Well, you could try rendering at four times your desired resolution, 
applying a 4x4 smoothing filter then downsampling using an image editor.  
Slow, but in all likelyhood it will work.

Give us some source. The camera, light, and a plane with that texture giving
you problems would do.

Massive antialiase jittering?

  Hmmmm... focal blur? I've not tested it, but I seem to remember Suzuky 
saying he used focal blur to avoid moire patterns in one of his latest 
posts.

  Search these newsgroups for the recent trick on blurred reflection 
developed by Ron Parker and others. It's great!

Sounds painfull.. I think I'll save this for the last desperate trace when
all else has failed. But thanks anyway.

Well, there's you're problem! This sort of pattern will quickly develop
moire! :) Use something like bumps. Or better yet, use Ron's blurred
reflection trick. I'll go whip up a version of this using his technique and
post it for you.

I hope this does what you want. I didn't make it super-smooth because I
figured you wanted a little graininess.

Well, I kinda know that. I want to get rid of moire not the texture. :) That
kind of quadrangular bump pattern is on my kitchen counter.
I have already tried the blurred reflection trick on the sinks, but it's
sooo sloooow.

But thanks for your effort!
