Variables

  Type Name Description
Public variable UProperty Category, EditAnywhere ENiagaraSpriteAlignment Alignment Imagine the particle texture having an arrow pointing up, these modes define how the particle aligns that texture to other particle attributes.
Public variable UProperty Category, EditAnywhere, Meta float AlphaThreshold Alpha channel values larger than the threshold are considered occupied and will be contained in the bounding geometry.
Public variable UProperty Category, EditAnywhere uint8: 1 bEnableCameraDistanceCulling Enables frustum culling of individual sprites
Public variable UProperty Category, EditAnywhere TEnumAsByte< enum ESubUVBoundingVertexCount > BoundingMode More bounding vertices results in reduced overdraw, but adds more triangle overhead.
