thanks for your reply here are the screenshots. My output is not matching with the tutorials whereas I'm following the exact values.1st image from tutorial second is mine. Any idea and world machine is a complicated.
Experiment with each of the nodes, helps to learn what they do. Agree with what musashidan said. If you're following a tutorial to the letter, you're missing the point. Tutes are merely an intro to something. Probably the best way to follow a tutorial is to stop now and then and putter around, try all the buttons out.
