Unreal Engine - Chaos Physics

real-time technology is changing industries across the spectrum wherever the need for high fidelity photo realistic visuals proven performance or interactive experiences unreal engine provides a solution as the world's most open and advanced real-time development platform adding to the infinite creative possibilities Unreal Engine employs a powerful dynamic physics and destruction system with chaos destruction with chaos users can achieve cinematic quality visuals in real time in scenes with massive scale levels of destruction and unprecedented artist control over content creation the chaos destruction system is a collection of tools with an unreal engine that provides several core benefits including a quick and intuitive workflow allowing artists to quickly learn develop and rapidly create stunning dynamic effects real time performance real time performance not only benefits the playback it also empowers creators to develop and simulate seeing the results immediately on screen as they work in addition chaos is not dependent on specific hardware coding meaning that the simulations can be produced and played back on any capable performant GPU before we dive into a demonstration let's explore the technology behind chaos destruction within the chaos system starts with a new kind of asset called the geometry collection this is where the destructible piece or pieces are defined once you have your geometry collection inside the fracture editor you can choose the type of fracture to perform and the settings use to perform that fracture clustering and performance this is a way of collecting how the fractures will behave and to what extent these can be further combined to increase more dynamic results the field system of then the chaos destruction tools is a way of directly affecting a physics simulation by occupying a region of space with varying parameters in order to produce different behaviors or breakage effects anchors can be used to lock portions of a geometry collection in place while the rest of the geometry collection breaks apart chaos solvers within the chaos destruction system can store important data such as a list of collision breaking and trailing events as the simulation runs Niagra unreal engines high-performance particle system for creating high quality effects such as smoke dust water and fire can take the chaos data and utilize this in a multitude of ways here we see chaos and aggro working together to generate destruction smoke dust and additional debris pieces as the simulation runs so how does chaos work well let's take a look at an overview of how chaos works in editor starting with a piece of geometry in this case a simple cube we can access the chaos fracture editor to add our object to a geometry collection or chaos is way of defining items to be destroyed play back the scene and we now have some basic physics applied but let's add some dynamics now selecting the cube and using the default settings we hit the fracture button and we now have a cracked and shattering object adjusting attributes such as mass and density is quick and easy let's now take this a step further and apply chaos to a building model example here are progressing the same process further along we can adjust the overall damage threshold and apply things like anchors to control customize and add some randomness to the overall physics of course like everything else in Unreal Engine we can develop this in infinite directions here we're using blueprints to apply forces and effect damage in a localized area so there we have a brief look at unreal engines next generation high-performance physics and destruction system with chaos Unreal Engine is the world's most open an advanced real-time 3d creation platform continuously evolving to serve not only its original purpose as a state of the art games engine today it gives creators across multiple industries the freedom and control to deliver cutting-edge content interactive experiences and immersive virtual worlds [Music] you

Would love to see a lower level version of this in Spider Man. Excessive destruction isn’t necessary, like buildings collapsing, but would be great to have destruction as a result from things like boss fights etc.

[u/QUAZZIMODO619]

Can be done, the main problem isn’t the power but the game design with having a destructible city. You can’t have things destroyed and then respawn in a game like gta so the whole game would need to be designed around the destruction like RF Guerrilla, maybe Prototype 3? I’d love P3.

[u/MrRonski16]

I hope that next battlefield will have fully destructible environments. And if its modern I want skyscrapers fall just like in bf 4

Always wanted this for Just Cause series. Mercenaries Playground of Destruction had this in a very basic PS2 way back in the day. Mercenaries was a fantastically designed game.

Possible, yes. Probable? Who knows. Seems like a lot of work, but keep your fingers crossed.

[u/bro2017]

It would be cool, but I’m not sure how necessary it is. 20 years from now, I’m not sure this would be a debate anymore.

What I would rather have in future GTA is the ability to go virtually into any building and explore it.

[u/BlueChamp10]

would love to see this in a sandbox Rampage game.

Hell yeah. Would live to drive though a house and crash a plane into a skyscraper. Hell they can even make us go into space and come back. Would even like if we can access all the buildings rather than being limited to the streets and our hotels/bunkers.

There will be a game this gen that uses realistic destruction as its marketing but underneath it will be completely shallow empty experience where the destruction is the only interesting thing.
