Hello
For the beta V4
I have downloaded the Pentakis... familly nodes inside the last Max Smirnov
November nodeeditor.v.0.97.2017.10.05.zip + New EditorCss + Editor.js

I have "red nodes"

What is the method for make these nodes efficient ?
Does it possible ?
Or I must load a // Elephant (What is its last version ? And it's working in the beta V4)
