Sorry, double made ;-) Thanks dear Studio, I will check it at the end of the week. I have still two other projects until I can proof my shader and vsl material according to the water textures! :-)) have a nice week and good luck further for your projects! :-) See you and compliment for your engaged work also with the ligth+env.map tutorials :-) Servus, Frank Brübach, Germany

Betreff: Re: Question for a water vsl shader
Hi Frankolino :
OK , sounds like quite a comprehensive task that you're aiming
for , but that's good ! I know you will share your results when
you're finished and I'm looking forward to seeing your results .

Karl mentioned the 'cellular' VSL object that you have discovered
and it has been a standard of sorts , in other 3D S/W's for those
nice , sharp looking sea waves .
Here's a link to an awesome image by a master POV god , Gilles
Trans . Posted here earlier during the lengthy "clouds thread" .

You can easily see the cellular shape and the hard edges of
the cells caused by h2o's cohesive properties (surface tension).
This nice sea water also has a tiny bit of noise introduced for
more surface realism too . No luck for me with RS and cellular .
Here's a sea water I did with V3.53 before we had multiple
noises , and is just a small noise and a bigger noise combined
and of course stretched to give more realistic elongated waves.
(it's a 10 year old render, so please forgive the hard shadow)

Karl also mentioned that his 'Noise_controller' vsl shader is
a kind of all-or-nothing noise , with hard boundaries between one
area and another . Here is an extreme example of that ...

... and a much noiser example that blurs those boundaries ;

Anyway , long winded way of saying , as usual , many options,
of course , but as far as I know you will be on the bleeding edge
creating a nice wavy sea-surface type of material using RS3D .
I myself have spent some time with the 'Cellular' vsl object ,
and added a little noise , but it did not look very good, for me .
I used displacement mappings and tried all different settings but
could not hit that magic mark , but maybe you could , with your
new computer that you most definitely will need for the hundreds
of test renders that are coming your way .
However , I did have a little more luck just using the RS3D
'wrinkled' material (simple noise based shader) & modified sett-
ings (example project attached) .
Applyied as a rectangular shape to an nurbs rectangle , it
didn't offer those nice sharp edges like cellular might but it
did not look too bad and with a little small scale noise added
I think it could _possibly_ do nicely for sea-swells at least .
Good Luck with your work !
