我们将学习使用刚体1中对刚体模拟进行实例化的操作，将它应用到一个很精细的建筑破坏教程中，我们将讲解很多关于高级限制创建，管理技术，替换实例化几何体，应用自定义作用力等

In Rigids II, we will take what we learned about leveraging instancing in rigid body simulations from Rigids I, and apply it to a super-detailed building demolition! We will talk a lot about advanced constraint creation and management techniques, swapping instance geometry, and applying custom forces and rules for breakage. After we find the best simulation parameters by wedging our simulations, we’ll render out a great looking sim!
