SideFX Houdini 20.5.278 was the initial production build for the major 20.5 update, released on July 11, 2024. This version introduced several groundbreaking features, most notably the new GPU-accelerated image processing framework, Copernicus, and the MPM multi-physics solver. Key Features of Houdini 20.5

Why .278 Matters to Different Users

  • The VFX Artist: This build excels at large-scale simulation. The Multi-solver workflow (combining FLIP, Pyro, and RBD) sees fewer crashes when writing heavy cache files. The new Gas Upres controls allow pyro simulations to be computed at low resolution and detailed at high resolution with greater fidelity.
  • The Game Developer: Houdini Engine, the plugin that runs Houdini’s logic inside Unreal or Unity, is tightly integrated in 20.5.278. The build fixes a long-standing issue where terrain splat maps would corrupt on re-export. For procedural level generation, this means truly reliable iteration.
  • The Motion Designer: With APEX and new COP (Compositing) tools for managing motion graphics textures, this build offers a non-destructive alternative to After Effects for data visualization and abstract animation. The Spline workflow is notably snappier in the viewport.
