Part 4 of the Verge3D Tutorial - Interactive Parametric Model is an optional deep dive into the puzzle detail for the remaining slider controls. There are some unique decisions when it comes to the StepDown sliders that may be useful to know as you head in to Part 5.
This tutorial was created at the request of a Verge3D user Omrto from the Verge3d forums. Videos 2 through 5 are recorded live as I work through the process and work through the bugs and issues in real-time. Follow along and watch me go through the process of creating problems, fixing bugs and getting this to work.
