How to drag rigid bodies with a rigged mesh? I started the animation of my project and I want to carry stones from one place to another. I am using rigid bodies on the stones so each one of them is an individual object. Here in the first picture are they in the initial position. 


But when I move the loader in a diferent frame the stones stay in the initial position like in picture 2


How can I move these stones with my rigged mesh (front end Loader)?
Rigid body objects only interact with other rigid body objects. To make the loader bucket "pick up" the rocks it will need to have rigid body enabled. As you are using an animation to move the bucket you should enable the animated option. You also need to set the collision shape to mesh so that the bucket will be hollow to allow the rocks inside it.





You will also want to use similar settings for the truck.
