Hi!

I have a question about the raytracer export, more specifically the physical unit of the pixel values in the exported EXR files.

I exported an EXR file, and I see values from around 0.0-3.0 there, based on that I would guess that it contains Luminance values.

However the docs say its "illuminance distribution". My understanding is that Illuminance value of a pixel would be calculated by multiplying the luminance value with the solid angle of the pixel, but that would result in way smaller values.

Does someone have some insight into this?

Thanks in advance!
