This is the only guide ever shared to generate geodata from the client.

 

Tools needed.

L2J-GeoEditor (Convert to L2J format and create the PathNode)
Download: http://www.mediafire.com/file/1j5lhll1mn1uy2x/l2j-GeoEditor-v17.zip

 

HEX Editor - (I use UEStudio or Ultraedit)
Download: Find it on the web :P

 

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

 

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".

    * 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.

Hello, a bit late i know but i had the same problem as above, finally managed to find a solution.

 

You have to change Windows Region to: English (United Kingdom).

Spoiler

 

This worked perfectly for me.

what about creating GEODATA for custom map? 

Hi Bros, im starting to edit some maps but i didnt found any wiki that shows how to use g3deditor or any editor. What is te functionality of de buttons with triangles ? and the colors? .

sorry duplicate contet, cant delete

Thanks, the guide is very useful.

I have this problem, is there any solution?

When extracting heightmap images from UTX files,Multiple files 18_15.raw, 18_15deco01.raw, 18_15G001.raw, etc. were extracted from the UTPackage/RAW folder.

Do you need to extract all the new images (18_15.BMP, 18_15deco01.BMP, ..., 18_15S005.BMP)?

the other textures are like you can read for decoration purposes only. unreal needs those to apply texture to the ground and for example grass, debris or whatever deco u want to your heightmap

Thank you for your reply!
