Houdini 18.5.618 Fix bug in the ROP FBX Character Output where it would fail to export the requested rest transform value for rigid shapes. In addition to this, it would also output an additional key at frame 0 which is no longer done. Wed. June 23, 2021

Houdini 18.5.618 Fixed an issue that could potentially cause slow performance if computing normals was required when merging many small pieces of geometry. Wed. June 23, 2021
Houdini 18.5.617 Node Option defaults are now configurable from the Options menu. Tue. June 22, 2021
Houdini 18.5.617 Fixed an issue with the linux version of the Unity plugin missing important autogenerated files. Tue. June 22, 2021
Houdini 18.5.617 Added a new agentchannelcount() VEX function which returns the number of channels in an agent's rig. This is similar to the agenttransformcount() function for accessing the number of rig transforms. Tue. June 22, 2021
Houdini 18.5.617 Batches will now wait for the first non-cached frame to be ready, rather than just the first frame. This avoids a race condition where an input frame at the end of the batch is not cached, but the batch cooks from cache anyway. Tue. June 22, 2021
Houdini 18.5.616 Fix ROP FBX Character Output SOP crash when exporting bad path/name/blendshape_name attribute combos that results in trying to export a shape that has no geometry. Mon. June 21, 2021
Houdini 18.5.616 Added a Neighbor Group parameter to POP Steer Separate, which specifies the points that are considered when searching for nearby agents. Mon. June 21, 2021
Houdini 18.5.616 Fix crash when the Pose Space Deform SOP is given a second input that has non-packed primitives. Mon. June 21, 2021
Houdini 18.5.616 Fix Bone Capture Lines SOP bug when given only point influences. It would internally use an infinite fuse tolerance that resulted in only a single output point. Mon. June 21, 2021

Houdini 18.5.616 Fix issue in Unpack SOP where the varmap attribute within the packed details would be erroneously promoted to be primitive attribute instead of staying as a detail attribute (thereby preventing its actual usage).

This also fixes the FBX import issue from the File SOP when importing multiple shapes at once could result in the varmap attribute showing up as a primitive attribute instead of as a detail attribute.

Houdini 18.5.616 Fixed potential null pointer dereference in the viewport menu. Mon. June 21, 2021
Houdini 18.5.613 Made it safe to call HUSDinitialize more than once, so HDK initialization code can safely call this function if necessary. Fri. June 18, 2021
Houdini 18.5.613 Fixed an issue with sporadic canceling of batch work items, when cooking with First Frame is Ready with cached inputs. Fri. June 18, 2021
Houdini 18.5.612 Fix issue in the ROP FBX Character Output SOP where it did not handle blendshapes that were not Packed Geometry primitives. Thu. June 17, 2021
Houdini 18.5.612 Remesh 2.0 output may be altered on (1) inputs with primitive group not equal to all polygons, (2) those that have boundary edges, or (3) those with explicitly specified hardened edges. Thu. June 17, 2021
Houdini 18.5.612 Fixed a bug in Remesh 2.0 which caused degenerate triangles around boundaries and hardended edges. Thu. June 17, 2021
Houdini 18.5.612 The USD Import TOP now has an option to copy input files to work item outputs, if the USD data is specified using an upstream file or custom path. Thu. June 17, 2021
Houdini 18.5.612 Fixed a bug in Remesh where nongroup polygons were always triangulated. Thu. June 17, 2021
Houdini 18.5.612 Fixed an issue where SOP meshes with a namespace operator (::) wouldn't bake properly due to an illegal filename. Thu. June 17, 2021
Houdini 18.5.612 Fixed an issue with hkey/sesictrl not returning licenses when using a custom port for sesinetd. Thu. June 17, 2021
