file tested: crackle1.pov (in 3.7 include textures/patterns)
Artefacts vary chaotically under the parameters of the pigment/normal.

I have run into these artifacts as well. I'm using beta 30. Here's some
more code:
camera{
orthographic
location y*10
look_at 0
right x up y
}
plane{
y,0
pigment{crackle scale .05}
finish{ambient 1}
}
I suppose I should have written a bug report. Thanks Carlos ;)

When I was little someone called me "Don Carlos", but unfortunately the "Don"
and the "s" does not suit me, because unfortunately I am Italian.

Could some folks please try:
http://www.povray.org/temp/pvengine32-sse2.zip
and check for (a) crackle problems, and (b) crackle speed compared with
past versions?
thanks,

We can have the standard 32-bit?
Currently I have a cpu dated.
Thanks

Thanks for putting this one out to test.
It *looks* fixed, for me anyhow in the few ways I tried it.
Render speed is another matter. Without AA the two seem similar enough until
AA is applied and then I get a multiple longer render time. Like a 4X or 5X
change when just using crackle pigment and normal without any other
parameters (no solid, metric, offset), although different types of crackle
are also similar in this difference in render times if using AA versus
without.
Hopefully this doesn't mean antialiased crackle-containing renders will
always be slow considering how the broken version could be so fast. Wish I
had a clue why so I could help figure it out. Got to be something
interesting going on with it.

I should also mention, now that I've checked, that number of threads makes a
difference as well.
Much closer comparison if using only one thread instead of two, being 125%
render time (slower) of the current beta compared to the test version while
AA is on (default).
Please keep in mind this is only after a short time trying it in a very
simple test scene: primitives on plane, all using same crackle pigment and
normal.
Whether or not this is related to other one/two work threads slowdowns I've
had happen is something I can't guess about, of course. Would be great if
you, Chris, or somebody could discover if a problem exists with these
programming thread bugaboos. Of course, I still consider being able to use
more than 1 thread a luxury not a necessity... and it usually helps to use
+WT2 with my dual core CPU anyway for most renders, so I'm not going to
complain.

Stbenge, can you kindly confirm the defeat of the "crackle problem"?
thanks,

A "compromise", Don Carlo, actually sounds cool. And with "Don" I don't
mean the Spanish "sir" title, but the English name (as in Don Johnson).
