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 17.0.299 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'.

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 17.0.274 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.
