    Hi, As far as I understand the "Dissolve" Photoshop blend mode works something like this:
    Is a shader for available somewhere? Or would you point me to a GSLS shader I could adapt? Thanks!

      i dont know how relevant this is for shaders... but for image blend modes in apps like PS you would first create a 2-bit random map (with even distribution) across the canvas (0 0 0 and 255 255 255), then modify that by multiplying it pixel by pixel with the opacity delta between the layers (alpha foreground - alpha background)
