Rigid Body breaking links of chain I have made some chain links. I used the Rigid Body Tools and made the two end links passive and the others active. They are all set to shape Mesh. I've tried setting the weight to acrylic, cardboard, etc to lessen the pull they have when falling. How do I prevent these links from coming apart? I've even tried scaling up the scene but that also doesn't work.

From Blender 2.91, there is now a &quot;compound parent&quot; shape option dedicated to this kind of shape (with concavities):

You can find its description from the release page here.
And in the documentation:

Compound Parent
Takes the collision shapes from the object’s children and combines
them.
This makes it possible to create concave shapes from primitive shapes.
This usually results in a faster simulation than the Mesh collision
shape while also being generally more stable.
