Renders lines between nearby particles.
Updated: 15 Sep 2026
Renders lines between nearby particles.
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.
These properties control the core behaviours of the node.

| Parameter | Details |
|---|---|
| Colour Texture | Defines the base color of the material’s surface. It represents the surface color under neutral, uniform lighting. |
| Diffuse Map | Specifies the color of light that scatters off the surface in all directions. It is functionally similar to the Colour Texture and is a core component of a material’s appearance. |
| Specular Map | Controls the color and intensity of shiny reflections (specular highlights). Brighter areas on the map indicate a more reflective and shinier surface. |
| Emissiveness Map | Determines which parts of a material appear to glow or emit their own light. Brighter values cause the surface to act as a light source. |
| Metallicness Map | A grayscale map to define how ‘metal-like’ a surface is. White values represent pure metal, while black values represent non-metals. |
| Roughness Map | A grayscale map that controls the roughness of the surface. Black represents a smooth, mirror-like surface with sharp reflections, while white represents a rough surface with blurry, diffuse reflections. |
| Normal Map | Adds surface detail like bumps and scratches without adding more polygons to the model. It simulates how light would interact with a more complex surface, creating the illusion of depth. |
| Displacement Map | Physically displaces the vertices of the model’s geometry based on the map’s values. Unlike a Normal Map, this creates real geometric detail that affects the model’s silhouette. |
| Alpha Map | A grayscale map that controls the transparency of the material. Black areas are fully transparent, white areas are fully opaque, and gray values create semi-transparency. |
| Ambient Occlusion Map | Adds subtle, soft shadows to areas that are occluded from ambient light, such as creases and crevices. This enhances realism and adds perceived depth to the model. |
| Subsurface Colour Map | Defines the color of light after it has scattered beneath the surface of a translucent material, such as skin, wax, or marble. |
| Subsurface Weight Map | Controls the intensity of the subsurface scattering effect across the material, defining how much light penetrates and scatters within the surface. |
| UV Texture Filter Mode |
Determines the algorithm used for sampling texture pixels when viewed at different angles and distances.
|
| Diffuse Map -> AO | A setting to use the Diffuse or Colour map to contribute to the Ambient Occlusion calculation, often darkening areas based on the base color. |
| Texture Mip Bias | An offset that adjusts which mipmap level is used for a texture. Negative values can sharpen distant textures, while positive values can blur them. |
