To get an accurate reading of the illuminance in your level you need to measure it on a surface that’s perpendicular to the sun. We already have can setup a couple of planes set up for this purpose so then all you need to then do is set r_HDRdebug  1 in the console and simply look at the surface. Keep in mind that turning this on brightens the whole scene so don’t forget to turn it off once you’re done measuring your illuminance.


This section contains all the different parameters that control the sun rays effect. The only one we will be changing for this particular scenario is the Sun rays attenuation.

Sun rays visibility

This value controls the visibility of sun rays. Higher values cause brighter rays around the sun.
