For technical directors writing custom SOPs, updates the Houdini Development Kit (HDK) to be fully compatible with Visual Studio 2022 (v17.8+) and GCC 13 on Linux. A notable fix includes the correction of the OP_Node::cook thread-safety flags, eliminating a rare race condition when cooking parallel point clouds.

Released as a production-ready build, version 20.5.278 addresses critical bugs, introduces subtle but powerful workflow enhancements, and stabilizes the new features introduced in the 20.5 cycle. Whether you are simulating a pyro explosion, rigging a game character with KineFX, or generating a sprawling city with terrain tools, this build is the current gold standard for stability and performance.

: From rigid body dynamics to fluid simulations, Houdini offers a comprehensive suite of tools for creating realistic effects.
