Very early WIP of a glacier. This time not a neat straight one, but crumbling and disorderly. Lots of things still lok awfull, also the whole layout. I used one of the maps I made from Daniil's erosion shader again for the flows.
The BW image looks even more impressive.
Just another day at the beach. ;D
Impressive. I've been meaning to try and tackle glacier but always get side tracked. Is there translucency going on or just reflection?
There's both.
Update. I still need to find out how rugged and distorted the terrain was in a flat country like ours, so this might be very off.
Wow, this is great work. Very inspirational. I may have to actually give this a go once I shake this atmospheric addiction I got going on.
Beautiful! And once again I desperately miss subsurface scattering.
Perhaps I can put this all in a glass shader..... ;) Or (more seriously) perhaps some PF masked extra subtle glow can help. I did add extra darkening and Lambert translucency (both bluish) to the cracks, but a bit too subtle I think. The effect is easily overdone.
Nice work Ulco.
Rougher terrain, and some more green in the ice. But the cracks are a bit too regular, I'll have to change that. I also added some big fake stones, but they are not working very well everywhere.
Watch out for Scrat Ulco. :P
He's been flushed ;)
This is starting to look so amazing! Great work! I could see this in some sort of early-human scene.
Though there is one thing I'd point out. You have mud flows in your scene, but there are no mountains for the mud to run from down, and on-top of the glacier! :O Also, these flows, are vertical, along the length and slopes of the glacier, not horizontal. The second image, which has the most heavy debris, was from a landslide.
Thanks for your input WAS. It is indeed to be used as early human illustration, hence the (temporary) lone ranger. I guess you are referring to the rubble 'strata', and you may have a point. I don't actually know if the glaciers from the ice age would have dirt in these broken up layers. The ice would have come over thousands of years over thousands of kilometers from Scandinavia, growing by motion and snow. Debris from Scandinavia would have come with it (we still find the rocks in agricultural fields), but I'm not sure if this dirt would have been layered. So, good point, I will research more....

I think it is highly possible "layers" of debris would be possibly lifted into fractures that open, and basically "scoop" up the floor as the glacier moves. I live in WA, Puget Sound, which was formed via Glacier, there are huge boulders and rocks littered everywhere, there's a place (that I can't remember the name of) that has a boulder with a plaque about it being from igneous rock the Kluane region in Canada... near Alaska, about 1,000 miles away. However, these boulders are predominately moved by rolling below the glaciers, literally pushed by the glaciers. This is also how we get large fractured (or in pieces) boulders that never fell. They broke from being lodged while having tremendous forces behind them.
I like to search a lot about things I'm designing, and I've been starting to plan for a glacier, and have done studies on it in school. Mostly mandatory.
The scooping up sounds very plausible. I'll ask around a bit. Thanks again.
Moved the cam (and noticed some unrendered/strange areas, so I have to change displ. tolerance). Streams are not like they should be, but the main view has to be from below anyway.
You know I wondered about this....
Have you tried a transform input rotation before masking yet? It seems like any other type of map that would (should) be possible. It is also possible as glacier retreats it leaves a mound, hill, mountain that would in time form streams opposite of what you would think. I am thinking of theory of how our Great Lakes and flood planes were formed.
What unrendered areas? I don't see them. Do you mean the hard shadows created by your stones on the ground? On the glacier I just see your gray layer which has gone deep and dark due to the blues and shadows as well.
There's no need to rotate the map on this occasion, but I use rotation by transform all the time. And I know there's often a huge terminal moraine (also maybe blocking streams, so they have to run perpendicular to the glacier for a while), but you could say that this glacier has retreated a lot yet, so that moraine is way to the left. There are also drumlins, circular pools and other specialties, but I have to talk to the people involved what's needed in this case.
See red arrows.

Oh wow I see them now! Those are... odd. Little different from the normal exploded terrain, or holes.
This is still coming along very nicely. And I really enjoy that I was able to pickup the meaning behind the scene being "early human". Would say that means you are masterful in conveying your scenes meaning.
Very impressive, Ulco.
Looks very convincing.
Very odd these unrendered areas. Are they always there at the same place also with different camera angles/positions?
The new camera angle adds so much more drama and interest. The disadvantage is that at first glance it is less clear that it is a glacier, but I personally wouldn' t mind about that.
Maybe a bit of subsurface scattering wouldn' t be out of place. :)
Have you tried increasing the Displacement Tolerance Ulco?

Not yet, busy with something else, but I'll try today.
EDIT: Just tried 1.2, and that did it.

Phew. Glad that was an easy fix for you. Can't wait to see more from this.
I had an idea for some glaciers myself using two objects, planet, well, for planet, and a sphere at planet scale for the glaciers and transparencies and just mask it in. Also wanted to try warping the glacier "along the terrain" between two mountains if possible. You've given me a lot of inspiration!
Should be feasible (though you'd have a very distinct, well... distinction between glacier and rock. If you use colors for heights, you could also use a line off that to get the glacier, though that may be a bit harder). Looking forward to your work.
I did a little experiment by mixing the line of the glacier with a glass shader (with some density colors to fake SSS, sort of), but it takes hours and is not what I expected.
Still it really looks good!
Let's have another one.
Water runoff looks fabulous

Those sandbars look really nice. Is that with rivers mode or painted?
kind of game of thrones....the north wall :D

Dito!
Great render :)
Spectacular!
Thanks guys. The glacier is 1k high and quite a distance away (around 100k I think). I'm doing a series of things, but needed to find out whether an ice age sheet would be visible from a certain area. Not, I'm afraid, so this is for fun. As soon as the sheet of max 1k high is further than 300k away, it's pretty invisible. So there goes my 'romantic' idea to visualize what I wanted.
The rivers I made beforehand (Daniil's shader indeed + ortho render rivers illuminated on a black surface), as that's lower on MB's than keeping an erosion file, and I could work on them a litttle in PS, and make a soft 'off river' map for the rises. Distinction between gravel banks and rivers is by color adjust from the river map.

I had an idea it may have been more of a "Map" or "Texture" by the look of the sandbars and rises. Wish I had access to the ortho to do stuff like that.
You can point a normal camera down from way up high with appropriate angles.
Looks great Ulco.
A little crop with more space centred around the left side looks even more good to my eye.

Have you tried Hannes' Ice and Snow preset from his collection?
I'm not quite sure, if this works for terrains. But there's only one way to find out... ;)

hadn't considered that
No, I have all Hannes' stuff, but never had a look at it (sorry). I might try it, but glacier is out of the question for this series now, so I'll concentrate on other things.
