# hbmspace:limit_noise

One limit noise of the legacy blended terrain noise.

The density function samples one 16-octave limit noise at $(x \cdot 684.412 \cdot s_{xz}, y \cdot 684.412 \cdot s_y, z \cdot 684.412 \cdot s_{xz})$, scaled to about $\pm 2$. Eve and Tekto use it in place of `minecraft:overworld/base_3d_noise`.

## Fields
