This allows Photoshop like curves in ENB. Preview: http://cubic-bezier.com/#.17,.67,.83,.67
I used parts of code from Prod80 and Ceejay.dk in this but it has mostly been rewritten. Thought ill mention it anyways.
Also i am still a noob with Shaders so feel free to correct me if i did something wrong.
i made this code with Sandvich Makers Macros viewtopic.php?f=6&t=5961
So you will need that or youll need to rewrite the UI on your own. This however allows you to also Let these work in DNI or else without mutch work (just change the "UI_FLOAT" to "UI_FLOAT_DNI")
so here the UI:
Code: Select all
#include "Reforged/ReforgedUI.fxh"

UI_MESSAGE(1, "1 = Darken, 2 = Multiply")
UI_MESSAGE(2, "3 = Linearburn, 4 = Colorburn")
UI_MESSAGE(3, "5 = Lighten, 6 = Screen")
UI_MESSAGE(4, "7 = Colordodge, 8 = Lineardodge")
UI_MESSAGE(5, "9 = Overlay, 10 = Softlight")
UI_MESSAGE(6, "11 = Vividlight, 12 = Linearlight")
UI_MESSAGE(7, "13 = Pinlight, 0 = Bypass")
