Run mmaps_generator.exe. This step takes the longest—30 minutes to 2 hours—because it generates pathfinding tiles for every map, including dungeons and raids (e.g., Icecrown Citadel).
Do not interrupt it. Progress is shown tile by tile.
After completion, you will have an mmaps/ folder with many .mmap files.
The sequence DBC → Maps → VMaps → MMaps is non‑negotiable for any serious WoW 3.3.5a private server. Skipping any step yields a broken, unplayable world. By following the extraction guide above and validating each component, you ensure that your WotLK 3.3.5a server provides a stable, blizzlike experience—whether you’re hosting for 10 friends or 1,000 players.

Now that you have mastered map extraction, your next steps are scripting custom NPC behaviors, tuning mob respawns, or even building a custom raid. But always start with the maps—without them, there is no world to adventure in.

You do not need to extract these files from a World of Warcraft client yourself; they are already provided in the download.
Here is the proper guide to setting up and running this specific type of repack. Need advanced help
Role: Basic terrain and static object placement.
The maps directory (usually .map files) contains extracted terrain data: heightmaps, area IDs, liquid types (water/lava), and static world object coordinates. Unlike client maps, these are processed server-side to:
Generation: Extracted using tools like mapextractor from a clean 3.3.5a client. Without maps, players fall through the world.
| Component | Directory Name | Purpose | Criticality |
|-----------|----------------|---------|--------------|
| DBC | dbc/ | Client database tables (spells, talents, items, achievements) | High – Server will not start |
| Maps | maps/ | Terrain geometry, area boundaries, spawn coordinates | High – No world environment |
| VMaps | vmaps/ | Line-of-sight (shoot through walls), collision detection | Medium – Prevents wall hacking |
| MMaps | mmaps/ | Pathfinding (NPC movement, pet movement, navmesh) | Medium – Enables intelligent AI movement |
| Buildings (optional) | Buildings/ | Precomputed navmesh tiles | Low – Generated from VMaps |
