Something like a light-sensor?

Hi.
I’m working on a 3D map of an apartament, in which I can place different light-sources (of various intensity) to model the real situation.
I would need to know exactly the instensity of the light in a certain point of the floor, to make some calculus about propagation.
I have thought about this solution, but I don’t know if it’s realizable. Pratically I would need something that (positionated on the floor) measures the light in that point and write it somewhere.
Is it possible to do something like that?
Thanks.

but i’v head that indigo renderer can emulate reel lamps fixture
this would allow you to calculate the illuminance in lumen of footcandel on the working plane
if you understand what i mean

but i don’t know anything that measure light inside 3D soft or renderer!

Salutations

Ok, I will try to find another solution.
Thank you :slight_smile:
