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.

More comments for UT_JSONParser and UT_JSONWriter.

XPU: fixed a PDF bug in BSDF code. As a result users may notice a faint increase in brightness with glossy surfaces.

Fixed a bug where applying displacement on a mesh with constant or uniform normal attributes would lead to a crash. This bug was introduced in 19.0.590.

Fixes a bug in the sweep2.0 sop where swapping rows and columns causes a crash when end caps are specified that the cross section curve is open.

Fixes a bug in the rig pose viewer state which would cause a python exception to repeatedly be thrown during playback while a volatile view state was active and a joint was selected.

Introduces a new option to hserver (--option-file-location) that prints the location of the option file and will suggest a location for the options file if the option file does not already exist.

Fixed a bug where husk would not send the houdini:frame and houdini:fps render settings to the render delegate when rendering with a USD render settings prim.

• Fixed Unreal Spline Component's closed state being incorrectly set when using world input.
• Fixed world input ignoring the "Use Legacy Curve" setting when sending unreal spline components.The setting was only used for (Houdini) curve inputs.
• Enabled the "Use Legacy Curve" setting by default as it helps with instabilities when inputting curves/splines.

Include the start time of hserver when reporting hserver information.

The SOP Import LOP now propagates error messages from the referenced SOP node.

The Volume Mix SOP is now able to mix vector VDBs with other vector VDBs. As a result, vector velocity VBDs can now be interpolated by the Retime SOP.

• Fixed a bug that caused UploadTransformToHoudini to only work when

CookOnTransformChange was enabled.

• Houdini Proxy Meshes are now enabled by default.

Improve hwebserver and the help servers handling of archive files.

Fixed security bug with hwebserver and the help server able to access files outside of the root directory.

Fixed a bug that caused empty array attributes to have an incorrect HAPI_AttributeInfo::storage value.

Fixed possible crash when dicing elongated polygons. This bug was introduced in 19.0.590.

Second attempt at fixing crash on Linux distro's using glibc 2.34 or later.

In version 19.0.556 we added support for detecting the color space for 16-bit png files. In this, there was a bug that single channel .png files could be interpreted as being in sRGB color space. This is no longer the case.

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.

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

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.

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.

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.
