 1. Have `habmodules` and `shipbuildericons` files in `./resources` folder. You can find them at `C:\Program Files (x86)\Steam\steamapps\common\Terra Invicta\TerraInvicta_Data\StreamingAssets\AssetBundles`
 2. run
     ```bash
-    rm -rf ./public/icons/habmodules/ ./public/icons/`shipbuildericons`
+    rm -rf ./public/icons/habmodules/ ./public/icons/shipbuildericons
 
-    python scripts/export_unity_textures.py ./resources ./icons
+    python scripts/export_unity_textures.py ./resources ./public/icons
     ```
 
-I am currently using icons from the experimental branch, it should be working fine. If it's not then fix it (like keep two separate icons sets maybe?). For now seems excessive.
