Setting antialiasing with python?

I know you can set Anisotropic filtering, but what about multisamples?

Edit: was thinking about textures settings dont know about world*

There must be some way to set AA samples. That’s very important if devs want to release their game to many people. Not everyone can have it at 16 samples. Are we supposed to just make different versions of the same game, each having a different level of sampling?? That’s not good.

Why dont you just use 2D Filter instead of python?

Well… I don’t know how, and I don’t know why you would. Is that how other game engines do it? I’m ignorant on these things.
