A library of Digital Assets, Presets and Scripts for SideFX Houdini. Video overviews of several tools may be found here

The /otls folder contains many HDAs (mostly SOP level) which are available from the 'aelib' context menu.

Assets which are mostly complete and stable are indicated by this icon:

Assets which are in progress are indicated by this icon:

WIP assets are usually missing some functionality or have known bugs/issues.


  • Download the repository
  • Extract and move into the Houdini config directory
  • Append the provided houdini.env file to your own houdini.env

Evironment variables used:

  • HOUDINI_OTLSCAN_PATH: the assets
  • HOUDINI_GALLERY_PATH: gallery items
  • HOUDINI_TOOLBAR_PATH: shelf tools
  • HOUDINI_VEX_PATH: custom Vex files (required in some assets)


The structure of this library is inspired by qLib - a large open source Houdini library - Most of the assets found in Aelib will work in isolation. However, a few tools do make use of qLib so it is highly recommended that this is installed alongside Aelib.
