Houdini 16.5 Digital assets

Install and manage digital assets

Asset libraries

Digital asset definitions are saved in digital asset library files with a .hda extension. (Older versions of Houdini saved libraries with a .otl extension.) Houdini will load the assets from any library files it finds in HOUDINIPATH/hda and make them available to the user alongside the "factory" nodes included with Houdini.

  • A large studio can put site-wide assets in a central, networked directory and make sure all artists have that directory in their $HOUDINI_PATH.

  • You can put assets specific to a project in $JOB/hda. See project management for how to set up $JOB.

  • You can put your own personal assets in the hda directory in your user account’s Houdini preferences. This is the default location when you create a new asset.

To...Do this

Manually install the asset(s) in a library file

Choose File ▸ Import ▸ Houdini digital asset.

Manually uninstall an asset library

  1. Choose Windows ▸ Operator Type Manager.

  2. Right-click the library name and choose Uninstall.

Note

If you are using assets containing other assets (for example, a character asset containing a skeleton setup asset), you need to make sure the library files for all assets are installed, not just the "top" asset. If nested assets are not installed, the top level node will error.

If you install the libraries containing the missing nodes, the top-level asset will automatically start working (you don’t need to restart Houdini).
