Language Setting: Language: Controls the display language of HDA parameters. Currently, Chinese and English are available. Since this is a global modification, newly created instances of the HDA will follow the selected language option. If switching languages within Unreal Engine, you must select the language and then click the Rebuild button for the changes to take effect. It is not recommended to modify the language while Houdini and Unreal Engine are both open.
Curvature: If enabled, the bookshelf will have a curved shape.
Curvature Ratio: When the curvature option is selected, this value controls the overall curvature strength of the bookshelf. The range is 0.01–0.7, and the final curvature effect depends on the total length of the bookshelf.
Length: Controls the total length of the bookshelf.
Shelf Height: The height of each shelf level. It should be adjusted in combination with the length for an optimal display.
Number of Shelves: Controls the number of levels in the bookshelf, determining its overall height.
Panel Thickness: Controls the thickness of the top and bottom panels, as well as the back and side panels of the bookshelf. The thickness should ideally be slightly greater than the divider panels but not excessively thick.
Base: If enabled, a base will be added to the bottom.
Base Type: Three types of bases are available:
Number of Dividers: Controls the number of vertical dividers per shelf. More dividers result in more compartments.
Divider Thickness: Controls the thickness of the dividers.
Arrangement Mode: Determines the layout of the dividers.
