Variables

	Name	Description
uint32: 1	bClipSourceSegement	If true, do not join the trail to the source position
uint32: 1	bDeadTrailsOnDeactivate	If true, when the system is deactivated, mark trails as dead.
uint32: 1	bDeadTrailsOnSourceLoss	If true, when the source of a trail is 'lost' (ie, the source particle dies), mark the current trail as dead.
uint32: 1	bEnablePreviousTangentRecalculation	If true, recalculate the previous tangent when a new particle is spawned
uint32: 1	bEnableTangentDiffInterpScale	If this flag is enabled, the system will scale the number of interpolated vertices based on the difference in the tangents of neighboring particles.
uint32: 1	bRenderGeometry	Trail Rendering Variables.If true, render the trail geometry (this should typically be on)
uint32: 1	bRenderSpawnPoints	If true, render stars at each spawned particle point along the trail
uint32: 1	bRenderTangents	If true, render a line showing the tangent at each spawned particle point along the trail
uint32: 1	bRenderTessellation	If true, render the tessellated path between spawned particles
uint32: 1	bSpawnInitialParticle	If true, ribbon will spawn a particle when it first starts moving
uint32: 1	bTangentRecalculationEveryFrame	If true, recalculate tangents every frame to allow velocity/acceleration to be applied
float	DistanceTessellationStepSize	The distance step size for tessellation.
int32	MaxParticleInTrailCount	Max particles per trail
int32	MaxTessellationBetweenParticles	General Trail Variables.
int32	MaxTrailCount	The number of live trails
TEnumAsByte< en...	RenderAxis	The 'render' axis for the trail (what axis the trail is stretched out on) Trails_CameraUp - Traditional camera-facing trail.
int32	SheetsPerTrail	The number of sheets to render for the trail.
float	TangentSpawningScalar	Trail Spawning Variables.
float	TangentTessellationScalar	The tangent scalar for tessellation.
float	TilingDistance	The (estimated) covered distance to tile the 2nd UV set at.
