I've just been suffering similar problems with heightfields to those Gillles
has recently mentioned.

Is there any hope of a fix - perhaps in the next version of megapov?

Yes.  I'm interested to see if people compain about it 'breaking' old
scenes, or if nobody will notice that.

Hooray!!  I bet the biggest problem will be old sky pigments.

Is there an ETA for version 0.5??

What is this "plateau-free noise"?

Thanks.

Fabian.

Whoohoo!

For the record,
    #declare shouting_tone=true;
       PLATEAUS BROKE SCENES,  REMOVING PLATEAUS WILL FIX THEM!
    #declare shouting_tone=false;

Can't wait for 0.5!

  AFAIK it's the following:
  The fractal noise function used by, for example, the bozo pattern should
return values between 0 and 1, but instead it returns values that are outside
that range (0 and 1.5 or something like that). This value gets then clamped
to the range 0 - 1 (ie. all values greater than 1 are converted to 1).
  This causes flat areas of height 1 in the bozo pattern.

):5;i&&_>1;printf("%s",_-70?_&1?"[]":" ":(_=0,"\n")),_/=2);} /*- Warp -*/

Look at my image at povray.binaries.images:

    Subject:
            In search of plateau-free noise (28 + 32kbbu)

In a "fixed" noise3d, there would not be plateaus.
