Alt click on a node connection automatically disconnect it from the other nodes. And there is some nodes which can be easily summoned by pressing a key and clicking at the same time. Like B+click will place a branch, and S+click a sequence.

The massive artbook with all the sketches used during the production of Fallout 4 is already available for preorder in the official Bethesda shop. This edition is pretty expensive ($50) at the original Bethesda Store but it’s definitely worth the investment, since you’ll get a whole bunch of images from some of the best artists in the world, including Istvan Pely (who also wrote a foreword to this edition), Adam Adamowicz, Ray Lederer, Ilya Nazarov, and John Gravato. There will be pictures of environments, characters, detailed weapons illustrations plus the commentary from the developers. And you can buy it on Amazon for just $28!
Each artist has a unique visual style, and together they drafted a rich and varied world, with every design having personality and authenticity. Our process is very iterative: we start with loose, rough sketches, which are gradually refined into detailed drawings that are then handed off to our 3-D artists. And even after a model is built and textured, we often revisit and rework that model until it achieves a level of quality we can be proud to ship. In these pages, we try to show a variety of images from all stages of this process. As you can see, we carefully consider every detail of the game, sometimes to an obsessive level; this is pretty much the Bethesda way.
While the focus of this book is on art, the amount of work done by professionals across multiple disciplines at the studio cannot be overstated. Designers give the work purpose and context; programmers ensure that everything works smoothly. Animators give it life, while audio engineers give it voice. And producers make sure all of these parts come together efficiently. Without all of this effort, the images you see here would have never left the page. To witness the amount of passion and talent that goes into this process is truly humbling.
I hope this book gives you some sense of what it’s like to see a world materialize around you from scratch. It truly is an amazing thing to experience and a privilege to be a part of.
