Hello,

I'm new to Black Ink, and I'd like to learn how to use the controllers. I watched the tutorial videos, yet I just can't understand how does it all work . Can somebody please explain it to me? Thanks in advance

Good question !

Controllers allow to “program” a brush’s behavior using blocks.
The block system was made with a single output to ease its use and so that users don’t get lost by the node/link paradigm usually seen in 3D modeling software.

There is already a video tutorial explaining usage of the Controller system available here.
Your question, though, asks for a more detailed answer, and a new video tutorial that would explain thoroughly the way it works is a very good idea indeed !
