Different settings for anisotropic filtering are confusing

0 is the point of confusion:

1. In the editor you can set it from 0-9

2. per script:
http://docs.unity3d.com/ScriptReference/Texture-anisoLevel.html

"The value range of this variable goes from 1 to 9, where 1 equals no filtering applied and 9 equals full filtering applied."

3. per script for force mode:
http://docs.unity3d.com/ScriptReference/Texture.SetGlobalAnisotropicFilteringLimits.html

"ForcedMin value controls the minimal anisotropy level set when Anisotropy is forced. globalMax value controls the max possible anisotropy level. set any to -1 to use default values." <-- that sounds a lot like 0 is a valid setting.

What is setting it to 0 in the editor good for? Why is that possible at all?

 

Another awesome example of the manual:

http://docs.unity3d.com/ScriptReference/RenderTexture-antiAliasing.html

"The antialiasing level for the RenderTexture.
The value is specified as a power of two (0, 1, 2, 4 or 8) indicating the number of multisamples per pixel."

real life result of setting it to 0:

Invalid antiAliasing value (must be 1, 2, 4 or 8)
UnityEngine.RenderTexture:set_antiAliasing(Int32)


Let me quote something:
"In theory, the Asset Store saves $1.4 billion in labor costs to the industry each year."

Now imagine the manual would be correct, that would save even more than $1.4 billion. EACH mistake of the manual will in worst case be multiplied by the 1.4? million users of unity - that results in a huge amount of hours which is worth a giant amount of money. And it is much easier to fix the manual than anything else.

 

Sorry to bump this, but this is still a problem in the latest online documentation for Texture.anisoLevel. It says that there are 1-9 levels of aniso when the texture import inspector clearly states 0-16. Where 0 is actually off and 1 is on. Also it should be noted that aniso only really works when mipmaps are enabled so maybe the inspector should disable it or the documentation should mention it.

 

I see, thank you for updating the docs with this information.

 

Sorry to revive this but there is still a disparity between the editor and the API regarding anisoLevel in the 5.6 docs. The API states values 1-9 are valid while the Texture inspector is a slider from 0-16. https://docs.unity3d.com/ScriptReference/Texture-anisoLevel.html
