Houdini Digital Assets (HDAs) are a general mechanism to build reusable and updatable compounds in the various Houdini contexts. Digital assets can capture the functionality of a network as a tool or material with a customized interface that can be made available to other users.
HDAs can be created at VOP or SHOP level by collecting the network in a subnet, saving as a digital asset, and then adding parameters from nodes inside the asset as parameters or handles on the asset itself.
