Help!
When I render my wood grain, it looks great close-up (i.e. 2000x1500
resolution) but it has ugly patterns in it at lower resolutions. Is
there some way to make the lower resolutions degrade more realistically?
I've included the POV files and a link to the JPGs in case someone could
take a look at it.

If this problem would take any substantial amount of time to fix, I'm
certainly willing to pay someone to help me with it.
Please help!
Thanks,

Antialiasing.

This was highly unnecessary. We have a group for binaries, and this
isn't it. Please cancel your post and repost the binary portion in the
right place.

I have found that rendering at >200% the final image size with +aa1 +r1
and resampling in image editor is faster and looks better than doing
full anti aliasing in pov.

I've tried numerous anti-aliasing parameters of the following form
+a +r3 +am1 +J
where I've varied the X in +aX.X and +rX and +amX and even -J and +JX
I still can't get the patterns (Moire ?) to go away. Can anyone recommend
particular anti-aliasing parameters to try. Someone suggested making the
image twice as big and letting an image editor sample it down, but that won't
be useful for my application. I need each rendering to work without any
post-processing.
Thanks,
David

+a0 +am1 +r3 -j

I recommend +j. This causes the samples to be jittered, which avoids the
moire artefacts caused by regular sampling.
