Supported Houdini Items

Unfortunately Houdini has a variety of ways in which it can respond to various types of events. While some of the more recent ones are explicitly defined Python callbacks, most of the handling is done by legacy disk-based event scripts. Adding to the confusion, these files can be placed in multiple places and also work to override default versions shipped with Houdini itself. Below you’ll find a description of the various event types that you-can-call-me-houdini supports.
