UETPFCore is an Apache 2.0-licensed forward looking framework leveraging experimental engine features and aims to become a simple production-ready, framework for building physics-driven programs and scientific simulations in Unreal Engine 5.7+.
It provides cognitive structure for projects with a robust ready-to-build subsystem architecture inside a minimal project aimed at high fidelity multi-scale simulations, supporting everything from planetary-scale coordinate systems down to centimeter-precision physics interactions.
- Large World Coordinates (LWC) integration
- Seamless km ↔ cm transformations
- Coordinate frame management for planetary bodies
- Precision handling across vast scales
- TimeSubsystem: Configurable time dilation and progression
- WorldFrameSubsystem: Multi-scale coordinate transformations
- EnvironmentSubsystem: Medium specs (air, water, vacuum)
- SurfaceQuerySubsystem: Material behavior (friction, deformation)
- BiomeSubsystem: Environmental region management
- PhysicsIntegrationSubsystem: Chaos physics integration
- MediumSpec: Fluid/atmosphere physics (drag, buoyancy, sound)
- SurfaceSpec: Contact material behavior (friction, compliance, FX)
- Data-driven specs via UE Data Assets
- Runtime-loadable configurations
- Sparse delta storage for world state changes

This framework is ideal for:
- Space exploration games
- Planetary surface games
- Multi-scale simulation games
- Physics-driven story games
- Flight simulators
- Vehicle simulations
This project is being submitted for the Epic Games Mega Grant program. The framework demonstrates production-quality systems architecture using Unreal Engine best practices and is designed to benefit the Unreal Engine community by providing a solid foundation for physics-based games and simulations. Helpful feedback that can help the platform succeed is welcomed.
The project also aims to benefit the larger developer community and the general public at large. We aim for the project to expand beyond games to facilitate cities to build robust simulations that can help iterate through climate resilience solutions affordably. We are currently using approximations for performance, however the project is built to be extensible to high fidelity implementations.
We are available to facilitate them.
