Houdini Main Changelogs

Houdini 18.5.733 Fixed a bug in the Smooth 2.0 SOP that could result in a crash when the input geometry contains unconnected points. yesterday
Houdini 18.5.732 The hou.Geometry.intersect methods will now always internally normalize the ray direction. The resulting point will thus match the 18.0 behaviour for un-normalized behaviour. This does mean that the min/max parameters will be in world space, not the ray-space. Fri. October 15, 2021
Houdini 18.5.732 Houdini to Unreal StaticMesh translation: fixed an issue where duplicate warnings would be logged in Unreal for meshes with invalid face / vertex data, for each index that is invalid. Fri. October 15, 2021
Houdini 18.5.732 Ensuring the Boolean SOP copies detail attributes from input geometrie(s). Common detail attributes will be set to values from first input. Fri. October 15, 2021
Houdini 18.5.732 Updating the EULA to version 2021-10-13. Fri. October 15, 2021
Houdini 18.5.731 Version 2:
  • Fix issue where HDA would fail to produce output if HDA is a Sop/Subnet with display flag set on an output node and Use Output Nodes is enabled.
Thu. October 14, 2021
Houdini 18.5.731 Version 2:
  • Added support for the unreal_bake_name attribute that can be used to set the name of the object(s) generated during baking. The unreal_output_name attribute takes precedence.
  • When baking Houdini Instanced Actor Components the unreal_output_name (or unreal_bake_name) attribute, if set, is now used to determine the baked instance actor names.
  • When baking Houdini Instanced Actor Components the instanced object name is now used as the default bake name instead of the HDA actor's name (if the unreal_output_name and unreal_bake_name attributes are not set).
  • Houdini Instanced Actor Components now support the unreal_bake_actor attribute when baking: the instanced actors are attached to unreal_bake_actor (which is created as an empty actor or re-used from a previous bake depending on the replacement mode).
Thu. October 14, 2021
Houdini 18.5.731 Version 2:
  • Fix unreal_landscape_editlayer_target attribute for Landscape Modify mode.
  • Fix landscape input targeting using Input0, Input1, etc.
  • Fix Landscape edit layer transforms in Modify mode.
Thu. October 14, 2021
Houdini 18.5.731 Fixed a bug where the viewer would not be properly updated to show the current node after switching from something like a Chopnet node. Thu. October 14, 2021
Houdini 18.5.730 Fixing a bug in detection of similar islands for stacking may affect the results when this option is used. Wed. October 13, 2021
Houdini 18.5.730 Fixing a bug in UV Layout 3.0 SOP which sometimes failed to identify similar islands for stacking due to nearly collapsed UV edgs, e.g. in quads where one of the edges has almost (but not exactly) zero-length. In certain cases this could lead to very long search times, effectively hanging Houdini. Wed. October 13, 2021
Houdini 18.5.730 Fixed an issue where viewport ladders reset to 0 after the cursor reached edge of screen. Wed. October 13, 2021
Houdini 18.5.730 Fixed the Color COP so that custom planes are generated with the correct color. Wed. October 13, 2021
Houdini 18.5.729 Fixed bug where the viewer would be missing an interest in the current SOP if it was not also the display SOP after the viewer switched from the view state to the current SOP's state. Tue. October 12, 2021
Houdini 18.5.727 Fixed an issue where LOP networks would unnecessarily recook after Save As. Sun. October 10, 2021
Houdini 18.5.724 The fixed bugs in PolyBevel 3.0 and the increased animatability may in some cases break backward compatibility. This was not observed in our own regression tests as the changes engange on in somewhat extreme situations. Thu. October 7, 2021
Houdini 18.5.724 Fixing a number of bugs (mainly crashes in special cases in PolyBevel 3.0). In addition, this revision improves the smooth transition of offsetting and the round fillet curves providing smoother animatability. Note however that PolyBevel does not guarantee animatability in all cases. Thu. October 7, 2021
Houdini 18.5.724 Fixed a visual bug with environment lighting in normal quality lighting when a material had a diffuse texture. Thu. October 7, 2021
Houdini 18.5.724 Fixed several issues with using stylesheets to override custom user properties and then generating a cryptomatte layer from the user property. Thu. October 7, 2021
Houdini 18.5.723 Fixing a number of bugs in Measure SOP 2.0.

Most importantly: 1. A new toggle is added to allow the per-piece accumulation combine pieces that were previously refined due to lack of connectivity or non-manifold edges.

2. Handling of pre-existing attributes is improved with some issues regarding addition to the pre-existing values for the "total" attributes or clearing of non-group values is addressed.

Wed. October 6, 2021
Houdini 18.5.723 Update sesinetd default log level options to reflect the previous versions default values. Wed. October 6, 2021
Houdini 18.5.722 Fixed bug that caused the log entry for successful checkouts to log as level 5 instead of the default log level 2. Tue. October 5, 2021
Houdini 18.5.722 Version 2:
  • It is now possible to set the default directory used in the browse dialog for File parameters by using the "default_dir" Parameter tag.
  • Fixed a crash when trying to assign object path properties via generic attributes with an invalid path.
Tue. October 5, 2021
Houdini 18.5.722 Fixed bug in the Type Properties dialog where folders were incorrectly ignored when updating conditional strings after creating new parameters by dragging nodes or folders or using the From Nodes tree. Tue. October 5, 2021
Houdini 18.5.722 Fixed an issue where instancers with no valid instances would be kept, creating unnecessary gameObjects. Tue. October 5, 2021
