Changed HAPI_ThriftServerOptions::timeoutMs default from 3000 to 30000.

VEX warnings and errors generated by warning() and error() in SOPs will no longer have an extra "Vex error:" but just report the error directly, saving space an avoiding confusion when warnings are reported as errors.

Fixed a warning in the IPR pickpixel.py script, which triggered by ctrl+ left clicking on a pixel in the IPR window.

Fix Channel SOP crash when trying to load into unsupported array attributes.

Added support for 3ds Max 2025.

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.

Fixed a crash when the Layer Replace LOP tries to replace a sublayer on the stage root layer.

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.

Fixed a crash when the Layer Replace LOP tries to replace a sublayer on the stage root layer.

Fixed a bug where the launcher would not clear the task bar progress indicator when an install had finished.

Fixed a bug with the dirty and cook (shift+v) operation having no effect on a TOP subnetwork with node errors.

Fixed bugs where the Edit SOP did not apply the falloff for an attribute distance metric when the soft radius was 0.

Fixed a bug where modifying displacement shader parameter may fail to redice object in IPR. This bug was introduced in 20.0.666.

Fixed a bug where mostly opaque surface could sometimes prevent rays from continue tracing against the rest of the scene, which could manifest as holes in the alpha channel.

Added a method hou.SceneViewer.resetViewportCamera which is the equivalent of the "Reset Native Viewport Camera" entry in the viewport camera menu.

Fixed a bug where N AOV would erroneously output geometry normals when the mesh has uniform/per-primitive normals.

Fixed an issue with the File Decompress TOP failing to cook when used with input work items that produce archive files while cooking.

Fixed an issue with TOP graph static cooks attempting to trigger cooks for TOP nodes that haven't been initialized yet.

Add a "Delete Item" action to the right click menu of selection sets in the APEX Animate State when right clicking on any item inside of a selection set. This gives an easy way to remove controls from sets without first needing to select them, which is necessary for controls that have been removed from the scene or are otherwise invalid.

Added a new Log Command: Houdini.DumpGenericAttribute This can be used to list all properties/generic attributes for a given class, listing the expected unreal_uproperty_XXX attribute names and types, and if the system supports it. Usage example: Houdini.DumpGenericAttribute StaticMesh

Houdini will now use the HOUDINI_PATHMAP file when loading the OCIO configuration file.

Fixed an issue with the USD Import TOP incorrectly saving floating point data as integer work item attributes.

Fixed 'Scene Import' mode on the Component Output LOP.

Fixed an issue where invalid agent blendshapes (e.g. using a channel name which does not exist) caused all blendshapes to be skipped. This also affected other nodes such as the SOP Character Import LOP.

Fixed sampling parms for the Sky light on Karma Physical Sky.
