Houdini 22.0 Nodes APEX nodes

TimeStep

Creates an input node with a port to get the current time step.

Since 22.0

This node is an alias for an Input node with a port whose value is set to the current time step. The time step is the amount of time that passes between each frame. It is defined in terms of the frames per second (FPS) (timestep = 1.0/FPS), so you must adjust the FPS to change the time step. The FPS can be modified using the Global Animation Options.

The port’s value (the current time step) is automatically set by an APEX scene whenever the scene is evaluated - when the animate state is active on an APEX Scene Animate SOP, or when the scene is being evaluated by an APEX Scene Invoke SOP. The current time step is intended to be used by character rigs.

By default, the port name for the current time step is TIMESTEP. You can modify this port name by setting the timestep_input detail property on the graph (using an Attribute Adjust Dictionary SOP, for example). If the timestep_input property already exists on the graph, the newly-added Input node’s port name will be set to this property.
