.1

The trace is laid in one pass on the system’s first frame, and the count is the straight-line distance from the firer to the far end of the beam multiplied by this figure and truncated. Distance is in leptons, 256 to a cell, so .1 puts about 26 particles in every cell the beam crosses and a shot across five cells lays around 128 of them. Only the Railgun behavior reads it.

SpiralDeltaPerCoord=.03

The particles are spread evenly along the beam whatever the count, so the figure controls the trace’s density rather than its length: a low value leaves a dotted corkscrew and a high one a solid rope. At zero or below no particle is laid at all, and the system does nothing but draw the beam Laser=yes asks for and retire.
