I'd better make a new post. Did another one with the rocks and sand, and another go at a beach scene. The latter is quite promising, IMO, but needs work. The thing that pissed me off most was the time it took for a layer of RT reflection on sand and a water layer above that. All these reflections going up and down had to be computed, took 4 hours on an i7. I have to find a way to not use RT reflection on the wettest sand, and fake it by double reflection and a blue sheen, or something..... that's for later.
In the first one there are still highlights under water, which I later took out by a min height control. I had to give the rocks and sand two separate 'layers' of reflective wet edge, didn't work in one go at the end of the line, somehow.
Damn u are good! ;)
How the hell did u do the foam on the water :o :o
You know what I think of most Ulco? How is it possible to make the shoreline that smooth. I never really needed it so far, but my various experiments always give me some nasty rock-like bumps where there should only be wet flat sand! I believe there are some visible here as well. How do you do it? In my case even large smooth values don't work real well. >:(
Use a surface shader or a distribution shader to control the height and slope of the beach distribution shaders. Dune impressive work -those foamy fans of water on the beach are superb.
Really excellent - the subtleties in the sand in the last one are wonderful; very realistic!
Really impressive work, especially the third one!
Wow, on the third one. Sand and water are amazing.
I like Image No. 2
I pick...1, 2, and 3! More fine images to add to your impressive portfolio, really sweet work.
Nice images Ulco :)
I like the sand part under the water in the second image the most.
Loving pic three's foam and shore details. Others are great too.
The 2nd is the best
Those are all great, but I like #2 the best as well.

Third image for me. Just spectacular what you have going on here.
What a shoreline! Fantastic! How did you do that? The second one is great too. Especially the underwater part.
Hi Dune,
can you please show me, how i can do the Beach and foamy with TG2 ? do i need plugin for that ? or juste some settings ?
thanks.
wow, dune these really, really good :)
the foam on the third render looks pretty much spot on.
Been away for the week to 'study waves and foam' on one of our islands. Next one will be a lot better. I just need a way to circumvent 2 RT-reflective shaders interacting, as that really explodes render time.
If you want a smooth beach, you just start with the basic planet, and mask from there. Deepen the seabed to the east, and raise the beach to the west, and have the dunes 30 odd meters away from the waterline. This is all based on a get position in texture, an x to scalar, and then a lot of smooth steps where you can set the hard or soft edges, transform or warp them. But you can also do this with a set of simple shapes (and merge shaders). And all these masks can be used for the beach (planet) or the water (lake or plane).
If Spock were a real person, I'd fly him and I over to your neck of the woods and have him do a mind-meld with you and I. Super creations here Ulco; and, more inspirations. Your conveyance of enthusiasm is infectious.
Thanks Bob. There's so much possible in TG, but it's not all easy, I must admit.
Second version. With only transparent water in the front 100m. I don't like the way the clouds are reflected in the waves, it makes the water very speckled. And I need to work on the foam and dry sand areas. The wet sand is a no-RT reflective shader, as RT takes ages. If I can find a way to mask the wet sand out exactly where the water layer is, that might help....
This is impressive of realism. Once you have adjust the foam it will be just like a photo.
The last one is insanely realistic! This is imho the best shore image made with TG ever. Maybe the foam is a bit too noisy, but otherwise 98% photorealistic.
Agree with Hannes. As was in Terragen Classic, it would be good to have a plug in to create shore foam with TG3.
Looks great Ulco :)
Next iteration, different setup.
come back otherwise a girl will cry ;)
Poor teddy bear...
That foam on the last image is absolutely convincing. Anyway I liked the more pronounced wet/moisture areas on the sand of the previous image.
Definately the best beach scene produced in TG!
The image and especially the foam looks great!
Ulco, I'd really love to know how you made these overlaying foam patterns, where the waves hit the sand. And of course if this is animatable (is there a drooling smiley?)
super surf/shore interaction... truly the best shoreline in TG?
cheers

:)
Beautifull !!!!! :)
Agree, the best shore foam and white caps on the waves I've seen.
I explained before that I work with masks a lot (one hard end plus one soft end (you can base that on simple shape combi or the get position in texture+ x to scalar + some smooth steps), the soft end broken up by voronoi PF), so every mask can be applied to a different surface shader, making a stack of them in the water line. And if you transform each incoming mask (move it lengthwise along the coast) you get different patterns overlapping.
Time to experiment, guys!
Really starting to come together nicely.

Oh yes, these are getting real good.
The teddy bear is just funny! ;D
From far away (last image), there is no way to tell whether than beach is real or generated. Way to go, man!
Impressive as always Ulco
That v3-5 is super!
You're getting closer and closer. 8)
Not close enough yet? Any improvements suggested?
The surf is awesome,but my brain can't decide if that's ground fog or dry sand
on the beach,seriously.
Ah, good that you mention it. I have to remove that perhaps; it's dry sand, but I agree it's not good enough.
You've got the area where the water meets the shore to excellent standard. The small waves and foam and wet beach. Bigger waves further out is a much harder thing to achieve. I'm not sure how you'd get that truly realistic but with more subdued larger waves you'd have a totally convincing effect. I think with the waves you have, the effect where it meets the beach would be more violent but that would be extremely difficult to sort out.
One thought I have is that waves tend to build up or get rougher towards the shore. I think it would look more realistic if in the distance the waves were less rough.
The foam and the wet shore are outstanding.
