How to connect spring to two object?

[Carl Allinson]

Hi all,

I’ve been having a play in C4D, creating the Pixar lamp. The design has springs and I’m wanting to know how to connect the spring to two objects that work with an IK rig.

I tried using Xpresso to connect the spring helix height to the objects position, which works; however when i use the controller for the IK rig, it decides not to.

I have the spring dynamics activated and it allows me to target object A and B and the preview works like a charm. Is there a way to use that preview information to apply to my spring?

Thanks
