YBN TUTORIAL
Welcome! In this in-depth YourMAPS tutorial we dive into YBN world collisions for RDR2/RedM, what they are, how the RAGE engine reads them, and the correct way to edit and stream them so your changes actually load in-game. We cover best practices (performance, stability) and show a practical example (Blackwater) using Blender + Sollumz and CodeX.
In this tutorial, you’ll learn:
- What is a YBN and the 3 types (static, instance, hi@)
- Static vs. embedded collisions (when to use each)
- How RedM/RDR2 read ybn file paths
- Exporting YBNs (CodeX World View / Explorer)
- Importing & editing collisions in Blender (Sollumz)
- Safely opening doorways (removing blocking faces, avoiding poly boxes)
- Converting back to .ybn and streaming it correctly
- Optional: handling occlusion meshes to avoid flicker
- Testing in-game and performance tips
By the end, you’ll know how to edit world collision meshes, and stream reliable world collisions with minimal performance cost on your server.
