Is there a list explaining what each node in the material editor actually does?

Hi guys i was wondering whether there is a list explaining what each node means/does. For example im analyzing the subway ue4 scene and ive noticed a 'cei’l node and i have no clue what it does. And even just for simple nodes such as multiply etc it’d be nice to have a written definition so to speak.

God i am, then! :smiley:

Nah, i’m just a mortal noob helping other noobs. :stuck_out_tongue:

Jacky you are a goddess or if you’re of the male orientation your a god, thank you!
