Houdini Main Changelogs

Houdini 18.0.539 The primuv() VEX function will now properly interpolate attributes in 64-bit mode. In particular, this affected lense shaders as they run in 64-bit mode by default. Wed. July 29, 2020
Houdini 18.0.538 Fixed an issue in HQueue where the SQLite backend file indefinitely grew in size. Tue. July 28, 2020
Houdini 18.0.538 Significantly improved the performance of job deletion in HQueue. Tue. July 28, 2020
Houdini 18.0.538 Add Convert Units parameter to FBX Filmbox ROP/SOP. When enabled, it will export by first converting to centimeters from the Houdini system units. It defaults to off so that it matches the old behaviour and the FBX scene importer (so that we can round trip via defaults). Tue. July 28, 2020
Houdini 18.0.538 Hardened HoudiniGL against USD attributes that have incorrect lengths for their class. Tue. July 28, 2020
Houdini 18.0.538 Exposed the pdg.AttributeFile.valueForTag and pdg.AttributeFile.valuesForTag methods in the PDG Python API. Tue. July 28, 2020
Houdini 18.0.538 Hide the LOP stage if within a child object or SOP network in LOPs. Those networks embedded within a LOP node will still display the stage (eg. SOP Create and SOP Modify). Tue. July 28, 2020

Houdini 18.0.537 Fixes several performance regressions. Extra connections to the license server were being created instead of reusing the already existing connection when possible. Mon. July 27, 2020
Houdini 18.0.537 Fixes bug when getting the local ip address two different functions were used. This caused the license diagnostic to not always report the ip address that was actually used while licensing. Mon. July 27, 2020
Houdini 18.0.537 Updated ROP USD Top to refresh the parms that are referenced by the contained USD ROP node. Mon. July 27, 2020
Houdini 18.0.537 Added support for querying array attributes in HAPI. New functions have the syntax `HAPI_GetAttribute*ArrayData`. Added totalArrayElements to HAPI_AttributeInfo which stores the total number of entries in an array attribute (since array attributes vary in size per entry). Bumped HAPI version. Mon. July 27, 2020

Houdini 18.0.534 Fixes bug where hostnames had to match case which in most cases caused a license loop. This is incorrect as case should be ignored. Fri. July 24, 2020
Houdini 18.0.533 When the network cooked by a ROP Geometry Output, ROP USD Output, etc is modified, the work items in the TOP node will now have their cache files invalidated. This means that the work items will recook even if existing files are found on disk, unless the cache mode is set to Read Files. Thu. July 23, 2020
