Brighten on Diffuse Maps at Once?

[AbeTJH]

I have a Multi-Suboject material of a plant whose leaves are all too dark. Instead of going in one by one in each material, adding a color correction and brightening the gamma manually, is there a way I can apply the same settings to all materials at once? See attached setup.

You can use modifier modifier ZORB to do mass changes to anything so also the RGB level of bitmaps or gamma of VrayHDRIs or similar. or might want to try scripting and try and change this script a bit to your purpose: https://forums.chaosgroup.com/forum/...ction-map-slot
