As far as I understand, photometrics are handled terribly in VW for lights that zoom. Please tell me if I'm missing something here.
A light is able to have a beam angle and a field angle. (It can also have both in a perpendicular axis, i.e. for PARs)
There is nothing in a light that references zoom range, so what I'm seeing most people do is put the Narrow Zoom Beam Angle in for "Beam Angle" and the Wide Zoom Field Angle in for "Field Angle".
Is this the best approach? Or should it be Narrow Zoom Field Angle for "Beam Angle"?
How does Candela respond to zoom range? As I understand it candela is a unit correlated to beam angle of the output.
So what Candela value am I supposed to put into the symbol of a light that zooms? Let's say I put the narrow zoom candela value in... then if I go to do photometric layouts it is going to be all wonky.
It seems like the answer is LIR needs Beam1 / Beam 2 / Field 1 / Field 2 / Candela -- NARROW as well as Beam 1 / Beam 2 / Field 1 / Field 2 / Candela -- WIDE. Then it needs a zoom slider thingy that adjusts those values in a proportionate relationship. No?
