Fixed a bug where the SOP Create LOP wasn't assigning materials properly for imported volumes.

The File Rename TOP now supports renaming upstream output files, instead of always requiring a custom file path.

Fixed an issue where the Bullet solver did not correctly import box primitives that had a mirrored transform. This led to various stability issues in the simulation.

In DOP Import 2.0, the Geometry Data Path parameter can now specify a pattern or list of subdata paths, rather than just a single path. Optionally, an output attribute can also be added to identify the subdata path that the geometry was imported from.

The File Rename TOP no longer requires an input node.

Fixed a bug where editing a layout brush would often have its changes stepped on.

Fixed a bug in the Pose Library where it failed to save and load animation clip data stored on disk.

Fixed missing geometry in the viewport when inside a SOP Create/Modify LOP and the display flag was set to a different SOP.

Added the imageio 2.6.1 Python package to Houdini. Also added imageio's dependencies, enum34 1.1.10 and futures 3.3.0, to Houdini but only for the Python 2 build.

Fixed a bug in the Pose Library where it failed to generate animated thumbnails when capturing a clip.

Added per-curve weight attribute support to the Volume Velocity from Curves SOP.

The Shift+R hotkey in the network editor will now rotate input connections on all selected nodes, not just the current node.

Fixed selection picking of volumes in the LOPs view.

There's a new karma global rendering property to enable/disable image blur.

Both the ffmpeg and imagemgick job scripts can now be configured to run in-process. The ffmpeg and imagemagick exectuables themselves still execute in their own process.

The POP Steer Obstacle DOP now includes the obstacle geometry (when imported from SOPs or a context input) in its guide geometry, in addition to the agent spheres.

Fixed an issue where baking terrain outputs using output nodes would result in an error

Fixed a bug with instancing assets where assets were not always loaded from disk when not in memory.

Version 2: Only set Landscape layer NoWeightBlend option if a LayerInfo is created for the first time or if an attribute is present.

The Agent Collision Layer SOP now allows the bounds scale of each shape to be overridden.

PDG attributes access from Python now have a new `isArray` property, which is set to `True` for datatypes that support arrays of values (int, float, string and file).

Fixed a case where an animated texture would sometimes not update properly in the viewport.

Added an option to SOP Import to control whether the attribute name is added as a prefix to the subsets produced from string partition attributes.

Updated USD library with some custom additions that make Houdini's viewport much faster when displaying large numbers of native instances. Also added a new API that can be used by render delegates to improve memory use in scenes with many point instancer primitives using instanceable primitives.

Enabled the selection of point instancer instances when using render delegates besides Houdini GL. Also made some performance improvements in native instance selection and scene graph tree refreshes.
