Справка Houdini на русском Nodes Geometry nodes

HeightField Layer Clear geometry node

Sets all values in a heightfield layer to 0.

Tip

To flood a layer with a value other than zero, you can use the Heightfield node to create a new heightfield with the default value, or use a Heightfield Wrangle node to modify an existing layer. For example, to set all values in the foo layer to 2.0, use the snippet:

@foo = 0;

Parameters

Number of clears

How many layers to clear.

Layer #

The name of the layer to clear.
