Symptoms:
- I do not understand how the Anisotropic Textures field affects the Aniso Level for each of my textures.
- The anisotropic filtering for my textures is not what I expected.
Cause:
The Anisotropic Textures field (Edit > Project Settings > Quality > Anisotropic Textures) has the options Disabled, Per Texture, and Forced On. It can be confusing how this relates to each texture's Aniso Level exposed in the Texture Importer.
Resolution:
In the Texture Importer, an Aniso Level of 0 or 1 means disabled; higher values represent different Anisotropic filtering levels.

Anisotropic Textures (found within Quality settings) can be Disabled, Per Texture, or Forced On.
This is where Aniso Level 0 and 1 differ; 0 always means disabled, and 1 (and higher values) can be overridden by the setting in Quality settings. Forced On clamps the Aniso Level between 9 and 16 (unless a texture has Aniso Level set to 0, in which case it stays disabled for that texture).
