Houdini Main Changelogs
|Houdini 17.5.106||Unity plugin: Added support for setting terrain layer properties such as textures, shader values, tile size, and tile offset via primitive attributes on heighfield. This also includes the new TerrainLayer properties in Unity 2018.3. These layer properties are exposed in the HDA's UI for terrain, and can be overridden by user, similar to other parameters. The attribute names have been added to the online plugin documentation under the Attributes section.||Thu. December 13, 2018|
|Houdini 17.5.98||Unity plugin: Added PDG HAPI imports.||Wed. December 5, 2018|
|Houdini 17.5.97||Unity plugin: Added support for specifying multiple input HDAs for object merge path parameter. Previously only one HDA was allowed. HDA inputs also now expose and support the Keep World Transform and Packed Primitive options that regular mesh inputs had. Fixed bug where loading preset with inputs objects that weren't root objects in scene failed.||Tue. December 4, 2018|
|Houdini 17.4.70||Unity plugin: Fix for terrain and other generated outputs transforms being offset.||Wed. November 7, 2018|
|Houdini 17.4.1||Unity Plugin Version 2: Fix for generating large number of instances. Fix HEU_ParameterAccessor RequiresUpload=true when setting input.||Thu. August 30, 2018|
|Houdini 17.0.319||Unity Plugin Version 2: Fixed transform handle not working in certain cases.||Thu. August 23, 2018|
|Houdini 17.0.311||Unity Plugin Version 2: Now using unique file name for debug hip file, instead of always using the same temporary file name. Disabled parameters are now disabled in Unity HDA Parameter UI.||Wed. August 15, 2018|
|Houdini 17.0.311||Unity Plugin Version 2: Now checks 32-bit Windows registry entry for Houdini and Houdini Engine installation location. Fix for Substance error on Unity 2018.1+ Updated docs with troubleshooting info when Houdini not found or session isn't created.||Wed. August 15, 2018|
|Houdini 17.0.306||Unity Plugin Version 2: Now removing empty output properly. Also fixed removing outputs that on previous cooks had valid geometry, but no longer. Removed rebuild / recook buttons being disabled while cooking due to exceptions causing them to stay stuck sometimes.||Fri. August 10, 2018|
|Houdini 17.0.305||Unity Plugin Version 2: Rebuild Asset will now save asset preset, then reload it after rebuilding the asset. This keeps parameter and input values. Save and Load Preset now support input nodes. All input node data will be saved and then attempted to be loaded back in, if still found in scene. Gameobjects are saved as just name references, therefore if they are not in scene when loading back in, they are ignored. Added tooltips for asset options.||Thu. August 9, 2018|
|Houdini 17.0.305||Unity Plugin Version 2: Fixed Substance warning on Unity 2017.4.||Thu. August 9, 2018|
|Houdini 17.0.304||Unity Plugin Version 2: Fixed input meshes being uploaded into Houdini from Unity as disconnected polygons.||Wed. August 8, 2018|
|Houdini 17.0.303||Unity Plugin Version 2: Fixed input assets in saved scenes not keeping correct object path references in Houdini. Updated docs with info on updating plugin.||Tue. August 7, 2018|
|Houdini 17.0.299||Unity Plugin Version 2: Fixed crash in Unity when using large input geometry with materials.||Fri. August 3, 2018|
|Houdini 17.0.299||Unity Plugin Version 2: Now supporting embedded materials used in input geometry. Unity treats these as subassets, part of the main container asset. Plugin adds a SUBASSET:: tag to the material path attribute in the input geometry and on the roundtrip back, does the special subasset load if material path has this tag. Fixes using OBJ files with embedded materials in input nodes.||Fri. August 3, 2018|
|Houdini 17.0.296||Unity Plugin Version 2: Added support for setting Unity layer via primitive or detail string attribute with name 'unity_layer'. Moved setting of tag, layer, and scripts for output gameobjects after all geometry and instances have been generated. Updated Attribute section in docs.||Tue. July 31, 2018|
|Houdini 17.0.289||Unity Plugin Version 2: Added support for packed primitives with groups. This allows for instanced meshes with collider and LOD groups. Fixed collider mesh not generating without a renderable mesh. Now if an output has a collider mesh specified but no renderable mesh, the collider mesh will still be generated and applied to the GameObject.||Tue. July 24, 2018|
|Houdini 17.0.284||Unity Plugin Version 2: Added UI lockout to the HDA_Data gameobject to prevent user tampering. Disabled the Transform Offset on an input node if its Keep World Transform is unchecked. Transform Offset does not do anything if Keep World Transform is not enabled. Some general house keeping.||Thu. July 19, 2018|
|Houdini 17.0.283||Unity Plugin Version 2: Now setting visibility on children of instanced gameobjects which gets hierarchical LOD instances working correctly.||Wed. July 18, 2018|

|Houdini 17.0.275||Unity Plugin Version 2: Added Save HDA Preset and Load HDA Preset to Asset Options UI. These allow the asset's parameter preset to be saved to a file, and loaded from a file. The preset file can be used to clone HDA parameters across scenes and projects, as well as managed by source control. Added info to docs as well.||Tue. July 10, 2018|
|Houdini 17.0.274||Unity Plugin Version 2: Checking changed parameters for cooking asset after Undo. Previously it would just update all parameters but this can cause buttons to trigger.||Mon. July 9, 2018|
|Houdini 17.0.274|| Unity Plugin Version 2: Recook Asset will now only update changed parameters before cooking. Previously it was uploading all parameters resulting in buttons being invoked on Recook Asset.
Added new Reset Parameters button which allows to reset the asset's parameters, input nodes, and curve modifications.
Changed Reload Asset to Rebuild Asset button name, to be consistent with the UE4 plugin. Functionalty it stays the same.
Updated online docs to reflect the above changes.
