ParticleModuleTypeDataAnimTrail Provides the base data for animation-based trail emitters.
Properties
Property group 'Anim'
ControlEdgeName
Type: name
The number of sheets to render for the trail.
Property group 'Rendering'
bRenderGeometry
Type: bool
If TRUE, render the trail geometry (this should typically be on)
Default value: True
bRenderSpawnPoints
Type: bool
If TRUE, render stars at each spawned particle point along the trail
bRenderTangents
Type: bool
If TRUE, render a line showing the tangent at each spawned particle point along the trail
bRenderTessellation
Type: bool
If TRUE, render the tessellated path between spawned particles
DistanceTessellationStepSize
Type: float
The distance step size for tessellation.
- Tessellation Points = Trunc((Distance Between Spawned Particles) / DistanceTessellationStepSize))
Default value: 10.0
TangentTessellationScalar
Type: float
The tangent scalar for tessellation. Angles between tangent A and B are mapped to [0.0f .. 1.0f] This is then multiplied by TangentTessellationScalar to give the number of points to tessellate
TilingDistance
Type: float
The (estimated) covered distance to tile the 2nd UV set at. If 0.0, a second UV set will not be passed in.
Property group 'Trail'
bClipSourceSegement
Type: bool
If true, do not join the trail to the source position
Default value: True
bDeadTrailsOnDeactivate
Type: bool
If true, when the system is deactivated, mark trails as dead. This means they will still render, but will not have more particles added to them, even if the system re-activates...
Default value: True
bEnablePreviousTangentRecalculation
Type: bool
If true, recalculate the previous tangent when a new particle is spawned
Default value: True
bTangentRecalculationEveryFrame
Type: bool
If true, recalculate tangents every frame to allow velocity/acceleration to be applied
SheetsPerTrail
Type: int
The number of sheets to render for the trail.
Default value: 1
