Input Standard copies regular particle properties such as position, speed, scale, etc., from the current particle system. The parameters are the same as the Input Proxy suboperator, except that there are no Proxy System Indexing controls.
Also, Input Standard allows for an additional property:
Bear in mind that each Display and Render operator has its own Visible % parameter. That parameter is independent one, and has nothing to do with the Visibility property from a Data operator. The standard Display and Render operators obey Visibility data control from a Data operator. Display Data and Display Script also obey the Visibility data control.
