To answer an obvious question off the top - yes we recorded the session, and it will be posted in the next day or two, along with scene files Jeff used during the session. I'll send out the usual email notification when it's ready.

If you have comments / questions about the HDA Building webinar - you can post them here and Jeff will reply…


In this presentation we will focus on Houdini Digital Asset or HDA construction from basics to in depth details. All live in Houdini. All the time building up HDAs to demonstrate all features.

HDAs are a powerful way to turn your clever networks in to a single operator that can be referenced millions of times by any numbrer of users. HDAs can be simple nodes with simple uses or complex nodes that do an entire effect.

The webinar will look at planning and design of networks for HDAs, making HDAs and deploying HDAs for single users or for entire facilities.

Customizing HDAs is a big part of the work. This requires an in-depth look at the Edit Operator Type Properties dialog as this is the key tool for tool construction.

Managing HDAs is also covered. HDAs are automatically added to context tab menus and you can install assets directly on the shelf.
You may have ten, hundreds or thousands of assets to manage in Houdini. You can have multiple assets inside a single .hda file will be discussed. There are command-line tools to help manage HDAs along with three key ways of configuring your enviornment. Versioning HDAs is also covered along with HDA diff'ing.

Finally examples of HDAs will be given for all the various network types including Objects, SOPs, ROPs, Materials, VOPs and more.
