Causing Chaos - Physics and Destruction in UE4 - SIGGRAPH 2019 - Unreal Engine

Explore the future of physics and destruction in Unreal Engine through this SIGGRAPH 2019 conference talk. Dive into features that empower content creators to build highly interactive worlds capable of fracturing, shattering, and demolishing. Discover the Chaos system, its management, and practical applications in navigation, AI reactions, and damage detection. Examine advanced techniques like geometry collections, fracturing, sub-fracturing, and performance optimization through clustering. Delve into the Chaos Field System, large-scale simulation caching, and the underlying technology powering Chaos. Learn about non-convex collisions, Niagara integration, interactive caching, and physics threading. Gain insights into destructible LODs, dynamic strain evaluation, and strategies for enhancing Chaos performance. Presented by Jim Van Allen, Matthias Worch, and Michael Lentine from Epic Games, along with Jeff Rous from Intel, this 45-minute talk offers a comprehensive look at cutting-edge physics and destruction techniques in Unreal Engine.
