Horizon Forbidden West Relies on the Enhanced Decima Engine

The technology behind the acclaimed open world of Horizon Forbidden West is an evolved version of the Decima engine. This graphics core specializes in building vast and believable landscapes, with meticulous attention to organic detail. 🎮

Technical Capabilities of the Engine

This engine can process a huge amount of elements simultaneously. It smoothly manages dense forests, water surfaces with real-time deformations, and the complex behavior of caustic light. Additionally, it integrates dynamic weather systems that change the environment. The PlayStation 5's solid-state drive allows for a drastic reduction in loading pauses while exploring the map.

Visual Strengths:
  • Character and mechanical creature models with very high geometric detail and natural movements.
  • Sky and atmosphere rendering using techniques to simulate volumetric clouds and other phenomena.
  • On PS5, high image fidelity is achieved with modes that prioritize frames per second or resolution.
Sometimes, the biggest technical challenge is not showing a colossal machine, but preventing the grass from visibly piercing through the character's feet.

Workflow and Software Used

To shape this universe, the development team used the Decima Editor as the central tool. This environment was complemented with specialized applications for each creative task.

Key Tools in Production:
  • Maya and ZBrush: Used for modeling and digitally sculpting all assets, from characters to machines.
  • Houdini: Employed to simulate complex effects like cloud formation, object destruction, and other procedural systems.
  • Substance 3D Designer and Painter: Essential for creating and applying realistic textures to materials efficiently.

The Result of Refined Technology

The combination of the enhanced Decima engine with a powerful workflow and PS5 hardware results in a living and believable world. The technology not only serves to impress with grand spectacles but also to polish the small details that immerse the player. The focus is on creating a coherent and fluid visual experience at every moment of the adventure. 🌄
