In this series we will cover how to create destructible assets using Chaos.
In Part 4 of this series, we will be covering the Geometry Cache which allows you to cache your Chaos simulation for more efficient playback of your simulation in-game. We also take everything we’ve learned in this series, and apply it to an actual environment where we simulate a rock fall across a winter road using the FREE “Automotive Winter Scene” environment on FAB, created by Epic.
