Hallo all,

I'm trying to get a physical value out of the irradiance map (blendluxcore 2.6).
Are the values is W/m²?
And how can I convert to lux?

The values of the irradiance path are changing if I alter the color temprature, but I can't find the right conversion to lux...

Can you give me a hint?

:? Doesn't it depend on settings as mentioned in Irradiance Contour?

As far as I can see it does not ...
I will run some more tests and come back with a more precise question ...
