Maya transition guide
Welcome
Maya™ to Houdini 9 transition guide
Welcome to Houdini! This guide shows a few basic translations between Maya™ and Houdini to help Maya users get up to speed more quickly.
We hope that Maya users will use this guide as starting point, and then explore Houdini’s unique node-based procedural workflow and all the benefits it has that don’t have equivalents in Maya.

Houdini treats objects and components slightly differently than Maya™.
In Maya, every piece of geometry you create is an object, and you combine objects using modeling commands to create new objects. An object’s construction history lets you access the nodes that contributed to the object.
In Houdini, the Geometry Container objects represents animate-able models, alongside other object types such as lights, cameras, and bones. Geometry container objects have a network of surface nodes inside that define the object’s geometry.
In Houdini, you often alternate between creating, combining, parenting, and animating objects at the Scene level, and modeling using surface nodes inside Geometry container objects (the Geometry level).
