[Unreal Engine 5.5] [Lighting][luminance]
I am working on a projekt to simulate real lighting in Unreal Engine.
Therefore i need realworld photometric values in it. I can give the Lightsource real values with IES-files but i cannot figure out how to measure the light effects on objects.
For this i want to create a luminancemap of my scene where every pixel gehts the luminance value and is displyed in false colors. I can create a post process material that creates a false color display but i cannot link it to real luminacne values in cd/m^2.
In the picture you can see what i want to create but as stated before i cannot get correct values.
Is there a way to extract correct luminance values for every pixel from the engine?
In this forum and the internet i could not find any solution for this… and even in the marketplace there is not a single asset that could handle this…
I would really apreciate if someone would know how to solve this.
Does not matter if c++ oder blueprint.
