Hello to all, I found another annoying issue about ToneMap control shaders applied to a physical material to the background...
Below what happen with and without tone map control into the material...(without tone map you need to adjust camera exposure settings)
here the c4d scene:

[EDIT] seems to be the "ACES" that give this strange square splotch on the background...if you disable it the problem is gone...
