Lighting - adjust intensity/attenuation to multiple lights via percentage

I’ve been doing a lot of mass adjustment of lighting in my project recently. Of course it’s possible to select multiple lights at the same time, but when the values (intensity/attenuation/radius/length etc) for the lights differ, the only option is to change them all to one specific value.

My suggestion is when multiple lights are selected, all these values to be adjusted via a relative percentage increase/decrease.

Take this example :-

  • Light 1

  • Intensity - 100

  • Attenuation - 500

  • Light 2

  • Intensity 200

  • Attenuation - 1000

A relative increase of these lights by 50% would give me

  • Light 1

  • Intensity - 150

  • Attenuation - 750

  • Light 2

  • Intensity 300

  • Attenuation - 1500

The same could apply to source radius and source length.

It would just make adjusting multiple lights a bit easier when the values differ. Just curious as to whether implementing something like this would be feasible.

Cheers.

Came across this many years later while googling how to do this. Guess it’s not as easy as hoped!
