Machine-Learned Physics: Training Destruction Models for Hyper-Real ChaosMachine-Learned Physics: Training Destruction Models for Hyper-Real Chaos
May 2025
Studios no longer hand-tune every fragment and dust cloud by hand. Instead, they feed thousands of crash-test videos and demolition simulations into neural networks that learn to predict debris trajectories, particle density, and structural collapse in real time—even on mid-tier hardware. The result: blockbuster destruction that runs at 60 FPS on consoles and 45 FPS on gaming PCs [demo].
📊 Real-World Case Study: Avalanche Studios’ Volcano Demo
Avalanche Studios trained a destruction model on 10,000 high-speed recordings of volcanic rock collapse [SIGGRAPH talk]. The network learned to predict rubble flow, achieving 80 percent accuracy in debris spread within 0.1 seconds of real time. When integrated into their engine, they reduced CPU physics calls by 60 percent and GPU particle time by 45 percent [NVIDIA PhysX].
🛠️ Data & Metrics
- 🛠️ Dataset size: 15 TB of high-res simulation video frames [archive]
- 🛠️ Training time: 72 hours on 8 × A100 GPUs [A100 specs]
- 🛠️ Performance gain: 60 percent fewer physics ticks per frame
- 🛠️ Real-time output: 1 million particles simulated per frame

The key to a $1.3T opportunity
A new real estate trend called co-ownership is revolutionizing a $1.3T market. Leading it? Pacaso. Led by former Zillow execs, they already have $110M+ in gross profits with 41% growth last year. They even reserved the Nasdaq ticker PCSO. But the real opportunity’s now. Until 5/29, you can invest for just $2.80/share.
This is a paid advertisement for Pacaso’s Regulation A offering. Please read the offering circular at invest.pacaso.com. Reserving a ticker symbol is not a guarantee that the company will go public. Listing on the NASDAQ is subject to approvals. Under Regulation A+, a company has the ability to change its share price by up to 20%, without requalifying the offering with the SEC.
⚠️ Limitations & Caveats
These models can struggle with ultra-fine debris (particles <0.5 cm), requiring fallback to standard particle emitters. Training costs remain high—over $20,000 in cloud compute per project—and random frame artifacts can appear when fed out-of-distribution collapse scenarios [community feedback].
đź’¬ Community Spotlight
Indie studio ChaosForge used ML destruction to drive their hit mod “Ruin & Rebuild.” Founder @ModMaster on Twitter notes: “We shaved 50 percent off physics budget and unlocked new gameplay systems.” [tweet]
🔧 Tip of the Week
🔧 When training destruction nets, augment data with edge-case demolition videos to reduce artifacts.
