    Hello. I’m very new and very green in expressions, but i want to lear this beuty =)
    I need to find x and y position of red pixel that comes from png or tga image layer “image with alpha background”.
    It is possible to do with expression? And if who knows, please help and write me ready to go example.

    I hear that to do this need to use sampleImage.
