@@ -17,6 +17,7 @@ See `checks/` for a detailed list of checks and reasonings. In summary:
  - **Is Binary**: Verifies the file is saved in the FBX Binary format. (Blender can't open ASCII files)
  - **Bounding Box**: Verifies any given mesh is not massive or tiny. This can cause "Generate Lightmap UVs" in Unity to fail.
  - **No Scale Compensation**: Maya animations use Scale Compensation by default. Unity (or any other tool) doesn't support this attribute.
+ - **No Namespaces**: Requires all model names to be exported without namespaces.
 
 ## Usage
