Here's my latest. Used Walli's fine grasses from NWDA and a couple of bushes and tree from Xfrog.
Rendertime was 4,5 hours @ detail 0.85, AA8 (adaptive 1/16th) and GI 1/3.
I think I'll make a new version with some more mosses on the fake stones.
Those mosses are actually a population of tiny grasses :)

very nice, I like the transition from green grass to the greenish water.
Great detail in the grasses and rocks. One complaint from me is that the water looks too tropical in its color. Maybe tone down the green and darken the blue a little?
Very nice image, Martin. I like the tiny wavelets and patches on the pool. The only problem I have are the grasses growing through the rocks. The rocks themselves are great.

Thanks Paul :)
Tropical? Nah...it's just clear rainwater as I've seen often here in The Netherlands.
In my opinion bluer water makes it look tropical.
There's a green surfacelayer following the water shader. It's an unsaturated green and has a coverage of 0.15.

Thanks :) You're absolutely right about those grasses. I'll see what I can do about it, whether I'll try to be lucky with seeds or make some masks.
Love the colour tones in this one Martin. The underwater features are also really nice and clear without being angular and fractalized. It surprises me that you were able to get them looking this good with only 0.85 detail. My only complaint is the colour of the little green bush in the background is a little jarring in contrast to the grasses.
I know you like to be a purist, but for your sanity it may be a little easier to simply get the seeding for the grasses close to perfect and then clone out any remaining problems after.
I encountered the same problem. There should really be a possibility to create a mask with increased 'spots' from the fake stone shader. I guess the stones are just locations (single XYZ) from which the stones 'erupt', but if you'd increase the space around each location, you'd have a good mask. The other way around would work perhaps. Using a fractal mask for the stones and a colour adjusted one for the grasses.
---Dune
It's a very tricky problem. With most masks you are probably going to end up with the grasses looking like a cultivated rock garden with everything precisely positioned instead of randomly growing out from under, up and around the rocks.
You're probably right. Perhaps paint it away (in TG or Photoshop would indeed be easier). But a mask derived from the fake stones distribution would be handy anyway, e.g. to have snow/sand pile up, or place the stones in depressions (sand blown out or mud 'watered' out).
Thanks Ryan :) I'm glad you like it and thanks for your input as well. You're right about the tone of that bush, it's a bit off.

Exactly! Which remembers me that O_b once made a shadernetwork which generates displacement around each fake stone. So there must be a way to mask them using function.
If I'm not mistaken I can buy it at NWDA CS for around just one buck :)
If that doesn't work or makes rendertimes horrible, then I'll just paint it away in PS. Oh man, how much do I hate that :) lol
nice shot Martin !
I don't like the very green water as it looks tropical on my screen (even if I read your statement about rainwater in Netherland ^^) and there is some of the grass that appear through the fake stones bt the overall aspect is nice.
I hope to see some next iteration soon, dude !
the grass colour is very realistic !

Shameless self-promotion :).
Thank Paul, that's indeed the shader I meant. Will try it out this weekend :)
Looking good! I really like the colors of the grasses and the stones, however IMO I think that the water's transparency is a bit too green for this environment. Really nice work here!
great shot Martin, I have seen many green things in NL, dijks, weeds etc! the water is not too off putting, though maybe cloudier would work better (for me)...the bright green plant is a bit harsh in my eye, that being said, I am only nitpicking! I like this alot !
Martin, just feed the last shader of your fake stones network into a merge shader. The second input for this merge shader will be your grass distribution shader. Merge method is highest.
Then use this new merge shader as the distribution shader for the grass population. I think this will work. I hope.
Regards
Frank
Very nice image , Martin :)
I have nothing much to add here , but one question ; the far left side of the water edge , is there some kind of problem ?
That seems interesting, Frank. Never thought of it. I'll give it a go. And O_B's shader would indeed be interesting as well.
Thanks guys :)

Always one step ahead of me :) Very good suggestion! Thanks :)
Although I didn't use a density shader for the grasses, I just created a distribution shader without any restrictions and fed that into the merge shader. I connected a color adjust after that to control the coverage a bit more. Works good!
Also, using this, I can selectively exclude different stone sizes if I'd like to.
Very clever!

Thanks :) I'm glad you noticed that, I missed it. Fixed it for the next version I will render this night.
Might take a bit longer since I ran into unknown bugs.

Does it really work good for you, Martin? Frank? I experimented a bit this morning, but wasn't very satisfied. Still had objects (little test sticks in this case) growing through rocks. I put a color adjust between the stone shader and merge input, a distribution shader+fractal into A, set it to highest, normal mix (I also tried others) @0.5, but still sticks out of rock. Played with gamma, black point and white point, which altered the distribution somewhat, but never completely away from the rocks. Perhaps it depends on the rock size as well, in case the stones 'erupt' from a certain (tiny) point. Then small stones would of course work better than large ones. I'll experiment a bit more...
---Dune
I think I have been a bit too enthusiastic by the first results Ulco, apologies.
I did a couple of small crops and those accidentially looked fine, but in overall it doesn't seem to really work.
I can see that the object count decreases when using this technique, but there indeed still sticking grasses through.
I've tried the exact same things you did, to no avail yet.
If I find a solution I'll let you (guys) know.
Martin
I would have thought 9 times out of 10 you don't want objects appearing through fake stones. Would it not be possible to fix this in Terragen so that the populater takes into account fake stones and doesn't place objects to that area, it could be a checkbox?
You've got me drooling with this one Martin! Absolute wow.
