Nice. This might be the best of your many landscapes so far.

Yeah, those mountains really look very good. Do we get the source as a Christmas
present ;)

Nice.
I just found and downloaded the new version of lightsys. Any idea why it
doesn't work with MegaPOV1.0 ? It works with POV3.5 !
Yesterday I played with the skylight macro (apparently an older version from
this news archieve) but I ran into many problems with light intensity. The
sky around the sun couldn't get bright enough to give correct reflections.
Has this issue been addressed?
Regards,
Hugo

Very nice image, Christoph. Excellent for a quick christmas card,
indeed. No snow around here to check realism, sorry... :)
> The sky is made with the skylight macro from Jaime's lightsys:
To be honest, this version of skylight.inc is the work of Philippe
Debar, adapted by Ive to work with Lightsys: I even don't remember if I
myself done any little teaking...
I don't know if the results are very accurate, but it gives slighty
nicer results than the original version.

How? ...what's the error? I can't figure why it will not work (I
don't have MegaPOV right now to test).

Hmmm... I think the answer is no, but try yourself, please.

Glad to see you stopped by! The updated lightsys is great! The bug is a bit
difficult for me to track down. The error message prevents all your demos /
templates / tests to parse. I have 4 versions of POV-Ray installed. They all
claim to be based on the POV3.5 source, but your macros only work in 2
versions:
Official POV3.5 = works.
Unofficial MLpov 0.81 = works.
Unofficial POVman 1.0 = breaks.
Unofficial MegaPOV1.0 = breaks.
Here's an example of the error message:
File: demo_cyndi_cubes.pov Line: 38
#declare LC1 = EmissiveSpectrum(ES_Osram_CoolFluor_36w) <----ERROR
Parse Error: Expected '( or [', ) found instead
Returned from renderer with error status
When I add () it complains that no value was found in between the
parantheses. When I write (1) it breaks the macros. Maybe it has something
to do with splines, since "ES_Osram_CoolFluor_36w" refer to a spline...(?)
Best regards,
Hugo

Yes, there is known problem of spline being parameter. It is fixed for next
release, meantime try to add spline{} around ES_Osram_CoolFluor_36w. It should
help. Sorry for inconvenience.

Thanks.
The snow is indeed the weak point - i played with the idea of a
subsurface scattering version but this scene is not fast enough and the
geometry is not that good to show the scattering anyway.

The problem i have with the skylight macro is that it does not offer
much control over the colors. I used a different light color for the
sky than for the light source to have more freedom in that part.
Another thing is of course that the use of a mesh for the sky is
certainly not the best solution - although it is of course the only
viable one with standard POV. A feature to have image_maps based on an
internal array (or an ascii hdr file format) would be useful for this.

The mountains are actually quite simple, the structure is made with a
f_ridged_mf() function and the coloring with a slope pattern. I posted
examples for this in the past:
