So the 74 shaders we got in r100 are totally awesome and so forth (no, really, I've been messing with them for like 2 hours straight ^^;) but there is no color replace shader as seen in CC. There were 6 paramaters; old RGB and new RGB. It was perfect for changing certain colors on a sprite, and palette shifting (think NES Megaman / NES Megaman charging).
Is anyone else in need of / willing to write such a shader?
(To my knowledge "set color" is the closest effect so far, but it affects the entire sprite. Cloning the sprite numerous times, erasing 1 color each, stacking them, and applying the set color effect seems to be the only option right now, but that's pretty inefficient.)
Also, the Image Manipulator object in CC allowed you to retrieve the RGB value of a point on an image. Like if the color was solid blue on the x,y coordinates (5,10) it would return 0,0,255. It was great for using actual palette images instead of entering the RGB values by hand. Is that possible in C2? I haven't really kept up with the 3rd party plugins so..
