###### Build modes

The drop-down list to the bottom right stands for the

“build modes”. This sets for which noise values nodes
|

will be generated:
|
||||
|
||||
* Auto: In 2D mode, generate nodes for every value,

in 3D mode, only generate nodes for high values

* All: Generate nodes for every value

* High only: Only generate nodes for high values

* Low only: Only generate nodes for low values
