I modeled the chess pieces, but they all have a material with
rgb<1,1,1,1,1>...really!

...

Ok, I didn't really model any chess pieces.  Does anybody
have a nice set I could borrow (.mdl format)?

I've only done these three sorts of pieces.
When all will be arrived, I'll post them
on binaries-scenesfiles.

but... but... suspicious expression after rgb :-)

it is not easy - I have rendered scene with rgbft 1 and rgbt 1 and results are
different. second version trace correct but should both imo. I wonder it is my
misunderstand or candidate for beta-test report.

Of course - the filter value is different.

It is a misunderstanding if you think that they should render the same way.

When filter + transmit > 1 you should expect strange results. Look in the
documentation.

Thanks for clarification but now I must believe you. I can't find any note about
it within beta 8 documentation. I've checked 9.1.2, 6.1.5, 3.7.1.4. Perhaps I
missed some sentence. But... such combination (filter + transmit > 1) is used
within sample file as fog and it doesn't look strange.

Although in this case, assuming the chess pieces have the default black
pigment, filter contributes nothing and it'd be the same as "rgbt 1".

Not in .mdl (just plain POV), but there are some good models of chess pieces
in the scenes\advanced\glasschess\chesspiece1.inc in the POV 3.5b8 dir.
The object names are in Dutch, but the comments are in English, so you
should be able to understand which is which.
