Hi everyone,

I have a doubt. Recently I needed to make an animation of a cable, which have both ends connected to another object. I have everything animated in Blender, but when I imported it in Houdini I was not able to parent the end of the cable to the empty/null/geometry.

So I created a very basic setup that could work for a similar purpose. We have a cylinder and an animated sphere mesh. Then we group the intersecting points and add them to a pin target in vellum. That works, but when I animate the sphere, I can not make those points to follow it, how would you make it?

Attached is the setup.

Thanks in advance
