TutsGFX has released a five part video training series on scripting in Vizrt Artist. Each video concentrates on a different script to manipulate your scenes. The videos go a little further than just writing the script but also explains the theory behind the code and shows you where to access various resources to use in writing your scripts. After watching the videos you will be able to apply the knowledge gained to write your own scripts. You can watch the videos here.
Scripting inside of a scene can be a powerful way to manipulate and add functionality to your designs. Pretty much anything can be accomplished through scripting if you can write the correct functions in the editor. There are two ways or places to add a script within a Vizrt Scene. You can do it in the background scene settings having the script affect the scene globally or you can add the script function plugin which can affect a local container. Though scripting in Vizrt Artist can get quite in depth, these videos give you the fundamentals behind the language and allow you to develop your programming skills further. If you are familiar with programming languages then scripting in viz will be familiar to you. Keep in mind that this scripting is different from writing action in action key frames.
