How to animate a split/crack in object I wish to animate this model so it splits apart/cracks and each piece falls away from each other once it has fallen onto the scene.


I have also tried to use Cell Fracture, the result is below:

What would the best way to to approach this problem? I don't want the crack to form until it has fallen down into the scene.
you will need to learn more about constraints in blender to do this. i would give a solid answer but im not good at constraints. i only know this because ive used constraints before to controll a metaball with an armature. there are probably lots of online tutorials about these. i also would comment this but i dont have enough reputation.
