SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This guide helps modders and designers ensure consistent creation, editing, and review of Victoria 3 technology definitions, reducing ambiguity and integration errors across the mod's tech graph.

Core Features & Use Cases

  • Definition scope: Clarifies where to place tech blocks (common/technology/technologies/*.txt) and how they interact with eras, production methods, buildings, laws, and institutions.
  • Validation guidance: Outlines prerequisites, modifiers, on_researched logic, and AI weighting to maintain a coherent research tree.
  • Use Case: When adding a new technology or overriding vanilla techs, pair it with related components (eras, production methods, or institutions) to ensure all unlocks and effects wire up correctly.

Quick Start

Edit a local Victoria 3 tech file under common/technology/technologies/*.txt to add or adjust a technology definition.

FAQPage Schema
How do I add a new technology in a Victoria 3 mod?

To add a new Victoria 3 technology, edit a text file under common/technology/technologies/ and define the tech block, ensuring you include a YAML frontmatter with a name and description for proper localization and validation.

What do I need to override vanilla Victoria 3 technologies?

Overriding vanilla Victoria 3 technologies requires editing local mod files in common/technology/technologies/*.txt, where you adjust the technology definition while maintaining coherent connections to eras, production methods, buildings, and laws.

How does Victoria 3 technology definition interact with eras and production methods?

Victoria 3 technology definitions map directly to eras, production methods, buildings, laws, and institutions through prerequisites and unlocks, ensuring all wired effects and research tree connections remain coherent across the mod.

Why are my Victoria 3 mod technologies causing integration errors in the tech graph?

Integration errors in the Victoria 3 tech graph occur when technology blocks lack coherent prerequisites, modifiers, on_researched logic, or AI weighting, which must be validated against related eras and institutions.

Can I use this guide to trace Victoria 3 technology unlocks to laws and institutions?

Yes, this guide helps trace Victoria 3 technology connections to laws, institutions, modifiers, and AI weighting, ensuring all unlocks and effects wire up correctly within the game's research tree.

What is the best way to validate Victoria 3 mod technology prerequisites?

The best way to validate Victoria 3 technology prerequisites is to review the on_researched logic, AI weighting, and modifier blocks in your common/technology/technologies files to maintain a coherent research tree.
