I am using realflow and I want to model a building in maya, en then let it collapse in realflow (because I think it has better rigid body dynamics). But when I model it, and export it in OBJ format, it comes out in realflow as 1 big object. So for example if I create 5 cubes on top of eachother in maya, and then import it in realflow it is just 1 cube. The 5 cubes are grouped. How can I solve this?
