Ice cracking fixed

I finally managed to crack the ice. At first, I had a lot of issues with the ice cracking, due to problems with booleans. After spending a while talking to my supervisor and reviewing the boolean difference options, I decided to go down a different route. I used multi cut to cut up the surface mesh before creating clusters for the crack edges. Following this, I created an ocean surface under the ice and animated the clusters. This solved the problem and I was finally able to animate the ice.
