Unity 4.2 supports anti-aliasing on render targets
Just noticed in the release notes that the recent Unity 4.2 release finally supports anti-aliasing on render targets! Might be a big quality boost for demos running native resolution.. downloading ...
I want to point out a potential issue when using MSAA on RenderTargets.
Both dynamic lighting and shadow buffers are tightly coupled with the Camera itself. I have noticed that when I use a RenderTarget of a larger size then the final output (which is 1/2 the size of the final screen size, say 640 x 800), the buffers used to accumulate lighting and shadow stay the same size. This has the effect of dynamic lights and shadows 'clipping' against a plane smaller then the final buffer.
The engineers at Unity are aware of this, but please keep this in mind when using larger Render Targets to get a better resolution output. In Tuscany demo in the SDK as well as in Unreal, the output looks better because of the fact that we can MSAA into a larger render texture and then down-sample into the final target (which is the intention of this new render target feature). If you do not use dynamic lights / shadows, you will achieve the same results as this.
We will include MSAA support with the above caveat in the next Unity integration release.
