Blender box sharping filter. Help

I use a bit of box sharpening in compositor for my architectural visuals.
Where I use emmission the edges of the object become very black and pixelated.
Can anyone point me to a compositor node tree that I can extract so that the box sharpening can affect the emission pass.

Now I am showing a strong exaggeration so you can understand better.
Thank You :slightly_smiling_face:

What up

Sorry, I didn’t quite understand what you meant, but here’s what I’ve just found:

Hope it helps

I was able to slightly, but only slightly, improve the result by making sure what went into the filter was properly clamped between black and white. But in the end I gave up. As far as I know there is no equivalent to Krita/Photoshop/Whatever unsharp mask in Blender. Which I typically apply twice for high quality renders; once on 16b 4k output from Blender, and again for final 8b 2k output media. I can’t even rescale the image down in Blender - wish there was a way to do proper supersampling (to keep sharpness and prevent loss of details from the denoiser) automatically.
