I have a couple of questions about the new Area Light Spread setting as I am incorporating it into the Physical Lights units of my Photographer addon.
The spread value conserves energy, meaning using a narrower spread will focus the beam and make it brighter. However, this is not how the Spotlight Size (cone angle) works, does it make sense to have two different behaviors? I see that you wanted to give the option but it’s not what has been committed at the moment.
I will support both depending if it’s lumen or candela anyway, but I am curious about this choice.
Spread is not supported by EEVEE and breaks compatibility between the two engines now, especially because of the brightness difference. Will it be added before 2.93 release?
