The Perlin FBM 2D node
When to use it
2D multi-octave Perlin. The default terrain noise for heightmap-style generation.
Pair it with Position Z to make a field: amplitude * noise - z. That is the shape both erosion nodes expect to be handed.
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. |
Seed |
Whole Number | Change this for a different pattern at the same settings. |
Octaves |
Whole Number | How many layers to stack. Past about 8 you are paying for detail finer than your voxels can show. |
