Enhanced Validation - Lessons From a Custom AAA Implementation

Explore how LightspeedLA enhanced Unreal Engine's validation system in this 51-minute conference talk from Unreal Fest Bali 2025. Discover the implementation of custom validation enhancements that extend beyond assets to cover actors and restrict search depth for aggregate assets like Level Instances. Learn how this robust submission workflow dramatically reduced build breakages from multiple daily occurrences to just two or three weekly support requests for asset error resolution. Examine the technical details of the validation system architecture and understand how it prevents asset errors before submission. Gain insights into future validation developments including more user-friendly messaging systems, potential code and Blueprint validation capabilities, and self-serve error fixing through the Fixer framework. Understand the practical challenges and solutions involved in implementing AAA-level validation systems that maintain code quality and streamline development workflows in large-scale game production environments.
