Houdini Main Changelogs

20.5.572 | Fixed a bug where an empty mesh may fail to populate if the mesh is no longer empty upon IPR update, or in subsequent frames if rendering multiple frames within single process. |

20.5.572 | Karma will now properly update in IPR when a displacement shader references a COP texture. This requires "Continuous Dicing" to be enabled. |

20.5.571 | Added a parameter to the ROP Fetch and ROP Geometry TOP nodes that controls whether distributed sim trackers are managed using hostnames or IP addresses. |

20.5.571 | There were optimizations made to texture evaluation on machines with large numbers of cores (esp. with NUMA architecture). |

20.5.570 | The work item script or command line string can now be overriden per-node, using an override parameter in the "Schedulers" tab. |

20.5.570 | Fixed an issue that could cause Houdini to crash rendering subd meshes in the viewport with Vulkan. |

20.5.569 | Updated the ZibraVDBForHoudini SideFX Labs plugin to v1.0.3.0. This fixed a crash encountered when decompressing empty grids. |

20.5.569 | Fixed a bug in Spiral shelf tool that prevented it from handling the Z-up viewport preference correctly. |

20.5.566 | Add new HOM `hou.hda` methods to `installFiles`, `uninstallFiles` and `reloadFiles` to operate on a list of file paths as a batch. The batch operation will defer the implicit "dsreload" call until the end of the batch operation. When an OPLibraries file is loaded (like when loading a .hip file) the "dsreload" call is deferred until the end, instead of after each HDA file. |

20.5.566 | Fixed a bug on the fktransform component where the color is not set when using the shapecolor propery. |

20.5.566 | Updated the ZibraVDBForHoudini SideFX Labs plugin to v1.0.2.0. Summary of changes outlined here: https://github.com/ZibraAI/ZibraVDBForHoudini/releases/tag/v1.0.2.0 |
Fri. April 11, 2025 |
![]() |
20.5.566 | Fixed crashes in the MotionClip Extract Key Poses and MotionClip Pose Delete SOPs when the input motion clip geometry did not contain any primitives. |

20.5.566 | Fixed a bug where changing point instance count from zero to non-zero would cause karma to fail to update. |
Fri. April 11, 2025 |

20.5.566 | Fixed issue where shelf tool hotkey actions would not have proper labels and help when introduced by a keymap file under the new hotkey system. |
Fri. April 11, 2025 |
![]() |
20.5.566 | Improved persistence of dynamically added hotkey symbols and bindings across switching keymaps. Fixed issue where, after switching to a keymap, any bindings from that keymap to shelf tool hotkeys not yet explicitly registered in the current session by Houdini would not work. |

20.5.565 | The SOP Cache Manager will no longer try to unload SOPs that are currently cooking, that could result in crashes with memory culling enabled. |

20.5.565 | When LOPs is checking for the existence of a layer (such as implementing the "Handle Missing Files" parameter on a Sublayer or Geo Clip Sequence LOP), the layer would actually be opened which validated not only its existence, but that it was a valid USD file. But this could have a large performance impact, so now we only check that the file exists. This will result in a change in behavior in the case of existing but invalid files. |

20.5.565 | LOP nodes with a "Handle Missing Files" parameter set to detect an alert about missing files used to direct the USD library to open the layer file. This could be quite expensive for some file formats like BGEO. Now Houdini just checks for the existence of the file. This is much faster, but will no longer detect invalid files (only truly missing files). |

20.5.564 | Fixed a bug in the Agent Pose from Rig SOP where incorrect transforms could be assigned to the agent if the target skeleton had non-default scale inheritance modes. |
