I know that unity iphone currently does not support anti-aliasing. Until recently, I have just assumed that this was a limitation of the hardware. However, recently I have seen games that feature anti-aliased 3d. Granted, it is only 2x, but it is certainly better than nothing.
Has anyone looked into possible workarounds for 3D anti-aliasing in Unity? I'd be curious to see methods as well as performance implications of better edge rendering.
