hello to all !
i have a question concerning the image based simulation where i am using 2 ceiling lights and a simple room of 4 walls and no windows. i am trying to change the brightness and the intensity of the light sources by adjusting the “Candela multiplier” as shown in the picture below
according to the changes made to the " Candela multiplier " , the grid based illuminance values look logic and its constantly changing with the changes of the multiplier values.
but my problem is with the image based simulation, whenever i make changes for the “Candela multiplier” i cant seem to witness any changes of the light brightness and intensity in the output picture. even when the illuminance is nearly 0 lux, the render doesnt show any darker light and the room still looks the same.
can someone please help me out with a small explanation on this ? and how can i manipulate the brightness of the light to have darker space in the final image
I wonder if this has something to do with the candela multiplier not getting updated in the rad file definition. Can you share your gh file?
(It might be a day or two before I can get to this)
I couldn’t run your gh file as it contained too many components that werent present in my Grasshopper installation. Anyway, I recreated the relevant part of your simulation in a different gh file. At least on my side there doesn’t appear to be a problem: With candelaMultiplier at 1
