Syntax

struct FStaticMeshLODResources : public FRefCountBase

Remarks

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.

Variables

FAdditionalStat...	AdditionalIndexBuffers
FStaticMeshArea...	AreaWeightedSampler	Allows uniform random selection of mesh sections based on their area.
FStaticMeshSect...	AreaWeightedSectionSamplers	Allows uniform random selection of triangles on each mesh section based on triangle area.
FStaticMeshSect...	AreaWeightedSectionSamplersBuffer	Allows uniform random selection of triangles on GPU.
uint32: 1	bBuffersInlined	True if vertex and index data are serialized inline
uint32: 1	bHasAdjacencyInfo	True if the adjacency index buffer contained data at init.
uint32: 1	bHasColorVertexData
uint32: 1	bHasDepthOnlyIndices	True if the depth only index buffers contained data at init.
uint32: 1	bHasRayTracingGeometry	True if the ray tracing resources struct contained data at init.
