/Signal_Names or /SIGNAL_NAMES The names of the signals used by the Pipeline Command.
The + symbol is used as a delimiter for multiple entries.
For example, to specify the three signals RFT1, RFT2, and RFT3
/Signal_Names=RFT1+RFT2+RFT3 Many commands allow Signal_Names to be blank
/Signal_Names= In the cases that this is allowed, this indicates that Visual3D should use all signals of the specified Signal_Types
