As you can see, there is a round doughnut in the box (there are more boxes and doughnuts but for now I haven't added them and anyway it would be less complex.) When the box falls down, I want this one to collide with more doughnuts like these and get them crushed. So when the box explodes open, I want some food objects (an example shown in the image) to tumble around, collide with each other, and get smashed/crushed. I tried doing this using cell fracture, but it didn't work.
In conclusion, I want some food items to collide and get smashed/cracked (and they're not hollow, they should be solid from the inside). I hope this much detail is probably enough.
Edit: Even the doughnut breaking into 2 pieces after falling down is probably enough, I guess.
Edit: Even though I found a way around cracking/smashing the food, I'm keeping the question open for any more ideas..... of how to do it without it getting hollow from the inside.
Here's the file on dropbox. Since the file is 40 MB (2 attached doughnuts add up to a million faces) blend -exchange takes forever to upload.
