Line Renderer
Updated: 19 Sep 2025
Renders lines between pairs of particles.
Line Renderer
Method #
This node renders lines between particles and other points, which can be other particles or a set position in space.
Parameters
These properties control the core behaviours of the node.
Parameter Details 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.
Line Origin
Where each line is drawn from.
- Random Particles : Pick a random particle to start the line from.
- Null : All lines with start at the position of the Null connected to the “Line Origin” input.
- Emission Sequence : Connect lines based on when the particles are emitted.
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.

| Name | Description | Typical Input |
|---|---|---|
| Line Origin | Origin of the lines when “Line Origin” is set to “Null”. | Null |

| Transform Modifiers | Apply the transforms of another node to this node. | Null |
| Target Node | Modifiy the rotations of the node to always direct the z axis towards the input. | Null |
