TECHNICAL PAPER Building Tools for Houdini 9

Componentsand lighting will have to come from other lights in the scene. The only real purpose of this is to makesure something reasonable happens if the user tries to render the simulation.Tool ScriptsOptionsName: rbd_simpleLabel: RBD: SimpleTool Shelf Behaviour- Tool works on any geometry object selection in the viewport. It also works with no selections.- Takes selected object and references its display geometry to create DOPs RBD Objects.- If less than 3 objects are selected, the user is prompted to make additional object selections.These are optional- If a valid selection is made when tool script is completed, the tool is created with those objectsreferenced.- If the user chooses not to make a selection when tool script is completed, the simulation is createdwith default geometry – a torus, a sphere, and a teapot, piled into a stack.Tab Menu Behaviour Viewer PaneViewer Pane Mask(s): OBJ- Viewport is placed at the object level if it’s not there already to add RBD Simple.- Upon selecting the tool, the user is queried to make one or more selections. Upon completionof the selection(s), the tool is created with those objects referenced as new DOPs RBDObjects.Tab Menu Behaviour Network PaneNetwork Pane Mask(s): OBJ- Network pane must be an object network to add RBD Simple. It is not available to any othercontexts.- Upon selecting the tool, the RBD Simple asset is added to the network. The user is then expectedto reference the appropriate geometry objects if desired. The user can do this by drag ‘n’drop into the object parameter fields of the RBD Simple asset parameter pane.Asset ScriptsNoneAsset(s)Rbd_simple- Single HDA that contains a SOP network and a DOP network.Shader(s)SurfaceAssign generic Mantra shader to extracted SOP geometry.DisplacementN.A.ProceduralN.A.Sourced DataNoneGenerated Data26 | TECHNICAL PAPER Rev 1.0
