why chain not fall on the ground? With the chain as active and ground as passive created rigid body. Why the chain unable to drop on the floor. Chain is going through the mesh. Any suggestion whats going wrong
For your ground you've chosen Collisions but Collisions is for Cloth or Soft Body, you need to choose Rigid Body, Type &gt; Passive and Shape &gt; Mesh.
Also, apply the ground scale and apply the chain modifiers (I'm not sure why it messes up the simulation though)
