And here is a first view of the logo with triplanar mapping (and other 
background changes).

Still wip scene of course...

(could that device be Hawkwind's long sought for "Orgone Accumulator" ?)

Thanks! I am very happy to have triplanar mapping available within 
POV-Ray now. Could solve some issues I had in the past.

LOL yes, might well be indeed...

[now playing: Hawkwind - "Orgone Accumulator" from Space Ritual album]

...ancient memories... ;-)

It's coming right along! I like the idea of the moon-textured P exterior around
the planet.

I forgot to mention it (and you probably already know this), but triplanar
mapping doesn't play well with hard edges. I can't really see a problem in your
image due to the shadows on the inside of the round shape, but discontinuities
are likely there.

Thanks Sam, yes, this triplanar mapping is what was needed here. 
Different little ideas I got at night while not sleeping I want to 
try/implement into the next version.

No problem here and, possibly, not even a real problem if visible: I can 
imagine that craters would not line-up over hard edges like here. I have 
not decided yet if the inside of the crescent should not get a different 
texture though...

What is it with not being able to sleep as well over time? Less endogenous
melatonin?

Right, that makes sense. The only way that would happen is if the impacts blew
holes through the edges, but making that work wouldn't be easy...

Like what? Something half molten? Or crumbly?

Oh no! nothing as dramatic! :-) I sleep very well indeed (eight to nine 
hours on an average night) which, at my age, is rather exceptional. 
However, and I think that many experience the same, I may wake up at 
night with an idea/solution for something I have been working on during 
the previous day(s).

Correct, but I am not modelling the Real World, as you probably may have 
noticed by now... :-)

Not sure yet. The ideas are in flux...

A very nice improvement of the scene, Thomas!
Just a question: the detail of the planet seems different respect the 
detail of the rusted P of the logo. Is it intended?

Totally different textures and, I should say, totally different 
modelling. The planet is Sam Benge's work: RidgedMFPlanetB.pov in his 
post here "Ridged Multifractal Planet", in October 2023.
