Houdini Main Changelogs
19.5.961 | Fixed a crash that could occur when opening the network editor list view for a VOP Network with a Parameter VOP set to "Export: Always". |
Wed. April 24, 2024 | |
19.5.956 | Fixed an issue where nested prim patterns were not properly propagating time-varying status from child to parent. |
Fri. April 19, 2024 | |
19.5.956 | Added a %foreach auto-collection that runs a sub-pattern for each prim that matches a primary pattern. |
Fri. April 19, 2024 | |
19.5.955 | Fixed a potential crash in Edit Material Network LOP when loading shaders. |
Thu. April 18, 2024 | |
19.5.953 | Fixed an issue with custom tags not working correctly with ROP Fetch TOP. Output files were always using the first tag in the custom tag list, instead of the tag that matches the corresponding output parameter. |
Tue. April 16, 2024 | |
19.5.953 | Fixed a crash when the Layer Replace LOP tries to replace a sublayer on the stage root layer. |
Tue. April 16, 2024 | |
19.5.953 | When a relationship from a USD API schema is added as a parameter to an Edit Properties LOP, setting the relationship now applies the API schema, as was already happening for attributes from API schemas. |
Tue. April 16, 2024 | |
19.5.946 | Added environment variable (HOUDINI_NO_EXTERNAL_ICON_CACHE) that can be used to disable external icon caches to aid in debugging cache problems. |
Tue. April 9, 2024 | |
19.5.945 | Fixed a bug where Du/Dv VEX calls may sometimes return garbage when the input parameter is a uniform value. |
Mon. April 8, 2024 | |
19.5.945 | Fixed a crash that could occur while opening a hip file if a context option change callback changes another context option's value. |
Mon. April 8, 2024 | |
19.5.939 | Fixed hanging in Houdini related to Python SOP nodes. For example, Houdini would hang when cooking Python SOP nodes from Houdini Engine Session Sync, or when a background thread tried to call into HOM while Houdini cooked Python SOP nodes. The fix required restoring old behavior in Python SOP nodes that unfortunately reintroduces an old hang, one at least that is limited in scope. The old hang occurs when Python SOP nodes execute multi-threaded code that calls into the HOM `hou` package from separate threads. If you wish to run such code in Python SOPs, then you can set `HOUDINI_ALLOW_PYTHON_SOP_MULTITHREADING=1` in the environment with the caveat that you may encounter other hangs as detailed above (i.e. cooking Python SOP nodes from Session Sync). |

19.5.934 | Fixed a bug where volumes straddling camera's far clip plane could sometimes cause render to hang. |
Thu. March 28, 2024 | |
19.5.933 | Fixed a bug in the Trace SOP that resulted in stretched results when using a volume wider than it is tall. |
Wed. March 27, 2024 | |
