Houdini Main Changelogs

Fix Object Merge SOP bug where if multiple node references were entered into the same Object N parameter, only the last specified node would correctly register as a name interest. This meant that prior paths would not get updated on the parameter if the referenced nodes were renamed.

19.0.591

Fixed crash on Linux distro's using glibc version 2.34 or later (eg. Ubuntu/Pop_OS 21.10, Fedora 35, CentOS Stream 9, etc) resulting from libcurl using both jemalloc and libc malloc.

Due to the new dicing behaviour that reduces gaps between diced grids, renders with subd or displacement may produce different looking results.

Thu. April 14, 2022

All but eliminated dicing gaps and cracks from displacement and subdivision. Dicing Flatness property is deprecated and hidden.

Thu. April 14, 2022

Fixed a bug where resuming from checkpoint may fail if the render has deep image output enabled and the number of threads is different from the original render's that produced the checkpoint file.

Thu. April 14, 2022
19.0.590

Removed excessive ray bias on a partially opaque material when the shading point is far from origin. This reduces the likelyhood of continuing rays to miss surfaces that are in close proximity.

Thu. April 14, 2022
19.0.590

The SOP Character Import LOP no longer errors out if the source skeleton is missing the 'clipinfo' attribute. The scene frame range is used as a fallback, matching the behaviour of many other KineFX operators.
