Sidefx Houdini 20.5.278 May 2026

The heart of Houdini is its attribute system. This build introduces faster spreadsheet filtering and new VEX functions for handling array attributes, reducing boilerplate code in wrangle nodes. For procedural modelers, this makes tasks like transferring color data between hi-poly and low-poly meshes significantly less tedious.

This version is part of the 20.5 production series, focusing on stability, workflow refinement, and specific high-impact tools. While 20.5 introduced major overhauls (like Karma XPU and APEX), version represents a mature, stable release with key bug fixes and performance tweaks. SideFX Houdini 20.5.278
