Fracturing valley

Here, I'm testing out the fracturing in DOP before carrying out the actual simulation: The intended effect is to have the pieces crumble as they fall.

After successfully doing the fracturing test in DOP, I've started some test fracturing on the actual geometry. However, the falling geometry (red) is not falling realistically, and is falling together as a chunk instead. Hence, I'm using a sphere to break up the chunks as they fall.

Here, I'm experimenting with animating the sphere to get a more realistic result.
