Houdini Main Changelogs

Houdini 17.0.431 Unity plugin: Heightfield layers sharing the same "tile" attribute value in a Geo node will be created as a single Unity terrain with corresponding layers. This allows an object merge containing multiple heightfield layers to be grouped properly by tile index when creating Unity terrain with layers. yesterday
Houdini 17.0.431 A bug has been fixed that could possibly cause non-deterministic repellant behaviour in a whitewater simulation. yesterday
Houdini 17.0.431 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. yesterday
