Houdini to Unreal with USD: A Tested Stage, HDA and Material Pipeline

Alicia tested Houdini 22.0.429 and Unreal Engine 5.8.3 to evaluate OpenUSD pipelines. The research distinguishes between using a USD Stage for composed scenes and Houdini Engine for procedural tools. Testing involved independent fixtures, including a referenced flower and a 100-copy scatter, with data verified via native Unreal components. Additionally, experiments in Houdini Solaris demonstrated OpenUSD efficiency by using payloads and entry layers to update multiple asset references across different shot layers within a garden scene.
