Houdini - ShotGrid - Loading publishes You can load in files other people have published by going to the "ShotGrid" -> "Load..." A lot of file types can be loaded into Houdini, but here's a short list of the main loading operations you'll be using: USD files can be loaded into your stage through a Reference or a Sublayer node. References should be used when the loaded USD needs a new place in your hierarchy, e.g. for assets. Sublayering should be used when the loaded USD is meant as a separate layer in your hierarchy, e.g. our Maya animation publishes, which always go to the Animation layer. Alembic files can be loaded into your Houdini file as an Alembic node in SOPs, inside a SOP Create in your stage and hooked up to a component builder in your stage (for use in our asset shading workflow).  Published textures can be loaded as MaterialX nodes, which can be automatically turned into a Karma material. Check out  this page for more information on our shading workflow.  Loading tools largely unchanged from ShotGrid base implementation.
