Following this tutorial: https://www.youtube.com/watch?v=fdWUjEMzDhg (4:40) I have reached the part that I want to add color to the liquid but in the shading nod editor panel the elements are not connected as much as I try. Am I missing something? Someone help me please. BTW it can't be connected in the compositing panel either.
I made a video with my issue: https://www.youtube.com/watch?v=9gAA5VdOR3g&feature=youtu.be
