Maybe the texture is a bit distracting? Looks good however; have you
tried to play with less translucency too?
Like with my tuit, I am a bit worried about sslt and text. I would like
some learned comments on that particularly.

Well, you aren't going to get anything learned from Stephen or me :-)

I already lost that hope indeed ;-) but there are those who keep their
learned knowledge jealously to themselves...

I agree but I just modified a texture that, that I liked, which I had made for
the RC4 SSLT. The original translucency was too high and the value here is a
tenth of what it was.
The colours are too dark for expensive jade and need to be lightened.

Indeed, I thought that I would try to sink the text into the body for a
comparison.

Your text seems to be almost placed on the cylinder and not a part of it. I
assume that you use a merge. Since my model has lots of differences, (I
differenced the basic model from a blank, to create a mould. Then differenced
that from another one to get rid of the internal structure.

I also sank the text into the body, both positioned at the origin for
the z-axis, and using a merge to get rid of the internal geometry. As
the geometry of the letters is much smaller than the tuit's object, I
concluded that they would need a smaller mm_per_unit value but I am not
sure if I am right with that assumption.

It's not because some details are small that you need to reduce mm_per_unit.
That value need to reflect the actual scalling of your scene.
The default of 10 mean that each pov unit is actualy 1cm whide.
Setting it to 1 mean that one unit is 1mm whide and a value of 25.4 is
good for a scene constructed in inches.

That assumption is absolutely...
... wrong :-P
Having two different mm_per_unit values wouldn't make any sense.

My explanation was ambiguous at best ;-) As the total object is a merge
of tuit + text, there is also only /one/ mm_per_unit value.
What I am struggling with is the /meaning/ of mm_per_unit. I am
understanding the sense of it but am unsure how to interpret it in a
scene. I need to ponder Alain's answer above a little longer, if my
brain accepts to fire up...
...so it doesn't matter what the /size/ of the object is as long as you
fix for yourself what a pov unit corresponds to in the scene. OK, fair
enough. In most of my scenes I have a clear idea about this. However, in
a test scene like this I just meddle around without clear notion about
true sizes. With sslt I should thus start with determining that beforehand.
Thanks! Much cleared now. I supposedly did not read the docs well enough
in the first place it seems.

Revisited the scene; set mm_to_unit to 10; scaled the tuit to be 3cm
across. Rendered with and without sslt.
