Improving Post-Processing Anti-aliasing in URP

Unity Engine

I’m finding that the anti-aliasing on post-processing effects (like the bloom on the line renderer shown below) in URP is quite unsatisfactory. I’ve tried using both SMAA and FXAA but they both produce very little improvement. I have MSAA set to 8x, but I believe that this doesn’t change HDR effects.

I’m using the volume component, as it is my understanding that URP does not support the post-processing layer and post-processing volume that HDRP supports (and adding them to my project does nothing).

The only way I’ve managed to improve this is to increase the render scale. I’d rather like to avoid this, however.

Am I apply the post-processing effects wrong? Am I meant to be using different components? Is there any way to get a better result?

I don’t think there’s much you can do. We Need Temporal Anti aliasing for URP.
