Determines if the creation frame refers to global Houdini frames ($F) or to simulation specific frames ($SF). The latter is affected by the offset time and scale time at the DOP network level.

The frame number on which the object will be created. The object is created only when the current frame number is equal to this parameter value. This means the DOP Network must evaluate a timestep at the specified frame, or the object will not be created.

For example, if this value is set to 3.5, the Timestep parameter of the DOP Network must be changed to 1/(2*$FPS) to ensure the DOP Network has a timestep at frame 3.5.

Instead of making a single object, you can create a number of identical objects. You can set each object’s parameters individually by using the $OBJID expression.

The name for the created object. This is the name that shows up in the details view, and is used to reference this object externally.

When turned on, newly created objects are solved by the solver on the timestep in which it was created.

This parameter is usually turned on if this node is creating objects in the middle of a simulation rather than creating objects for the initial state of the simulation.

By preventing a large object from being cached, you can ensure there is enough room in the cache for the previous frames of its collision geometry.

This option should only be set when you are working with a very large sim. It is much better just to use a larger memory cache if possible.

Starting geometry for the Vellum simulation. This represents the display or collision geometry.

Usually new objects are created using the Vellum Source DOP, this is most useful when restarting an existing simulation.

NOTE: You may need to use a POP Stream node to re-home the initial geometry in the new DOP network. If the initial geometry “stops working” after adding additional sources, this is likely necessary.

Whether to display the geometry in the viewport.

Starting constraint geometry for the Vellum simulation. This represents the constraints between points of the display geometry. It should have a one-to-one point correspondence with the display geometry.

Usually new objects are created using the Vellum Source DOP, this is most useful when restarting an existing simulation.

Whether to display the constraint geometry in the viewport. Usually constraints are displayed using the guides instead of showing the raw geometry.

Whether to display guide geometry in the viewport.

Forces the guide geometry to draw as wireframe.
