Sidefx Houdini 20.5.278 _hot_

For the most stable experience in the 20.5 cycle, SideFX recommends updating to the latest Production Build (currently 20.5.332 or higher) to benefit from bug fixes implemented after the .278 gold release. What's New in H20.5 - SideFX

Community discussions highlighted important performance improvements in the 20.5 series. Reddit users reported significant startup time enhancements, with version 20.5.278 showing initial startup times of 1:00-1:15, while subsequent daily builds like 20.5.303 reduced startup time to 0:45.

A dedicated SOP to convert car geometry into a dynamic rig with suspension and motor constraints.

Houdini is an early build of the Houdini 20.5 release cycle. While version 20.5 introduced major groundbreaking tools, build .278 specifically became notable for a reported issue on macOS where it altered point counts when generating high-res mountain geometry in certain examples.

Enhanced USD-based workflows, with improved Karma XPU performance and faster rendering capabilities.

Houdini 20.5.278 is a production-ready point release built on the major Houdini 20.5 architecture. Unlike major version jumps that introduce completely new frameworks, point releases like 20.5.278 focus on production hardening. It resolves critical bugs, eliminates memory leaks, improves multi-threading efficiency, and ensures seamless compatibility with external renderers and pipeline tools. Core Feature Overview

Houdini's reputation rests heavily on its physics solvers. The latest point releases ensure these tools run faster and more reliably. Solver Context Key Capability Production Benefit Sparse gas/smoke simulation Faster compute times, lower RAM overhead. Vellum Cloth/Hair XPBD (Extended Position-Based Dynamics) Stable multi-layered cloth and tearing simulations. FLIP Fluid SOP-based liquid workflows Rapid setup of oceans, splashes, and viscous fluids. Rigid Body (RBD) Bullet solver destruction Real-time fracturing and art-directed debris fields.

The headline feature of this release is , a GPU-accelerated framework for 2D and 3D image processing.

Build 278 showcases the continued integration of APEX, SideFX’s new motion design and character animation framework. Unlike traditional keyframe editors, APEX uses a layered, node-based system that mirrors Houdini’s procedural logic. In version 20.5.278, the APEX graph editor experiences improved undo handling and faster evaluation for complex character rigs, finally making it a viable alternative to native DCC tools for walk cycles and crowd variations.
