Hi developers UE4 .
I have difficulty to learn node UE4 (Material_Editor , Blueprint) .
In the help I could not find a description of each node.
Please make a comfortably help similar Houdini 
For example, you select a node in the node configuration press button help
Hey Artem_Tema -
I will pass along your request to our documentation team, but I also want you to know that many nodes have additional information available to them if you hover over them and hold CTRL-ALT.
Thank You
