But you can already do that!? What else do you want? There are already exposure and burn values in the VFB and you can save a .cube file out in the latest two SPs.
And a more advanced color mapping would be the Filmic tonemapping(implemented the same way as described above) which I’ve been banging on about for quite some time :)Which of the three or four different flavors of filmic tone mapping do you have in mind?
Best regards,
