Welcome to this detailed tutorial on mastering YBN collisions for MLO interiors in RedM — especially when dealing with rotated shells and complex portal setups.
If you've ever run into weird rooms overlapping issues like weird lighting, missing props, or glitchy interiors because you did not rotate your MLOArchetype resulting on misplaced rooms, this guide will walk you through the correct way to align everything — and keep your Ybn interiors bug-free clean and performant.
Here’s what we’ll cover:
✅ The Importance of MLO Room System in RedM – Learn why rooms matter and how portals optimize rendering.
✅ Why Overlapping Rooms Are Bad – Avoid performance hits, lighting bugs, and flickering props.
✅ Rotation Explained – How to handle YBNs for rotated shells using Euler angle degrees and Quaternions angles.
✅ YTYP & YMAP Setup – Sync your collision, drawable, and placement the right way.
By the end of this tutorial, you’ll know how to:
Create precise, non-overlapping room & collisions
Rotate and align your YBNs
Avoid common pitfalls with MLO setups and achieve clean interior performance
No more "why I have this rotation on my ybn?" problems.
