   Nice improvements: the textures are way better. But I see something
weird with the checkered floor: looks like if the normal doesn't matches
the lighting. Also, the gap between tiles on the inside floor looks like
too big.

   Oh, and that nice cluster is really begging for a more dramatic
lighting (I think Radiosity_OutdoorHQ from rad_def.inc will do the job).

I have been wondering about that too. Only light source is the Sun, 
shining directly into the cloister, and reflected from the outside on 
the left side of the image, which is open to a garden in my model. The 
normals seem indeed strange. The bump map is a blurred b/w image where 
black is the gap + bevelling of the tiles and white the tiles 
themselves; bump_size=10.

It seems counter-intuitive to me, but inverting the bump_size seems to 
give the correct result (see image). Somehow, this is the inverse of 
what I /read/ or /understand/ from what is said in Poseray.

That is right. At first I interpreted it as a extra decoration, but 
better would be to reduce the gap.

I'll try that indeed.

   I remembered now that this happened to me once, and the problem was
that the mesh was inverted... maybe that's the case?

No, the true problem is that POV-Ray has been doing bump maps wrong for 
ages, and it's somewhat random whether a positive or negative bump_size 
gives you the desired results... or neither of them: There are cases 
where the bumps look like the light would be coming from 90 degrees off 
the true light direction.

This isn't trivial to fix, and although it kind of has been the first 
item on my todo list ever, this probably requires some custom-tooled 
heavy duty mil-spec tuits.

Good to know. Somehow, I prefer this case otherwise I was beginning to 
doubt the wiring of my brain cells

Those are difficult to get at this moment...

Rubbish! I've still got a warehouse full of them. Everything from
kindergarten class tidy-your-room-up tuits to the full monty.
Send me your specs and I'll despatch a few at no charge.

Ha! That's what they say! 'no charge', and then the bill falling on the mat!

Dump a cratefull of full monties on Christoph, please.

Turns out they need to be those space-grade hyperspace-jump-capable ones 
- I've just installed Frontier's Elite: Dangerous beta. Hard times for 
you, folks - fun times for me :-D

(The Thrustmaster HOTAS Warthog combo + rudder pedals really kick ass 
with this game. Pity I don't own an Oculus Rift as well...)

I've been lost there for the past couple of weeks.

You would have to be prized out for your meals. ;-)

I left the old school behind and bought a joystick.

How about meeting up in there some time? Cmdr. Apec Valorian would be 
glad to accompany you for whatever it is you're currently doing.

What's "old school" about /not/ using a joystick when it comes to Elite? ?-)
