public int antiAliasing ;


The antialiasing level for the RenderTexture.

Anti-aliasing value must be one of (1, 2, 4 or 8), indicating the number of samples per pixel.

When a RenderTexture is using anti-aliasing, then any rendering into it will happen into the multi-sampled texture, which will be "resolved" into a regular texture when switching to another render target. To the rest of the system only this "resolved" surface is visible.
