Ok ; some of blend here exist but i found some others only on photoshop.
I decided to compile all of 20 photoshop blend in one file. The author is credited in this shader;
*screen, mult, overlay, hardlight, softlight, color(Dodge/Burn), linear(Dodge/Burn), vividLight, linearLight, pinLight, hardMix, subs, div, add, diff, darken, lighten, inv, invRGB, hue, sat, col, lum, blend.
If you want one of them i will make only one blend shader per request. The fx number is for that.
Live demo: crazy music is from me .. when i was musician remixing Claws/zooming.mod..
