+
+This modding tutorial is intended only for Steam version Otherworld Legends. If you are targeting Android, you will need
+to do a few additional steps to deal with apk. I won't do this unless someone requests it.
+
+Author: Kolyn090
+
+Game version used in this tutorial: v2.9.1
+
+Windows x64
+
+Date: 5/15/2025
+
+⚡ **IMPORTANT**: Modding comes with unknown risks, including potential game 
+instability, corrupted save files, compatibility issues, and even security 
+vulnerabilities. Always back up your game files and proceed with caution.
+Proceed at your own risk – I can't take responsibility if things go sideways.
+
+# Step 1️⃣
+First, get AssetStudio.net6.v0.16.47 from [AssetStudio](https://github.com/Perfare/AssetStudio/releases). 
+Also install [.NET 6.0](https://dotnet.microsoft.com/en-us/download/dotnet/6.0)
+into your PC.
+
+Next, get the eight release of [UABEA](https://github.com/nesrak1/UABEA/releases) and get
+[Visual Studio 2022 IDE](https://visualstudio.microsoft.com/vs/) the Community version. 
+On your PC search bar, type "Visual Studio Installer" and open it.
+Under Installed, you should see Visual Studio Community 2022. Click Modify. 
+Enter "Visual C++" in Individual components. You should see a component
+called C++ 2022 Redistributed Update. Download and install that. Close your Visual
+Studio Installer and reboot your PC.
+
+Also, you are going to need [AddressablesTools](https://github.com/nesrak1/AddressablesTools/releases).
+Choose Examples release 2. After that download and install [.NET 8.0](https://github.com/nesrak1/AddressablesTools/releases).
+
+# Step 2️⃣
+Navigate to the Steam folder where the game is stored. For example:
+```
+Local Disk (C:)/Program Files (x86)/Steam/steamapps/common/Otherworld Legends
+```
+
+<img 
+    src="/marblestack/imgs/aa/a/game_folder.png" 
+    width="300" 
+    style="display:block; margin: 0 auto;"
+    alt="game_folder"
+/>
+
+The key is that you should see the `.exe` of playable game once you redirect to this folder 
+but in this case we are interested in the Otherworld Legends_Data folder (which should be in the 
+same directory as the game).
+
+Open Otherworld Legends_Data -> SteamingAssets -> aa -> StandaloneWindows64
+
+Here is the collection of replaceable game assets. E.g. if you want to change the skin of one of the
+heroes, open spriteassetgroup_assets_assets -> needdynamicloadresources -> spritereference.
+
+I will stick with changing hero skin in the rest of the tutorial but you should be able to adapt the knowledge
+to other types of asset as well. 
+
+<img 
+    src="/marblestack/imgs/aa/a/spritereference_unit_hero.png" 
+    width="300" 
+    style="display:block; margin: 0 auto;"
+    alt="spritereference_unit_hero"
+/>
+
+Search "unit_hero" in File Explorer. You should see many `BUNDLE` files.
+Keep in mind that the hero's internal name in the game's code may differ 
+from their display name in the game. For example. Quan Huying is identified by 
+quanhuying while Ginzo is identified by seebee. But don't worry, we can apply
+AssetStudio to see the underlying assets.
+
+# Step 3️⃣
+
+Extract AssetStudio. Locate `AssetStudioGUI.exe` and run it. 
+Click File -> Load file. For the sake of this tutorial, I will use Ginzo
+as example. In folder spritereference, search for unit_hero_seebee. 
+Choose the top search result (should be Ginzo's default skin). Open the 
+asset file in AssetStudio.
+
+<img 
+    src="/marblestack/imgs/aa/a/unit_hero_seebee.png" 
+    width="300" 
+    style="display:block; margin: 0 auto;"
+    alt="unit_hero_seebee"
+/>
+
+In AssetStudio's toolbar panel, locate Asset List. You should now see Ginzo's
+Sprites (shown in Preview). However, our main focus here is the file with 
+Type of Texture2D. It's called unit_hero_seebee. Select the file, in toolbar,
+locate Export -> Selected assets. Save the Texture2D to your PC. Close AssetStudio.
+
+<img 
+    src="/marblestack/imgs/aa/a/asset_studio_seebee.png" 
+    width="300" 
+    style="display:block; margin: 0 auto;"
+    alt="asset_studio_seebee"
+/>
+
+In the exported Texture2D folder, you should see a `.png` inside. Modify it
+using a pixel art editor software such as Aesprite or docpict, etc. Save your work
+as `.png` as well.
+
+<img 
+    src="/marblestack/imgs/aa/a/aseprite_seebee_example.png" 
+    width="300" 
+    style="display:block; margin: 0 auto;"
+    alt="aseprite_seebee_example"
+/>
+
+# Step 4️⃣
+
+Now let's swap game assets. Extract UABEA and locate `UABEAvalonia.exe` and open it.
+Click File -> Open. -> Locate the unit_hero_seebee file from earlier and open it. 
+You should see a popup window. Choose Memory. Now you should see everything loaded into the 
+software. Here we are only interested in the file with Type being Texture2D. Enlarger
+the window to see file Type.
+
+<img 
+    src="/marblestack/imgs/aa/a/uabea_assets_info.png" 
+    width="300" 
+    style="display:block; margin: 0 auto;"
+    alt="uabea_assets_info"
+/>
+
+<img 
+    src="/marblestack/imgs/aa/a/replace_texture.png" 
+    width="300" 
+    style="display:block; margin: 0 auto;"
+    alt="replace_texture"
+/>
+
+Open and select that file. On the toolbar to the right, find Plugins -> Edit texture -> Ok.
+Click the Load button and locate your modified version (`.png`) to replace it. 
+Click Save. In the Assets Info window, also do File -> Save. In the UABEA window, also
+do File -> Save. Now you can close UABEA. 
+
+# Step 5️⃣
+
+Extract addrtool-example-windows. Open and find `Example.exe`. Make a note on the
+location of this program. For example
+
+```txt
+"C:\Users\kolynlin\Downloads\AddrTool\Example.exe"
+```
+
+Next look catelog.json. On my PC, it's located at
+
+```txt
+"C:\Program Files (x86)\Steam\steamapps\common\Otherworld Legends\Otherworld Legends_Data\StreamingAssets\aa\catalog.json"
+```
+
+Confirm the existence of this file and record yours.
+
+After you have recorded those two, open up Command Prompt (search it on your PC).
+Enter the following command (⚠️This is mine. Remember to change to yours)
+
+```txt
+"C:\Users\kolynlin\Downloads\AddrTool\Example.exe" patchcrc "C:\Program Files (x86)\Steam\steamapps\common\Otherworld Legends\Otherworld Legends_Data\StreamingAssets\aa\catalog.json"
+```
+
+<img 
+    src="/marblestack/imgs/aa/a/command_prompt.png" 
+    width="300" 
+    style="display:block; margin: 0 auto;"
+    alt="command_prompt"
+/>
+

+🎉 That's all for modifying a hero's skin. Have fun with it.
