Import libraries

Asset libraries

Digital assets are stored in digital asset library files, with a .hda extension. (Older versions of Houdini used a .otl extension.) Houdini loads any .hda (or .otl) files it finds in HOUDINIPATH/otls.

Steps:

 1) Create Subnet

 2) Define Parameters and Save .otl
