Unite Berlin 2018 - Editor Scripting the Scene View
Editor scripting is Unity's most advanced dark magic. You can create build scripts, custom inspector windows and your own productivity tools. However, you can also create editor tools that work right in the scene view: Visualizing important design data when you need it, adding handles to create visual editing capabilities and even completely custom level design tools that fit your game. Learn how to supercharge your design tools right in the Scene View.
