The Perlin Ridged node
When to use it
Multi-octave Perlin folded to emphasise sharp ridges. Mountain ranges, cracked earth, anything where FBM looks too rounded.
Ridged noise is biased toward its maximum. Swap it in for an FBM at the same amplitude and the whole field sits higher than it did, so the offset that used to put the surface at ground level now buries it.
Pins
| Pin | Type | Description |
|---|---|---|
Frequency |
Number | How tight the biggest layer is. Everything else is built on top of it. |
Lacunarity |
Number | How much smaller each layer gets. At 2 every layer is half the size of the one before. |
Gain |
Number | How much quieter each layer gets. Low is crisp, high is rough and grubby. |
OffsetX |
Number | Slide the pattern along X. |
OffsetY |
Number | Slide the pattern along Y. |
OffsetZ |
Number | Slide the pattern along Z. |
Seed |
Whole Number | Change this for a different pattern at the same settings. The same seed always gives you the same noise. |
Octaves |
Whole Number | How many layers to stack. Past about 8 you are paying for detail finer than your voxels can show. |
