Question

Hello i am trying to make a balance game with different shapes that resemble meat cuts. I import my assets directly from blender but i cant seem to find a way to have physics on them as static bodies. Static body is the only way to have the right collision shape with concave, but i need them to have gravity in order to make them stack and feel more like balancing them for the player.
