Hi everyone,
I’m using the command "r.Tonemapper.Sharpen x " to reach the render i need for my scene and when i’m using the high res screenshot tools the screenshots appear without sharpen modification.
If someone have a solution or an explanation to fix this problem it will be very helpfull !
thanks for your answers et have a nice day ! 
PS : i’ve already try to use an another way to make screenshots with nvidia ansel but it seems to be a bigger problem at the end … (impossible to make it work after 3 days of researches on the net …)
