Houdini Main Changelogs

Houdini 15.5.654 Fixed a bug with ray:hitPs (for getting around terminator artifacts) in trace function, which could cause blocky shadowing artifacts. Note that this removes self-shadowing that were sometimes erroneous, and might lead to results that are slightly brighter (notably with glossy materials). Thu. November 10, 2016

Houdini 15.5.654
  • Fixed instabilities and issues when mesh distance field generation is activated.
  • Added a project setting to cook curves only on mouse release.
  • Added settings (project and per asset) to choose the distance field resolution scale used on generated static meshes.
  • Fixed "Rebuild Asset" not working properly if parameters order were changed.

Houdini 15.5.654 Fixed a crash which would very very rarely occur when computing memory used by channel expressions. Thu. November 10, 2016
Houdini 15.5.654 Improved the Crowd State DOP's clip randomization parameters. Clips can now be randomly selected from a list of clip names/patterns and weights. Thu. November 10, 2016
Houdini 15.5.654 Fixed the orientation of RIS lights (disk, etc) Thu. November 10, 2016
Houdini 15.5.653 Fixed instanced geometry being invisible during PIE. Also fixed undo of overriding instanced geometry with and Actor asset. Wed. November 9, 2016
Houdini 15.5.651 Unreal: The Navigation system was using cached geometry from the Static mesh to handle collision for the NavMesh. Because of this, the NavMesh was always using the first geometry created by an asset for the Navigation System collisions. The navigation collisions are now rebuilt after modifying the asset, and the NavMesh updated properly so that it uses the proper collisions. Mon. November 7, 2016
Houdini 15.5.651 Fixed a bug where the help browser could not open on newer Linux OS versions because of SSL errors. Mon. November 7, 2016
Houdini 15.5.651 The fetch object will no longer render a point when rendering in mantra or other renderers. Mon. November 7, 2016
Houdini 15.5.651 Fixed a deadlocking issue introduced in 15.5.650 with the optimized performance in mantra's displacement shading. This deadlock could also affect VEX geometry functions and other parts of Houdini. Mon. November 7, 2016
Houdini 15.5.650 The size of the UT_TaskExclusive object has changed. This breaks the ABI for any classes that have a UT_TaskExclusive as member data. Currently, none of uses of this are exposed in the HDK, but any custom code using UT_TaskExclusive will need to be visited. Sun. November 6, 2016
Houdini 15.5.650 Optimized threaded performance when mantra does displacement shading. There was an change introduced in 15.5.625 which exposed a thread contention issue. Performance is now improved. Sun. November 6, 2016
Houdini 15.5.647 The start frame parameter on the Test Simulation: Crowd Transition DOP now defaults to $FSTART instead of 1. Thu. November 3, 2016
Houdini 15.5.647 Restore the ability to create HDAs from Shop Subnetworks. Thu. November 3, 2016
Houdini 15.5.646 Fixed bug where @elemnum in the Attribute Wrangle SOP and the Geometry Wrangle DOP was sometimes incorrect for vertices and primitives. Wed. November 2, 2016
Houdini 15.5.645 unreal: fixed a bug preventing assets from being duplicated/copied, loosing selection instead. Tue. November 1, 2016
Houdini 15.5.644 Houdini no longer outputs "UT_NetPacket::read: No error" when killing the Mantra process. Mon. October 31, 2016
Houdini 15.5.644 Fixed agent rendering in the OpenGL ROP. Mon. October 31, 2016
Houdini 15.5.642 Renaming a scene level style sheet no longer does a global search and replace of the old name for the new name throughout the hip file. This was useful in a small number of cases, and potentially very harmful in other cases. The opchange hscript command can be used to replicate this functionality if it is needed. Sat. October 29, 2016
Houdini 15.5.641 Improved performance of rendering with material style sheets that have embedded material definitions with inline VEX code. Fri. October 28, 2016
Houdini 15.5.641 Fixed an issue where the Bullet solver did not ignore constraints for which both anchors were attached to the same rigid body (which includes objects that are glued together). This issue could produce unexpected or unstable results. Fri. October 28, 2016
Houdini 15.5.641 Added light filter object nodes for RenderMan RIS. Fri. October 28, 2016
Houdini 15.5.641 Unreal: Added support for instancing of arbitrary game assets via point and detail attributes, as well as via instance overrides. Fri. October 28, 2016
Houdini 15.5.639 When setting the up vector to the terrain normal is enabled, the crowd solver now adjusts the orientation immediately on the first frame instead of being limited by the max turn rate. This makes it easier to set up the initial state of the agents for such simulations. Wed. October 26, 2016
