Houdini 19.5 Shelf tools

Null shelf tool

Creates a null object which can be used to hold a place in a scene, and never renders.

On this page


A Null object can also be used as an End Affector for constructing chains of bones.

It is often used as a parent, which can be used to rotate and transform multiple objects at once.

Null objects can also be used in animation with a Look At. You can set the Camera to look at the null object instead of the actual character so that the camera follows the character but does not move with it. Using the null this way will prevent the camera from moving up and down if a character is jumping.
