Summary
Congratulations! With that, you have created an amazing physics simulation using Rigid Body physics and constraints! You have learned how to install the required Blender add-ons, Cell Fracture and Import-Export STL, and how to use them. You should now be familiar with the Cell Fracture add-on and how to use it to break objects into smaller fragments by using automatic fracturing or making use of the Annotation Pencil to specify where to fracture objects.
You also learned how to apply Rigid Body physics to the fractured pieces and how to tweak the parameters to adjust your simulation. We also looked at how you can link the fractured pieces together using Rigid Body constraints to create a more realistic simulation. After that, we added an animated object to our scene that will interact with your simulation. Lastly, we learned how to bake the final simulation to cache.
Simulations are all about experimenting and tweaking parameters one at a time to see how they affect...
