Can someone explaine to me the huge difference with this pov when rendered
in 3.1 vs 3.5...I just dont get it...
I understand part of the problem is the change in the way normals are
handled, and I believe I can fix this by simply lowering the value of my
normals, but the part that really has me puzzled is the way the color map
has been displaced.  Could someone please explain the difference that is
causing it and how I can adjust for it with precision rather than inching it
around over a million renders to find the proper values...there has to be a
direct relation but I cannot find it!  Also, could someone explain the new
changes in Normals so that I can adjust my renderings appropriately.

Read about the noise changes in the manual.

BTW, this group is not for "help" but "bug reports".

This is of course truth but text at end of downloading page (windows) can
confuse: "Please report all bugs and problems in the povray.beta-test
newsgroup." His post contains his problem. Perhaps this text could be more
clear.

It does say

"Please be sure to read <http://news.povray.org/povray.beta-test/17912/>
before using the beta."

doesn't it?

It says feature requests are forbidden and how bug-report should look. It
doesn't say problems with adaptation are forbidden. It dosn't precise what is
off-topic to "beta-test" topic. He not sended feature request and he can
consider his problem as "on-topic". But of course he is "guilty" becouse of:
"please read or re-read the POV-Ray documentation for the feature you are
having problems with." Anyway this discussion breaks "Try to keep the off
topic chatter down to an absolute minimum." so EOT, sorry.

Okay, thanks, I was looking in the manual under pattern, and color map, but
I did not find the section about noise in my blind stumbling, thanks for at
least pointing me in the correct direction...
