Groom

The Groom sampler reads an attribute painted on a groom, so you can control any parameter by painting. For example, paint a curl attribute on the groom and connect a Groom sampler that reads it to a Curl node's Curl parameter: the fur curls wherever you painted.

It outputs a single value, read at the rest position of each fibre or point, so the value stays put as the character moves.

Parameters

Parameter	Description
Groom	The groom to sample.
Attribute	The name of the float attribute to sample. length is a special case: it doesn't need to exist on the groom, and uses the length of each strand.
Sample Count	How many nearby strands are sampled and weighted. The default is 9, but sometimes you'll want a single sample, for example to pick instance or feather IDs.
