# Jagged edges when using Glare in Compositor

I have designed this jewel:

I am using Compositing nodes for the final render, to add a glare effect, as such:

But the result is that some of the edges of the golden shape are irregular where the glare is most present:

I have tried to change the settings in the Compositing nodes, which didn't do anything, and I can't seem to find a way to make the edges as sharp as they should be.

• Can you upload your .blend file to Blend Exchange? – Shady Puck Aug 12 '16 at 1:24
• Is the render resolution set to 100%? Have you tried setting the quality in the glare node from medium to high? – user1853 Aug 12 '16 at 2:11
• @ShadyPuck I just added the .blend – MicroMachine Aug 14 '16 at 5:19
• @fabriced I must confess I don't really see anything obviously amiss in both circled regions.. What exactly are you looking for in terms of "sharpness"? – gandalf3 Aug 14 '16 at 5:32
• Unrelated, but I thought I'd mention that the alpha-over node in your setup isn't needed. If you want to mix between the original image and the glareified version, the mix setting on the glare node can be adjusted; -1 is the original unmodified input, 0 is the glare + input, and 1 is just the glare (and everything in-between is a mix). – gandalf3 Aug 14 '16 at 5:36
