AGX Experiment
29/09/2023
This is an experiment in replacing Filmic display mapping used in UE5 with AGX display mapping proposed by Troy James Sobotka[1].
AGX preserve details in both dark and bright areas and keeps saturation levels to a much more manageable range (no over saturation in dark or bright areas) and to me it feels much more natural and closer to what I see with my own eyes compared to UE5 exaggerated filmic look.
I don't say UE5 filmic is bad or incorrect though (I do like it in some ways) but I think I really like AGX more and I'm pretty sure that will definitely do more experiment with it and use it in my future projects.
Note that these images where obtained by modifying the HLSL code of the engine but then I discovered (just before postiong this) that UE had a OpenColorIO plugin so more on that later.
Everything is rendered with UE 5.0.1.
