Filename * Does Not Adhere To File Naming Conventions

Typically the filename of normal map textures ends in *_n.dds.

The message indicates the possibility that the normal map filename has a typo or might be wrong. For example instead of an actual normal map texture a diffuse texture was defined.

It can mean the mod author does not care about standard naming conventions for better usability and compatibility.

Modding, searching, filtering, troubleshooting and tools, including xLODGen and DynDOLOD, work best and if everything adheres to Bethesda convention.
