Let's say we have a string of bi-directional light points with 4 points.
And they all have the same direction and a front color of red. All but one
have a back color of red as well. The odd ball light has a back color of
white. Like so:
FRONT | red | red | red | red
-------------------------------
BACK | red | red | red | white
Performer cannot have a bidirectional light with different colors. So we
want to make opposing pairs of unidirectional lights to simulated this,
where neccesary.
The performance question is:
Would it be better to make 1 bidirectional pfLightPoint for the 3 red
lights, plus 2 unidirectional pfLightPoints (1 red and 1 white)?
OR
Would it be better to make 1 unidirectional pfLightPoint for the 4 red
lights, plus 1 unidirectional pfLightPoint for the 3 red and 1 white light?
Basically, which is more efficient: 3 pfLightPoints of 5 lights, or 2
pfLightPoints of 8 lights? Also ... consider the trade-off on a much larger
scale. Right now I'm leaning towards more lights per pfLightPoint.
