1 - Open data folder gameserver\data 2 - Copy contents folder geodata in gameserver\data\geodata 3 - Copy contents folder pathonde in gameserver\data\pathnode 4 - To use the Geodata you must go on gameserver/config/head/geodata.properties

SET GeoData =

0 = geodata disabled (default). 1 = enabled geodata.

If ForceGeodata = true, it requires ~ 3 GB If ForceGeodata = false, then the required rate of screws 7200

2 = geodata and patchnod (search path) are included.

If ForceGeodata, ForcePathNod = true, it requires about 5 GB If ForceGeodata, ForcePathNod = false, then the required rate of screws 7200

-1 = Patchnod (search path) enabled.

If ForcePathNod = true, it requires about 2 GB If ForcePathNod = false, then the required rate of screws 7200

Test function! There may be mistakes!

Tools needed:

• Stazis L2 Geo Converter
• G16ed - a heightmap editor that works directly with the UEd3 G16 format (16-bit greyscale)
• UTPackage - to extract game resources
• Unreal Engine 2 Editor - to create UTX packages
• L2J-GeoEditor - to convert to L2J format and create the PathNode
• HEX Editor (UEStudio or Ultraedit)

Important: In this example I will use the map T_22_19, but applies the same procedure for any map.

Important: If you use a Classic map remove _Classic from both Textures and MAP file names.

First we need to extract heightmap images from UTX files (T_22_19.UTX, T_22_20.UTX etc.)

• Put this file T_22_19.UTX in UTPackage/Textures and execute "unpack.bat"
• Open UTPackage/RAW folder and find the file 22_19.raw
• Open this file with Ultraedit and search (Ctrl + f) for "40 80 10", the first byte after this string is the start of the heightmap image.
• Copy this address, in this case is 107h
• Open the windows calculator and switch to "Scientific" mode, select "Hex" and input "107", select "Dec" and now you have "263".
• Open G16ed, go to "File -> Import -> RAW data, search for 22_19.raw and in the field "Data start offset" input "263" and click in Input, Ok, Ok.
• Go to "File -> Save (Ctrl + S)" and use the name of the map for your new image (22_19.BMP). Now you have a perfect G16 heightmap image.

Now we need to create an UTX file with the image that we have saved.

• Open UnrealEd and in the windows "Textures" go to "File -> New" and complete the fields. Info -> Package: T_22_19, Group: Height, Name: 22_19, Class: Raw Material Properties -> MaterialClass: Class"Engine.Texture" (Select Texture from drop-down)
• Go to "File -> Import" and select the image 22_19.BMP and ensure that the fields are correct. Info -> Package: T_22_19, Group: Height, Name: 22_19 Options -> Masked: uncheck, Generate MipMaps: uncheck, Detail Hack?: uncheck, Compression: none
• Go to "File -> Save" and save this file as T_22_19.utx. Now we can create our Geodata using Stazis L2 Geo Converter (GeoConv)
• Navigate to the Textures folder in the game, rename your original T_22_19.utx to T_22_19_O.utx and put in this folder our new T_22_19.utx
• Open GeoConv and change this params. Min Plane Angle to XY: 20, Stairs Height: 10, Optimization Different: 80
• Click "Open Packages" and select 22_19.unr in "Lineage II/MAPS", allow the process to finish and now you have your GEO 22_19_conv.dat in the folder "Lineage II/MAPS".
• If you get an error here, change your system's decimal symbol to . from Control Panel -> Regional Settings.
• Convert this GEO to L2J format and create the PathNode with L2j GeoEditor or HDGE.

Known Issues:

• Some geodata are not correctly generated or can't be generated.
• Using "Stairs Height: 10" can cause problems with the stairs (If you use "8" check all the stairs in the map for correct NSEW).

Further manual adjustments can be made using G3DEditor.
