Fixed a bug in the TopoBuild state that prevented it from working correctly in multiple views.

Fixed bug rebuilding asset when obj visibility was changed in asset

Fixed bug with cooking after loading a level with instanced inputs

Added rotation and pscale attribute to curve inputs created by an unreal spline component. Fixed multiple issues when modifying world outliner inputs after loading from file.

Added some special case handling to the PolyExpand2D SOP that can substantially improve cooking time in certain degenerate cases. Also improved warning messages that might be added during the cook to give more information.

Parsing of group fields no longer errors out if there are trailing spaces.

Fixed crash rendering particle system primitives when some points have pscale of zero.

Fixed a bug where the Sculpt SOP, and possibly some other cases of brush-based SOPs, were only keeping the last "dab" in each stroke. The issue that caused the Sculpt SOP to fail was introduced recently when trying to fix the same sort of problem for other brush-based SOPs. HDK code using SOP_BrushBase or GU_Brush may need to be recompiled.

You can now change the radius of the Group Paint SOP brush in the UV viewport.

Disabled threaded flattening of procedruals by default. This may lead to a small increase in start-up time, but is significantly more stable when rendering large scenes. This should help with rendering stability overall.

Fixed a bug in the Bullet Solver that incorrectly put inactive objects to sleep.

fixed switching input types is broken when cooking on parameter change option is disabled in the details panel.

Fixed bug with BakeTexture ROP when using displacement (Ds) output type (zero values for hi > low res objects).

Fixed a crash in Houdini that sometimes occurred when opening parameter menus defined by custom PARMmenu.xml files. The crash was related to menu items that had a <context><expression> field.

File Cache SOP Render With Take menu now properly linked.

Volume VOP SOPs using from camera that live inside SOP Solvers no longer crash.

Add ability to finish a PolySplit with shift-RMB

Viewport: Remove Backfaces no longer makes particles visualized as points disappear.

Fixed PolySplit's group creation behaviour. If the group specified already exists, it now replaces that group instead of giving an error. A parameter "Append to Group" has been added to append the new edges to the group instead of replacing it entirely.

Fixed a couple of bugs in the PolyExpand2D SOP that could cause bad results during the straight skeleton contruction in rare cases.

Fixed memory leak in the PolyExpand2D SOP.

Fixed Houdini crashing when PolySplit is given split locations in the form pa-b where a and b are points on the geometry. PolySplit will give an error if the given points are not connected.

Exposed scale parameter on Pxr area lights (rectangle, disk, and sphere).
