Added support for Houdini box and sphere native types to be automatically converted to Unity box and sphere colliders if their group name is set to collision_geo or rendered_collision_geo. This support for box and sphere types can be disabled in Plugin Settings -> Cook Options.

Fixed major bug with saved assets in scene when the scene is reloaded in a new session and the asset has to be cooked again. Bug was causing state information to be lost due to not accounting for object names to change between sessions for SOP assets.

Fixed Rebuild Asset not reapplying asset preset (parameter vaulues, input, etc).

Major rework of how Houdini heightfields are converted to Unity terrains. Fixed issues with heightfield sizes causing padding issues. Now anything power of 2 plus 1 and grid spacing of 2 should work fine. Fixed heightfield tile splits so they are imported and aligned properly. Fixed output terrain being positioned wrong on some imports, and on baked outputs. Added support for layers other than just height. These other layers are applied as Terrain alphamaps. These are now exposed to a new Terrain section on the asset UI, allowing user to set textures and other material settings. Also exposed is a strength parameter allowing to apply a multiplier on the layer's values before submitting as alphamap. A default Terrain splat texture is used for layer textures and the default can be changed in the Plugin settings. Fixed duplication null error with heightfield assets. Fixed multiple heightfield objects within same subnet not working properly.

Input nodes now always have Keep World Transform enabled by default, which is the correct behaviour and consistent with other Engine plugins. Fixed input nodes losing their objects in saved scenes due to not finding inactive or project-specific objects.

Reset Parameters will now properly reset input nodes.
