I found this value that is a perfect for what I am trying to achieve in my project, so I was wondering how I were to retrieve it in blueprints or C++, but I am completely stuck on how to actually retrieve it. I can preview the illuminance values in SkyLight when the show illuminance meter is ticked in visualization. I was able to see that it’s calculated in reflectionenvironmentshaders.usf, and is also used in illuminancemeter.cpp, but how to access or use those those files is outside of my C++ knowledge.
The value from the material node SkyAtmosphereViewLuminance is also alternatively a value I can use, in which I am also clueless in how to actually transfer to blueprints as I’m only able to see its value by projecting its value to a plane in the world by using the DebugScalarValues node.
