I have a scene, with some assets linked into it. Among them is a rigged character, linked by a group instance. The rig is well "proxied", and animated. I modeled a scarf, and wanted to make a cloth simulation. The part of the scarf which is around the neck of the character is parented to the neck's bone, and defined as "Pin" in the cloth parameters.
Now, I don't want the scarf to go through the body of the character, so I came back to the character's blend file, added a collider to the body, saved, and re-opened the scene. Nothing changed. The scarf still passes through the body. There is no cache applied.
Am I missing something ?
