This is /not/ Islay although the scene was inspired by views from the 
island, so do not expect a shot of Lagavulin ;-)

Early wip, with height_field generated first by World Machine then by 
GeoControl. The cloudscape is a single df3 file created with Gilles 
Tran's MakeCloud macro. Parameters are chosen in such a way that not a 
single cloud is created but a scape of scattered clouds instead. This 
circumvents the danger of container artefacts that Gilles warns about 
when using several df3 containers scattered over the sky.

Were you thinking of me there? Whatever, I don't accept shots. A

Thanks. It was a new perspective for me into the use of Gilles' macro. 
It opens up a number of possibilities.

Next wip.

Added a background range; picked colours from a photograph of Islay to 
improve the vegetation textures; made some miscellaneous tweaks.

The white points are apparently generated by the finish of the landscape 
texture at water level. Seems to be some interaction with the water 
media. No reflections, only specular.

Does the background range reach above the clouds? That blackness at a 
about the center of the horizon looks somewhat strange...

The vegetation colours look believable (from my naive point of view - I 
never have visited the Inner Hebrides!).

Change the colour of the sand? ;-)
I may have mentioned before. You could colour the sand silver or golden 
that would not look out of place.

Yes, clouds hit the mountains. The bare rocks are dark brown and in 
shadows mostly, that why you see it as blackness maybe?

Don't take my word for it ;-) Never been there either.

Yes, the sand is no good and needs a serious overhaul.

Not to me :-) There is something fishy there that I do not understand. 
I'll keep investigating there although the water is pretty cold at this 
time of the year.

Yes, if you know that they should not be there. Then you can't stop 
noticing it. I'll pass over the fish remark and just say that the water 
is cold at any time of the year.

I seem to remember someone having a similar problem with the white spots
a few years ago, possibly on this very ng. I'll search my archives to
see if I can find the relevant thread.

Thanks to John for the song, and indeed, Stephen, the water does not

On to some more details now; there must be people living there...

Which part of Islay are we looking at? It is reminiscent of Loch Gruinart.

Just to prove that the sand in the Hebrides is as good as I say. :-)

There certainly will be sheep. In fact if you are lucky you might be 
able to pick up a set of horns that look as if they were a prop for a 
Satanic film. You might be able to find a Heilan Coo as well. People are 
a bit more problematic. Most of them were sent to America and Canada 
during the Highland Clearances.

Not Islay, John, not Islay, but the scene has indeed something in common 
with it. I shall probably go on in the same vein for the time being. Or 
maybe not. Nothing is certain yet.

The Heilan Coo would be nice although more difficult. There are 
different things to consider. Atmosphere is one and human imprint is 
another. I have a couple of ideas I want to pursue.

I recall one guy who had stray white dot artifacts all over his scenes; 
in the end it turned out that his AMD processor had suffered permanent 
damage from overheating. (Some time later, the very same guy complained 
about the very same type of artifacts again; it turned out that he had 
fried yet another CPU.)

But I don't think that's the issue here. The white dots are clearly 
limited to a particular feature of the scene (the surf); also, at the 
far bottom right we can see how the white more or less gradually blends 
into the dark blue of the lake, probably due to anti-aliasing. The 
overheat artifacts didn't behave that way.

My personal guess would be that the water surface texture isn't properly 
limited to the flat water region, but extends a bit up the beach slope.

Just a long shot. ;-)
My head hurts thinking about using a particle system or Poser hairs.

I look forward to seeing them.
You must write a tutorial on how you create your landscapes. I remember 
your experiments in Gancaloon. And you have certainly know how to do it.
This landscape is one that I recognise. I spent six days on a 
semi-submersible being towed down the west coast of Great Britain. (Pedant)
It certainly has the look of the Inner Hebrides.

I wait in anticipation.

And I deduce that I'm missing the point of your post... is there any, or

No white Colombian Marching Powder involved.

I was just replying to your deductions with a chain of my own.
I had just finished reading the article when your post reminded me of 
the doctor who diagnosed, that a friend had diabetes by the precipitated 
sugar crystals on his shoes. From splashes after he had gone to the 
toilet. (I don't think that it is a true story, actually.)

Sorry, but that is how my mind works.

Either the above or I just wanted to post the link. I enjoyed working it 
out.
The choice is there to be made.

Indeed. Only alternative is with image maps. I have a cow model so I

I shall consider it although the work is quite simple and random. I 
think the most important piece of work is texturing. I essentially work 
with code developed by Jaime. I shall put something together that might 
be comprehensive.

Strange isn't it? I just took one of my existing height_fields from my 
collection thinking it suitable for the Inner Hebrides purpose, and with 
appropriate texturing it looks like the Inner Hebrides. It is a 
look-alike effect.

It has disappeared with the new sand texture. Not really sure why 
though. It seems to me to be an offensive combination of normal and 
finish settings of the sand with backlighting.

It was Jaime.

Now that I think of it, a couple of years ago when I was shopping for a 
new computer, someone (not a POVer) warned me against AMDs, saying that 
(among other things) they produce more waste heat than Intel CPUs. 
However, at the time Jaime was having his problems, I don't know whether 
Intel was any better.

   That was me.... :) I fried two AMD athlons due to poor cooling.

Back then, I think the main problem with AMD processors was not so much 
the amount of heat generated, but that they didn't automatically 
throttle down when in danger of overheating. Don't know whether that is 
still the case.

Similar with me - it happened in January 2009, an Athlon 64 2800+, which 
then was replaced (costly!) by an Athlon 64 3500+! Yes... Khyberspace - 
like all Afghanistan - is a very dusty environment...

Currently, I run a hexa-core Athlon, each core an 3,857 GHz... when you 
do raytracing, CPUs are NEVER fast enough!

See you in Khyberspace!

I guess I was lucky with mine, after I finished the build I proceeded to 
install Windows (IIRC it was Win98) and it kept blue-screen and 
switching off about 2 mins into the install. After I repeated this a 
couple of times I decided to open up the case, and I found that the "Z" 
shaped bar that holds the heatsink down on the CPU had snapped in the 
middle and the heatsink (and fan) was hanging down not even touching the 
CPU. A quick fix (with a bit of track rod from a radio controlled car I 
had lying around) and miraculously it worked well for many years!

Somehow, the wall* in the forefront is cut short despite the spline

Stating the obvious, with spline:

* is the missing part at the start or the end of the spline ?
* some splines do not show the segment from first to second point, and
some neither do from penultimate to ultimate point
* is the key (value) for the range of points along the spline in anyway
negative for some points ?
* check the range vs number of points in spline (you could have 10
points between 0 and 1, yet the range would still be 0 to 1)

You really are capturing the atmosphere of those western islands.

One thing and I feel that I am always being over critical. Sorry.
The wall in these areas are generally of dry stone construction. The top 
layer is generally rounded. (Google "dry stone dyke")
Once you have sorted out the spline problem you might be able to add a 
single layer on top of the main part.

The castle is perfect.

Not the case here

I suspect the trouble is here. I have a spline made up of 18 components, 
Val_1 to Val_18 going from 0.00 to 1.70 in steps of 0.10. It looks like 
the spline stops at Val_11 with value 1.00. However, in the example 
given in the Docs, values higher than 1.00 (and lower than 0.00) are 
given. So, what's up?

I shall renumber the Val_n parameters to keep them within the 0.00-1.00 
range and see what happens. Still, I am confused where the documentation 
is concerned.

Thanks indeed. Just trying to assimilate the views and translate them to

If I want to go on with Blockwall, the dry stone construction is 
possible, except maybe for the top layer of vertical stone slabs. I 
might get into trouble with that.

Ah yes! Modelled in Silo, gradually adding disjointed wall segments 
towards the top, then roughing the wall surfaces so that the slope 
texture could get hold.

Hm. It is a huge effort of trial and error each time but using primary

Yes, of course. I use Cyan with an ambient of 1 for the default texture. 
So that anything that I have missed texturing shows up.
