Houdini 18.5.546 When evaluating a parameter without an active work item, PDG nodes will now default to using the time value that was set when the TOP network began to cook.

When a parameter is evaluated against a particular work item, the work item's frame value is still always used to determine the evaluation time. Mon. April 12, 2021

Houdini 18.5.543 Added an option to the Crowd Trigger's raycast mode to use the agent's orientation to determine the ray direction rather than the agent's velocity. This can work better for stationary agents or for locomotion where the agent's velocity is in a different direction than where the agent is facing. Fri. April 9, 2021
