Hey fellow developers! 
Recently dived into the Chaos Destruction in Unreal Engine 4.26? If you’re a bit tangled with the setup, don’t fret! The Chaos Destruction Demo for 4.26 might seem a little tricky at first because of its dependency on a source build. But trust me, once you enable Chaos and give it a fresh rebuild, it becomes smoother.
I’ve outlined a simple three-step process to make your journey less bumpy. Do check out the files ChaosDestructionDemoEditor.Target.cs and ChaosDestructionDemo.Target.cs linked above (link 709) - they’re a lifesaver! Just replace them in the mentioned paths, and you’re golden. 
If you’re more of a hands-on coder, there’s an alternative for you as well. Just copy-paste the code snippets provided above to the corresponding files. Ensure your configurations match, and then just revel in the awesomeness of Chaos Destruction. Let’s keep the chaos only in the demo, not in our setup, right? 
Stay curious and keep building,
Abdullah
