Hello,
I am very new to unreal engine and I am struggeling with the following problem:
I want to add a feature which extracts the luminance values of a whole scene and saves them in some file similar like it is done in the “Visualize HDR” view mode. In this view you can query the luminance values of the scene only in a small area of the scene.
I also want to add it to a camera actor as a postprocessing step.
Can someone help me out if something like that is possible and can provide some starting point how I can begin developing?
Thanks a lot in advance!
