Houdini 18.5.688 For SideFX internal use only: Backport r396530 Wed. September 1, 2021
Houdini 18.5.688 Fixed a PDG bug where running simulation jobs on a Tractor farm failed because the simulation tracker prematurely terminated. Wed. September 1, 2021
Houdini 18.5.688 Fixed a possible crashing bug when rendering instances with a relatively large number of transform motion segments. Wed. September 1, 2021
Houdini 18.5.688 Fixed an issue with ROP Fetch service workers exiting unexpectedly, if the target ROP node failed to cook. Wed. September 1, 2021

Houdini 18.5.687 Fixed an issue where karma would sometimes have issues resolveing UDIM textures with the .tex file extension. Tue. August 31, 2021
Houdini 18.5.687 When an input mesh has a multi-material applied, the plugin will now create a detail attribute named "hemax_material" that stores the name of the multi-material. The names of the sub-materials will continue to be stored in the "hemax_material" primitive attribute. Tue. August 31, 2021
Houdini 18.5.687 Added the Copy Property LOP that copies attributes from one prim to another, or from one name to another on the same prim. Provide tab menu tools to convert light primitives to/from the new attribute names introduced in USD 21.02, so that Houdini (which uses USD 20.08) can load USD and accurately display files authored with newer USD libraries. Tue. August 31, 2021
Houdini 18.5.687 Fixed a bug with the minimal pyro solver not working when Global Substeps were increased beyond 1. Tue. August 31, 2021

Houdini 18.5.686 Fixed a bug with the minimal pyro solver using timescale to calculate source frame numbers. This bug resulted in different outputs when switching out of minimal mode. Handling of timescale should now be consistent across different modes of the pyro solver. Mon. August 30, 2021
Houdini 18.5.683 Added the sidefx::maya_parm_syncs_asset parm tag. This tag notifies Maya that a full asset sync should be performed when the parm is modified. Fri. August 27, 2021
Houdini 18.5.683 The Geometry Import TOP will no longer throw an error when the node is dynamic and configured to import data from a SOP node. Fri. August 27, 2021
