Title: linking light to intensity
Post by: mraw on 2015-07-02, 12:47:36

Honestly I do not know if this makes sense to you: I like to play with the shape of a corona light(rectangle for example) in order to find the nicest look(e.g. in reflections)
For this I wouldn't want the brightness to be changed. For me it would be a great feature to have the option to link size and intensity.
So if I change the size of my rectangle light, the intensity would be changed accordingly that the overall amount of emitted light stays the same.

It is perfectly possible now. Just change intensity units from default to say lumens and you'll get what you want.

Has this changed in 1.3?
If I change the size of the light now, the intensity(lumen) doesn't change.
It still works, but the intensity value doesn't change anymore. Is this a bug or on purpose? thanks.

No, it's not bug and it worked like that from the begining. Lumen output doesn't dependant from physical light size.

I remembered that the intensity value changed(maybe Candela?) during dragging the size sliders. Obviously I'm wrong. Sorry.

I only use Lumens, easiest way to recreate physically correct lights.

can you recommend a resource about Lumen, Lux, Candela?
