CodeWalker tutorials. FiveM mapping, step by step.

CodeWalker controls, shortcuts and world navigation

Learn the world camera, selection mode, transform widgets, Project Window and archive explorer without confusing their controls.

Getting started

Beginner5 min read

Create your first FiveM YMAP

Place a small group of existing props, calculate the map bounds, and turn the result into a resource you can test.

Mapping

YMAP, YTYP, YDR, YTD and YBN files explained

A practical guide to the files behind a FiveM map: what each one owns, what it does not own, and where to investigate a failure.

Reference

Connect Blender, Sollumz and CodeWalker

Set up a small, versioned asset pipeline and round-trip one original prop before committing to an entire interior.

How to create a FiveM MLO

Build a small two-room interior with Blender, Sollumz and CodeWalker, then package and test it as a FiveM resource.

MLO creation

Make rooms and portals work

Use a two-room test to separate portal connectivity, room bounds and visibility problems from collision problems.

MLO creation

Build collision you can actually walk on

Separate visible geometry from collision and test floors, entrances and room boundaries with a reproducible route.

Stream your map as a FiveM resource

Build a clean resource, register custom YTYPs, start it on a development server, and verify the delivered files.

Deployment

Expert4 min read

Optimize an MLO without guessing

Establish a repeatable camera route, measure changes, and distinguish geometry, textures, visibility and streaming costs.

Optimization

Expert5 min read

Diagnose missing or flickering interiors

Use the symptom to choose the next check instead of cycling through cache deletion, draw-distance changes and random flags.

Troubleshooting

Expert3 min read

Build a repeatable MLO release checklist

Package a matched set of assets, test realistic approaches and transitions, and prepare a rollback before distributing a map.

Deployment

Convert XML to YMAP: Menyoo, Map Editor and CodeWalker

Identify your XML format, convert supported prop placements to YMAP, then check native output and package it for a FiveM test server.

CodeWalker not loading: startup, black screen and missing world

Diagnose CodeWalker startup errors, a black viewport and a missing GTA V world with staged checks for extraction, game paths, graphics and build compatibility.

Remove objects in CodeWalker without breaking the surrounding map

Distinguish deleting your own YMAP placements from overriding vanilla map data, collision, LODs and scripted props. Keep changes isolated and reversible.

Find GTA V prop names, hashes and their source files

Identify a GTA V object in CodeWalker, distinguish its archetype from its placement, and check dependencies before using a prop name in a FiveM map.

CodeWalker on Mac: browser planning, Blender and Windows handoff

Understand which parts of the CodeWalker mapping workflow run in a browser or Blender on macOS, and where Windows compilation and FiveM tests are still needed.
