and some of my learning material were based on 18 or early 19,
since I'm using 19.5 indie,
I don't know whether there are difference by versions,
or those nodes are simply disabled and cannot use anymore?

by the way,
why is my looks so different than the source?

How can I settle this so my nodes will be exactly the same as the tutorials?
Thanks in advance.
