1. I have made a rope using a string of vertices and added the cloth modifier to it.
2. I pinned one end so that the rope swings.
3. I duplicated the string of vertices and converted them to a curve.
4. Then I added hooks to each vert on the curve.
5. Then I parented the hooks to the verts on the rope (the original string of verts).
6. Added a bevel depth and resolution to the curve.
When I run the simulation the rope swings pendulum-like as expected. I placed a plane and ball below it and added collision to them. To test this I made a plane subdivided it and added a cloth modifier to it. When the cloth falls it collides with the plane just as shown in the video.
However, when the rope swings it does not collide with the plane or the ball but simply swings through them as if they are not there. This is in spite of the fact that the original string of verts has a cloth modifier.
I'm stumped.
