Variables

  Type Name Description
Public variable bool bConstantTopology Flag whether or not this object has constant topology (used for eligibility for PCA compression)
Public variable bool bConstantTransformation Flag whether or not this object has a constant world matrix (used whether to incorporate into PCA compression)
Public variable bool bConstantVisibility Flag whether or not this object has a constant visibility value across the entire animated range
Protected variable bool bFirstFrameVisibility Whether or not the mesh is visible in the first Frame
Protected variable bool bReturnFirstSample Whether or not to just return FirstSample
Protected variable bool bReturnTransformedFirstSample Whether or not to just return the transformed FirstSample
Public variable bool bShouldImport Whether or not this Mesh object should be imported
Public variable FBoxSphereBounds ChildBounds  
Public variable TArray< FString > FaceSetNames Array of face set names found for this object
Protected variable FAbcMeshSample * FirstSample Initial mesh sample for this object in first frame with available data
Protected variable const Alembic::AbcGeom::IPolyMesh PolyMesh Alembic representation of this object
Protected variable FAbcMeshSample *[MaxNumberOfResidentSamples] ResidentSamples Resident set of Mesh Samples for this object, used for parallel reading of samples/frames
Protected variable bool[MaxNumberOfResidentSamples] ResidentVisibilitySamples  
Protected variable ESampleReadFlags SampleReadFlags Bitmask read flag used for skipping constant vertex attributes while reading samples
Protected variable const Alembic::AbcGeom::IPolyMeshSchema Schema Schema extracted from Poly Mesh object
Public variable FBoxSphereBounds SelfBounds Cached self and child bounds for entire duration of the animation
Protected variable FAbcMeshSample * TransformedFirstSample Initial mesh sample for this object in first frame with available data, transformed by first available matrix
