How do i get these cracks to disappear? How do i get these dreaded cracks in this sphere to go away? By the way i'm using the cell fracture add on to make a building crack when hit. I've tried to use the subsurf modifier but i am kind of a noob at blender. So can i get these cracks to go away? or am i approaching this animation the wrong way?
If you use the Cell fracture addon, there is an option called Margin. It sets the space ('cracks') between the fractals. If you see these cracks, the reason may be that your Margin is set too high.

Ensure, that it is not too small, because otherwise the physics engine thinks that the parts are intersecting each other, calculate a repelling force and this will tear the the ball apart.
