ProblemEdit
Some textures in the game appear blurry.
Cause - Missing MipmapsEdit
This problem is a result of a texture not having mipmaps, which allow it to be viewed at various sizes with less degradation in quality.
Solution: Change Texture Size to 'Large' in Video setting (via the ESC menu).
Solution: Notify the modder and ask him or her to re-save the file with mipmaps, or open the file in an image/photo editor (i.e., GIMP or Paint.NET) and re-save the file with the generate mipmaps option checked.
