Gravity 


Hair with little gravity applied (left) and stronger gravity (right)

This node is a helper operator to allow you to cheat the effect of gravity on hair quickly and intuitively. A special slope graph lets you adjust how much gravity is applied along the length of the strands (this can also be controlled through a map). You can also control gravity direction, global amount, and even add collision objects to prevent hair from going into them.

  • Change Gravity Direction Can be used to indicate the direction of the gravity force. Rotate the gizmo to change the direction.
 

Parameters 

 

Strand Group 

Specifies a strand group to which this operator is applied. Only strands within the specified group will be modified. Using an empty value will modify all strands.

 

Force 

The amount of gravity force applied to the hair.

 

Force Channel 

Use a Guide Channel to control the Force amount.
