Hello,
Is there any way where we can create the fractures procedurally/dynamically based on the Chaos Master fields placements rather than pre-defining it and simulating the destruction based on the chaos. Any help regarding this matter would be appreciated. Thanks
Note: I want to create radial fractures at the point of master field contact on the road.
Hello Sandy, Yes you can dynamically create radial fractures in Unreal Engine using the Chaos Destruction system by leveraging Chaos Fields. This approach allows you to procedurally fracture geometry at runtime based on the placement of Chaos Master Fields
Tutorial
Doc:
Trigger Fractures at Runtime:
To activate fractures dynamically:
Place the Field System Actor with the Radial Falloff Field at the target location on the road.
Adjust the field’s parameters, such as magnitude and radius, to control the fracture’s appearance and behavior.
This setup ensures that when the field is activated, a radial fracture pattern emanating from the point of contact is induced.

Hekki @BRGEzeHulton Thanks for the help and references. I have another question regarding the chaos destruction, When I tried to make my landscape thinner and trigger the chaos field the physics get messed up and my entire landscape is fractured and the debris are floating in the sky. Do you have any idea on why this is happening and how can I mitigate this effect. Thank you in advance.
This usually happens when the landscape (or destructible object) becomes too thin. Chaos needs some thickness to generate stable fragments. If it’s too thin, fragments become unstable and start floating or acting weird.
Try converting the destructible part of your landscape into a solid static mesh with proper thickness (30–50 cm).
In your Geometry Collection, make sure you increase the minimum mass and enable “Mass as Density”.
Also, check your Chaos Field strength and radius, they might be too high.
Landscapes aren’t ideal for Chaos destruction, so using a custom mesh will give you more control. Hope this helps!
