Bad antialiasing between light and geometry.

How to get rid of aliasing in the edge of light?

I have read joconnell's tutorial of float images.

I do understand what he was writing and why
antialiasing calculations can't do the job as supposed to.
He said that using clamp output should correct this, but
I can't see any difference.

Any advices? What filter could work best?

what AA filter are you using? you need to be careful using sharpening filters like catmul rom

[LarsSonparsson]

well, at this time I'm using Cook variable 2.5. It's almost like
area filtering - not sharpening edges.

And non of AA methods works better - subdivision, fix or QMC.
Maybe I just need to do it in post.
