This is a crowd behavior node, but you can also use it on regular particles (see the Output attribute parameter).
When this is off, the node will have no effect. You can animate this to turn the behavior on or off at different times.
Only modify a certain group or groups out of all agents/particles. You can name groups of agents using the Group name parameter on the Crowd Source geometry node.
Available when Output attribute is “Crowd steerforce”. This number is used by the crowd solver to normalize and scale multiple forces that apply to an agent.
Strength of the cohesion force.
Use Field of View
When this is on, each agent only considers other agents it can “see” in front of it (within Field of view degrees around its forward direction) with the Search radius distance. When this is off, each agent considers all other agents within the Search radius, regardless of their relative position.
Field of View
When Use field of view is on, the angle of the field of view (in degrees) around the agent’s forward direction. The agent will only consider agents inside the field of view and the Search radius.
Only consider other agents within this distance (in meters).
