+## Texture import normalization
+
+Texture import settings are cached in `.import` sidecars. To keep new textures
+consistent by default, normalize imported textures before committing:
+
+```sh
+./scripts/normalize_texture_profiles.sh
+```
+
+To normalize only a specific directory (for example environment textures):
+
+```sh
+./scripts/normalize_texture_profiles.sh res://art/exported/environment/textures
+```
+
+The script enforces a single baseline texture profile by default and sets
+`import_profile = "managed_default"` in `[params]`. If any texture needs
+custom settings, set:
+
+```ini
+[params]
+import_profile="custom"
+```
+
+in its `.import` file to opt it out.
