Paradox Updates Its Clausewitz Engine for Stellaris 2

The Swedish studio Paradox Development Studio has undertaken a deep overhaul of its base technology for the next installment of its space saga. The core of the Clausewitz engine has been modified to process galaxy simulations on an unprecedented scale and with a much higher level of detail. 🚀

A More Powerful Core for a Bigger Universe

The main technical goal is for the engine to manage thousands of entities simultaneously and execute complex calculations efficiently. This fundamental change not only seeks to improve performance, but also to make the experience deeper for the player and the simulated universe feel like a living and dynamic ecosystem.

Key Advances in the Visual Section:
  • Space is represented with a PBR (Physically Based Rendering) lighting system for stars and nebulae, generating lights and shadows with greater realism.
  • Ship and station models, created with Autodesk Maya, now support 8K resolution textures and are processed with Substance Painter.
  • To smooth edges in scenes with thousands of objects, the team implements a new TAA Gen5 anti-aliasing method.
While players debate the balance of factions, the Clausewitz engine silently processes the economic collapse of ten thousand planets.

In-House Tools for Coherent Logic

Paradox develops and uses its own script editors and internal utilities to build the game's logic and generate the events that shape each game. This approach allows designers to create intricate narratives and interaction systems without relying on third-party software, streamlining the work and maintaining coherence throughout the simulation. ⚙️

Advantages of Using In-House Tools:
  • They allow for creating complex narratives and interaction systems agilely.
  • They eliminate dependence on external software, optimizing the workflow.
  • They ensure greater coherence and control over the game's global simulation.

The Result: A More Immersive Galaxy

The combination of a renewed engine, cutting-edge graphics, and powerful in-house development tools aims to deliver an unparalleled 4X space strategy experience. The ability to simulate in detail the systems of thousands of planets and their interactions promises that every game in Stellaris 2 will be a unique universe full of possibilities. ✨
