Houdini Digital Assets (HDAs) are an extremely powerful way of extending

Houdini. With these, you can package up all kinds of custom tools and hand

them off to other users, or to yourself, for later use. You can hide the grimy

details, so that the user just deals with the problem as he would like to think

of it. You can embed any arbitrary data, including scripts, images or a list of all

your favorite pizza restaurants – they don’t care. This chapter deals with getting

more out of these amazing tools.
