The Pixel Lab posts an introductory look into using Spline Dynamics in Cinema 4D. Joren Kandel shows how you can set up cables, ropes, and other elements that can make use of C4D’s dynamics system.
Used Spline Dynamics before? Joren offers some tips for managing them in your scene. The model used in the demonstration is from the Pixel Lab’s Events and Venues Pack you can find in the store here: thepixellab.net/products.
If you want to dive into more materials that works with dynamics, a while back, Cinema 4D Artist Benjamin Ring showed how you can use splines to create a winding rope. Another one is CG Trainer CyBear , posts a look into scripting complex dynamic interactions in Cinema 4D.
