RDR2 Interior Lighting Tool

In early 2024 I joined the WildRP team - who are creating a custom roleplaying server in Red Dead Redemption 2 using RedM.

A large on-going problem with RDR2 modding was that nobody had solved the problem of lighting in custom interiors yet, in the 4 years that the game had been modded - reflections were missing and ambient lighting was entirely flat.

Upon joining the team, I did some research by looking through files, Rockstar patents, and rendering breakdowns, and figured out how the interior lighting system in the game worked. Using that information I created a tool to generate lighting data for our custom interior meshes - giving them the ability to blend in with the base game assets to a much greater extent.

The tool was written in Godot due to it's ease of use for rapid prototyping. It is open source and available on GitHub: https://github.com/WildRP/WildRP-AMV-tool
