If I set QualitySettings.antiAliasing, then it sets value on quality level that was selected with a mouse, i.e. grey line - “Simple” in the image below:

How do I set QualitySettings.antiAliasing for level that is selected as a Default value for some platform, i.e. green checkbox - “Fastest”?

I believe you need to change the quality level first as changing anti-aliasing through code changes it for the currently selected quality setting. You can change it with QualitySettings.SetQualityLevel, then set the anti-aliasing. Unfortunately I do not know how you can get hold of which level is the default level through code.

Exactly - there is no way to know which is default level through code. Otherwise, yes I could accomplish that ;) so API is incomplete as far as I'm aware.

Most likely because it is a setting only necessary at edit time and QualitySettings is a runtime class. There is no QualitySettingsEditor class (actually there is but it is a private class only available to Unity) to edit the default settings through.

 –

@GameVortex, exactly again :) I need it for Edit time, to suppress "AA is enabled" warning when building AssetBundles...

 –

Good to know. I guess it's even possible to read it using SerializedObject and iterate through properties. Although I hoped I missed something and there is API for that :) I'll just hack something for now until they fix issues related to these QualitySettings

 –

Well, theoretically yes, if you could ever get the reference to the serializedObject at all. QualitySettings is a static class and never returns any object you could use reflection on.

Check out these links. It should be everything you need for this.

This is not helpful. See the answer by @GameVortex. We both agree that API is incomplete, so no - not everything I need is in the links that you have provided.

What's missing except ability to determine the default?

 –

When you can not get/set default you can not set it on the right one, when building AssetBundles (QualitySettings have impact on building of AssetBundles, unfotunatelly). I guess you're right - QualitySettings is designed for runtime, but that's exactly my point there is no API in editor to do what I need.

 –

Indeed it appears that the editor quality settings are just something of pre-defined macros.

Unity is confused by this thing itself :) If you uncheck one of the quality settings from a list and build Standalone application, then you're default selection will be shifted by one ;) ...also "mouse selection" (i.e. grey line) is used as a default for Standalone build, which baffles me...
