This node renders lines between pairs of particles that neighbour each other in emission order. This is typically used in conjunction with emitters that spawn particles in an ordered fashion so that lines are coherent; otherwise the lines that are created may appear random.

Particles can be sorted in back to front rendering order if Sort Particles is enabled, allowing transparent particles to render and blend together correctly. The Blend Mode parameter is used to control the blend mode between individual particles and also between the particles and the rest of the scene. The Particle Alpha parameter can be used to control the transparency of individual particles, scaling the alpha value already on the particle’s colour channel. Lines may be rendered as thin single pixel lines, or thickened and rendered as quads with softened edges, determined by the Use Thick Lines parameter. When rendered as thick lines the line thickness may be controlled by the Line Thickness parameter.

Name Description
Texture Select a texture to be rendered at each particles position.
Line Thickness Edit the thickness of the line rendered. Only functions if Use Thick Lines is turned on.
Particle Alpha Change the alpha value for the particles.
Depth Of Field Amount How much depth of field effects the particles.
Luminance Randomness Control how much randomness is in the luminance of the rendered particles.
Screen Size Limits The minimum and maximum size of the rendered particle in normalised screen coordiates.
Sort Key Value Biases the depth-based render order, to force the particle system to be drawn before or after other objects in the scene.
Depth Bias Offsets 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.
Lit Control whether the particles are lit.
Cast Shadows Control whether shadows are cast.
Sort Particles Toggle whether the particles are sorted by depth from camera from back to front before rendering, enabling transparent particles to be rendered correctly.
Blend Mode Edit the blend mode used for the particles. See Blend Modes for details.
Use Thick Lines Toggle whether the lines have 3D thickness, or not.

Target Node Always faces the x-axis towards the inputs anchor point. Null
Local Transform Override Override the transformation values of the node, relative to its parent. Null
