Noise persistence

How much the fine details count compared with the texture's big wave. Low gives a soft texture; high, a rough one.

How it works

Each noise octave weighs a fraction of the one before, and this value is that fraction. With 0.5 (default), each level weighs half as much as the previous one; with 0.2, the fine details barely show; with 0.9, they weigh almost as much as the big wave.

In practice, it's the “roughness” knob for coherent noises.

When to change it

  • To start: 0.5 (default).
  • A smooth, rounded river stone: 0.2–0.3.
  • A rough rock or tree bark: 0.7–0.9.

What Bambu Studio says

The decay rate for higher octaves of the coherent noise. Lower values will result in smoother noise.
