MAGIC: Transition-Aware Generation of Navigable Multi-Scene Game Worlds with Large Language Models

2026-07-13 · Source: Artificial Intelligence · Field: Technology & Digital — Artificial Intelligence & Machine Learning, Gaming & Interactive Media · Depth: Expert, quick

Summary

MAGIC is a novel prompt-to-project system designed to automate the generation of navigable multi-scene 3D game worlds using large language models (LLMs). It tackles the laborious challenges of authoring multi-scene navigation, specifically cross-scene consistency, in-scene navigability, and the evaluation of functional transitions between scenes. The system employs a four-stage pipeline: planning a shared transition-aware intermediate representation, specifying each scene while enforcing portal reachability with a flood-fill validator, generating scenes with their transition scripts, and combining them into a runnable project. To validate its effectiveness, MAGIC introduces a transition-focused evaluation agent. On a new benchmark of 100 multi-scene cases, MAGIC successfully produces an executable project for every case, achieving 0.99 precision, 0.95 recall, and 0.96 F1 on end-to-end transition identification, outperforming an LLM baseline and Holodeck in recovering ground-truth portals and yielding navigable layouts.

Key takeaway

For AI Engineers developing complex 3D game environments, MAGIC offers a robust solution to the challenges of multi-scene navigation. You should consider integrating this four-stage pipeline to automate consistent portal connections and ensure in-scene navigability, significantly reducing manual authoring effort. This system's demonstrated 0.96 F1 score for transition identification suggests a reliable approach for generating executable, connected game projects, allowing your team to focus on creative content rather than tedious consistency checks.

Key insights

MAGIC automates multi-scene game world generation, ensuring navigability and consistent transitions via a four-stage LLM-driven pipeline.

Principles

• Multi-scene navigation demands consistency.
• In-scene navigability requires validation.
• Transition functionality needs execution.

Method

MAGIC's four-stage pipeline plans a transition-aware representation, specifies scenes with flood-fill validation for portal reachability, generates scenes and scripts, then combines them into a runnable project.

In practice

• Generate connected 3D game levels.
• Automate portal consistency checks.
• Evaluate scene transitions in play.
