Line Connection Renderer

Line Connection Renderer

Renders lines between nearby particles.

image

Method #

This node renders lines between pairs of nearby particles, giving the impression of a mesh-like structure. The connection pairs are determined by locating particles that are near to each other using a spatial grid. This grid may be scaled by connecting a node to the Bounding Box input, changing the spawning behaviour and potentially affecting performance. Once connected, particles remain joined by a line for a period of time unless one of the particles dies.

Parameters

These properties control the core behaviours of the node.

ParameterDetails
Particle AlphaChange the alpha value for the particles.
Luminance RandomnessControl how much randomness is in the luminance of the rendered particles.
Sort Key ValueBiases the depth-based render order, to force the particle system to be drawn before or after other objects in the scene.
Depth BiasOffsets particles in depth so they are closer or further away from the camera, changing the point at which they intersect with the rest of the scene.
Distance ThresholdMaximum distance a line can be drawn at.
Min DistanceMaximum distance a line can be drawn at.
Particle Use AmountPercentage of particles that can be used by the node.
Line ThicknessEdit the thickness of the line rendered. Only functions if “Use Thick Lines” is enabled.
Depth Of Field AmountHow much depth of field effects the particles.
Line Connection LifetimeLength of time a line between two points can exist.
Affected RadiusThe radius of the area of space within which connections may be generated.
Max X DifferenceThe maximum separation of particles in the X axis that can be connected.
Max Y DifferenceThe maximum separation of particles in the Y axis that can be connected.
Max Z DifferenceThe maximum separation of particles in the Z axis that can be connected.
Cast ShadowsControl whether shadows are cast.
Sort ParticlesToggle whether the particles are sorted by depth from camera from back to front before rendering, enabling transparent particles to be rendered correctly.
Blend ModeEdit the blend mode used for the particles. See Blend Modes for details.
Use Thick LinesToggle whether the lines have 3D thickness, or not.
Max Lines Per ParticleMaximum number of lines that can be drawn from each particle.

Inputs

NameDescriptionTypical Input
Bounding BoxLimit the area for which shadow casting will be calculated.Bounding Box
Affected Centre PositionControls the centre position of a radial area of space where the connections may be generated.Null
Rendered EmittersSpecify which emitters are rendered using this renderer. By default, all emitters connected to the same particle root as the renderer are rendered.Primitive Emitter
Transform ModifierApply the transforms of another node to this node.Null
Target NodeModifiy the rotations of the node to always direct the z axis towards the input.Null
Local Transform OverrideApply the transforms of another node to this node, relative to its parent.Null
