# PSYS_PART_RIBBON_MASK

*LSL constant*

```lsl
integer PSYS_PART_RIBBON_MASK = 0x400;
```

Particle flag that joins emitted particles into a continuous ribbon strip. Textures stretch to join adjacent edges. Width is controlled by the 'x' start/end scale; 'y' controls maximum visibility distance. Ribbon segments are not camera-facing, mimic the emitter's Z-axis, and require horizontal movement to render.
