Question about project-wide MSAA vs. Shapes local AA
Looking at the Shapes Feature Table, I can see that basically every 2D shape but polygons support local AA. I can make polygons look nice by enabling the URP's MSAA (4x or 8x looks good). When doing that, does that mean the renderer tries to anti-alias my already locally anti-aliased shapes again or only the shapes that don't support local AA?
Thanks.

Shapes are rendered the same way regardless of whether MSAA is enabled or not, so it would do two rounds of anti-aliasing on it. That said, I don't think it would degrade the quality at all, if anything it should look pretty much identical! worst case you'd just be paying a minor cost of rendering the LAA rather than not, but I don't think it's a big cost. You'd have to test it on your target platform to know for sure!
