Seems like i'm seriously creating an image atm.
As there is already some snow again on the alps, i'm getting nervous and all exited. :D
Just a few more weeks!!!
My plan is to add some trees in the lower valley and to use a cloud for some powder-like effects.
A motion blur will be done later in gimp.
the more blue image is what came out of tg2, the postworked what i want it to look like later; it should look like the view trough ski-glasses.
all comments and suggestions welcome!
edit: shame on me! what i totally forgot to mention is that the snow is partly dandelO's plain snow shader. thx man!
ok, i tweaked the snow and rock surface a little bit.
The snowboard is gone for now, as its the last thing i will add - every change of the surface will otherwise make it fly or eat it.
i don't know if i like the overhanging snow; i've often seen this, but it looks strange here.
also i think the patch size needs to be way smaller, as you can see edges in the snow. :/
Looking very good. I like the overhanging snow but I agree, it needs some work, its a little too uniform atm.
Its diferent but your image reminds me of this ... wing suit (http://www.youtube.com/watch?v=ttz5oPpF1Js) or Speed flying (http://www.youtube.com/watch?v=UwWLnaME0CI&feature=player_embedded#!)
Are you going to animate this?
Richard
i think a redirect should do it; i'll see what i can get with that.
sadly, i dont have the deep+animation version, just the deep. but it would be a good candidate. this image was rendered in ~8 min with 0.8 detail, 3 AA, supersampled 2;2 gi and raytraced shadows on my core 2 quad.
maybe the animation will be my xmas present to myself this year. :)
thx,
Goms
Cool snow :) Blue-node magic or "normal" shaders? ;) You can get similar effects with intersect underlying, but I haven't seen anything like this before.

Looks like a fair rendertime to me. Don't forget that you'll need detail blending enabled for animations. You'd also need more GI samples to avoid flickering.
In my experience so far a sampling level of 6 works fine.
For clouds it's also best to have acceleration caches disabled. So if you plan to add those, remember that.
So with this in mind, I guess the 8 minutes/frame will likely become 20-25 min/frame.
Looking forward to where you're going with this.

all normal shaders until now. ;)
i used the favour depression intersection with very detailed settings; wasn't easy to figure out the right values.
the breakup of the snow was pretty easy btw; i just added a fractal before the compute terrain.
This breaks up the smooth surface of the heightmap.
as you mention it, what exactly are detail blending and displacement filter doing anyway?
most of the options in the extra tab are mysterious for me :D
next update. the snow is a little bit tweaked and the light changed.
I don't know what to do about the sun settings. i get the most out of the rock structures with a light from the front and low elevation...
but this makes the snow just plain white. :/

And unfortunately, that's the only way you'll see the 'sparkle' function, if it is indeed enabled in the snow shader. It relies on a direct front light as it is a simple reflective Perlin function.
A secondary sunlight in front, with only 'specular highlights' checked will do the trick to maintain the sparkle whilst you move the main sun around the scene.
It's nice, the way you've rounded off the shelf-edge. I liked it quite sharp when I was making it, that's why the intersection zone is so small, compared to the shift values. A drawback to extending the intersection zone is that it appears to create rips and crevasses in the snow. Tricky to edit but, I'm sure you'll carry on doing fine! :)
yip; i thought about solving this by using some functional voronoi-vector stuff. ;)
the rips are nearly gone after a little bit of redirecting and putting more structure on the snow. but you can still see them ;)
it´s looking nice and I like the idea. Did you think about doing the motion blur directly in TG? Of course you loose some flexibility and have to plan a lot more, on the other hand the result should be more accurate.
I would also render out as *.exr, as you could do a lot of light/exposure tweaking afterwards.
There's no motion blur in TG without the animation parameters, Walli. The camera control only has light exposure settings where the blur parameter would be.
Yip. I guess i'll make a depth-map and then use this for an accurate motion blur.
here's a version with changes light again; i guess i'll have to work a bit more on the snow surface...
quote from product description:
QuoteAt the heart of Terragen 2 is an advanced hybrid micropolygon renderer. It is capable of rendering surfaces with extreme procedural displacement and produces images and animations with production quality anti-aliasing and motion blur(*). Procedural or image-based shaders can build complex surfaces from simple objects, relying on the renderer's adaptive subdivision algorithms to dynamically adjust to extreme stretching and creasing.
But probably you are using the standard version and not the one with animation?
I have seen another version, which is of course not very comfortable. You render out several pictures with different camera locations and then merge those pictures. But I think I also would use the depth map way, probably not perfect but should work well enough. I am looking forward
well, i did a short animation with just a few frames once, and its really a pain without the animation version.
i think a found a pretty nice way to get fluffy snow. ill have to play around with this a little bit, but my guess with using some vector-voronoi stuff wasn't that bad.
image will follow :)
Looking very good!
If you'd like I could render it for you with native motion-blur, piece of cake :)
I really love the lighting, it has a beautiful 'ping' to it now, especially in the distance.
Thx TU, that would be great!
I'm currently working on using displacement intersection on the snow. Looks good so far. Also, a voronoi function for the sparkles does a great job. I'll post an update this evening, first I got to work. :)
Looking forward to those new versions :)
If you feel when you're ready to apply the motion blur then just let me know.
Everything you need is in my forum profile.
Cheers,
Martin
I remember snowboarding through something like this :D
nice work!
ok, heres the next update.
i think the distribution of the snow looks a lot bettter now in the most places; but i have these sharp lines again :(
so, still some more work to do. :)
thx again martin!
and an update. :)
Fantastic work!
Let me know when you'd like to have the motion-blur done, once you have finished perfecting it ;)
beautiful!
last update for today :)
the pov is a little bit changed, an alpine fractal added outside the heightfield and some clouds below the pov.
Latest one is looking quite good. There's a bit of slightly odd snow blending with rock on the left, otherwise the snow is very well done. I definitely like the addition of the clouds and other terrain in the distance, it gives it a real epic, lonely quality.
- Oshyan
very nice done!
If I where you, I would start testing the motion blur right now. Otherwise you could spend time adding details that get blurred away later on.
Are you still working on this Goms?
Martin
yip, but a little bit desperate atm. the snow is making me crazy :D
(also i got just a small amount of time to spend as i have my finals in 3 weeks..)
you're never going to finish this image ;-)
I think so too Frank :)
Shall we make a bet with him? ;)
;D

haha, very nice :)
Here we go ;D
ok, satisfied with the snow now. Now i need to make some work on the rocks, some grass is planned and still some trees in the lower parts.
comments and critics welcome!!
I quite like the rock as it is, maybe a little sharper in places from freeze thaw. I know you said you're happy with the snow, but could you smooth out the lumps in the distance? I guess if you're putting trees there, then there would be no need.
Beautiful image by the way, love the rock peaks.
I like the snow :)
You might add some bump to the rocks by adding a small scale PF with low displacement factor.
The shading/texturing of the rocks is pretty already.
I wouldn't put grasses in the very near foreground, but perhaps a bit more to the back, blending over in trees.
Another thing you might try to improve is the clouds, because I think they are not up to par with the rest.
Maybe make them follow the terrain on the steep cliff at the back ;)
Martin
The snow in the background will be covered by another layer w/o intersection. U just forgot to activate this layer. ;)
No grass... Maybe. Some bushes w/o leaves would work better I guess.
Regarding the clouds: I gonna have to dig through this great tutorial TU wrote, but as I was about to accomplish this with functions anyway, I will for sure make them follow the terrain!
Thx and best regards,
Goms
(Wrote from my BB, please excuse shortness and potential typos)
trees! (fake stones, i think a little bit over-sized?)
currently doing a testrender with new clouds and a better light setup.
Woahwa! I hope you're wearing a parachute. The wide angle is giving me vertigo, especially now the trees give this more scale.
I think he is going to break his legs :D
and why are trees on an angle?
the camera is a little bit tilted ;)
GREAT improvement!
You might try to make the trees a bit lighter by upping the diffuse colour value in the needle-shader. Increasing the translucency to about 0.7 will also work and don't forget to give it a bit of specularity for extra realism.
Are you going to put clouds back in? In the background for instance?
Lastly the motion blur of course :) I will help you with that, as promised.
Cheers,
Martin
Nice improvements!
From this viewpoint right now it looks to me like the snowboarder is some 30 meters in size... just me or a scaling issue?
Fantastic. I feel like the snowboarder. 8)

Thx, but the trees are stones ;)
i will add some texture etc later; i have to make some crop renders in a high resolution to see whats necessary.
And the clouds are rendering right now. ;)

actually everything is nearly in real scale. but the snowboard is a little bit over-sized, yes. i will correct his, thx!
render in 1120*700 with detail 0.75 5AA and 2:2 GI +raytracing is currently @ 1.5h 60% done... maybe a little bit long.
and there it is. i don't like the clouds... will work on it :)
first one is what came from tg2 ,second one tone-mapped.
I like the first better, but I like how Matt's shading turns out straight out of the box.
very nice, like the first one better too
Also like the first one, less yellow-ish :)
