Houdini Main Changelogs
| 22.0.451 | Fixed a harmless "GLD_TXTURE_INDEX_2D is unloadable" Apple OpenGL warning that occurred at Houdini startup on macOS. |
yesterday | |
| 21.0.847 | Persist the "Disable color correction" toggle in the color editor across sessions. |
yesterday | |
| 22.0.451 |
|
yesterday | |
| 22.0.451 | Improved the speed of the APEX Animate state when scrubbing the playbar. |
yesterday | |
| 22.0.451 | Fixed a bug with hserver where it was caching dynamic discoverd settings like DNS server settings which caused hserver to stay on that sticked setting instead of discovering the new value. |
yesterday | |
| 22.0.451 | Fixed a bug in the UV Flatten from Points SOP that could result in a crash after a cook failure. |
yesterday | |
| 22.0.451 | HUSD_PointInstancer::copyUsdAttrsToGeoAttrs now takes an additional 'is_time_varying' paramater to track whether or not the SOP needs to be marked as Time Dependent. HUSD_PointInstancerSampleData::accumulate was also updated to use HUSD_ProtoResolution to help track prototype information, such as resolved prototype index from string matching, etc. |
yesterday | |
| 22.0.451 | Fixed issues with the Insert Quick Material menu in the Material Linker LOP. |
yesterday | |
| 22.0.451 | Fixed a faulty warning message, which was displayed in the log when running ML Train Gsplats, where it claimed it couldn't find the image path. Functionally nothing changed. |
yesterday | |
| 22.0.451 | Fixed a bug in the Neural Layer to Mask (SAM2) COP, where toggling on proxy mode caused the node to error as it was expecting fixed 1024x1024 input size. |
yesterday | |
| 22.0.450 | Fixed a bug where the geometry inputs for a modifier HDA were always being disabled and greyed out. Now only the first input will be disabled because it is reserved for the object that the modifier is applied to. |
Mon. September 21, 2026 | |
| 22.0.450 | Fixed the Houdini PyImath libraries so that they have a custom "_sidefx" suffix in their library names. This helps avoid conflicts with system PyImath libraries. |
Mon. September 21, 2026 | |
| 22.0.450 | Fixed an issue with hkey where preferences required a restart. |
Mon. September 21, 2026 | |
| 22.0.450 | Unify the use of the term "Data Set" in parameter labels of ML Train Neural Cellular Automata and ML Preprocess/Train GSplats TOP nodes replacing the previous "Dataset". |
Mon. September 21, 2026 | |
| 22.0.450 | Added clearer error message to ML Train Gsplats logs, when detecting GPU architectures incompatible with installed PyTorch or CUDA versions. |
Mon. September 21, 2026 | |
| 22.0.450 | Fixed a case where Cage Ray Directions were producing suboptimal bake results in certain cases on Bake Pre-Process COP and SOP. |
Mon. September 21, 2026 | |
| 22.0.450 | Fixed a bug in the glTF importer where it mapped the specular color factor in materials to generic 1,2,3 channel names instead of the Houdini r,g,b color channel names. |
Mon. September 21, 2026 | |
| 22.0.450 | Fixed a critical bug on Bake Geometry Textures COP where tangent normal frame was constructed using Cage Normals, not Low Resolution Normals. This will fix previous errors in the tangent normal map. |
Mon. September 21, 2026 | |
| 22.0.450 | Fixed a bug in the glTF importer where it mapped the specular color factor in materials to generic 1,2,3 channel names instead of the Houdini r,g,b color channel names. |
Mon. September 21, 2026 | |
| 22.0.450 | Introduced new parameters for controls over the Ray Directions on the Cage Mesh on Bake-Pre Process COP and SOP, which by default sets their directions to their topological match on the Low-Resolution. |
Mon. September 21, 2026 | |
| 22.0.450 | Fixed a bug where ML Train Gsplats failed when running on multi-GPU linux systems. |
Mon. September 21, 2026 | |
| 22.0.450 | Added support for the glTF diffuse alpha, occlusion texture strength and normal texture scale material properties to the Mtlx glTF Material. |
Mon. September 21, 2026 | |
| 22.0.450 | Refactored ML Train Neural Cellular Automata TOP hutil training scripts; no user-facing behavior change. |
Mon. September 21, 2026 | |
| 22.0.450 | Backported doc update - Edit LOP's edit-retargeting instructions and removed unused parm details. |
Mon. September 21, 2026 | |
| 22.0.450 | Backported updates for RFE 156531 Added files for Re-target Transforms pane in Edit LOP. Updates to enable Re-target Transforms pane in Edit LOP Added button delete edits with incorrect paths Added button to remove all unused edits Removed refresh button and added a callback to refresh when delta parm is edited Added undos for all ops |
