Hi,

I have a mostly transparent leopard-pigment (turbulence 2, frequency 1.01)
on a cone which gives me some spots. When I render the scene in Megapov 0.5a
I get much less spots then in official Pov 3.1g (watcom-compile). I didn't
change anything (not even the version-setting) in the scene file, just  use
Megapov as renderer. Shouldn't it behave like offical Pov when the version
is set to 3.1?

If you ever use
    #version unofficial ...
in your scene, then you'll need to use
    #version official 3.1;
to get POV to switch back to the old noise.  Simply using
    #version 3.1;
will not be sufficient.

Interesting... with that indenting, my reply looks slightly like poetry.
Emphasis on "looks".  ;-)

But I did not use #version unofficial ... in this scene. I just started
megapov (windows) and it took the scenefile over from the official version.
Anyway ... I changed the frequency of the pigment and the result is as good
as the spots from the official version. I was just wondering what happened.

Thanks,

Marc-Hendrik

I really don't know.  It should have been the same.

From looking at the source code, the leopard pattern does not use noise3d at
all, so there should be no difference, no matter what #version is used.  The
"spotted" pattern does use noise3d, if this is the pattern you mean.
