This is a 3ds Max tutorial that David Fano has tuned into a video from a PDF written by Theo Calvin and Omer Barr. Using wire parameters and expression controllers in 3D Studio Max we will make a panel that opens and closes based on the distance of a point. Learn how to model in 3ds Max with wire parameters and expression controllers. It will help if you are already familiar with the 3ds Max interface for this tutorial. Create an expression driven panel in 3ds Max.
