DepthOnlyIndexBuffer

Index buffer resource for rendering in depth only passes.

DepthOnlyNumTriangles

uint32 FStaticMeshLODResources::DepthOnlyNumTriangles

DistanceFieldData

class FDistanceFieldVolumeData* FStaticMeshLODResources::DistanceFieldData = nullptr
