Sorry to hear about confusion in this thread. I still use the same techniques for shading and node network construction as I did in these lessons, so I’m not quite sure where the disconnect is happening. One thing I will say is that the information to learn is not the exact values I plug in. Rather the concept of how to tweak the values is what I hope you learn.
In practice, I don’t memorize certain values for the mapping node. But I understand how the node works and thus how to go about tweaking the values to my needs. I think that’s why the nodes seem to function the way they always have to me, even if the underlying math was changed.
Does this make sense?
