The “geology” board is probably a little more appropriate for this, but that doesn’t seem to get that much activity. Any any rate, I’d really love some help creating something like this:
Or a similar craggy, piled up snow look.
Even a general place to start, or people’s examples of work they’ve managed to create that similar. I’m really going for a “buried in frozen ice and snow” look.
It seems to me you have two levels to replicate. The first is the more broad effects of glaciers – where they are placed, how they flow, etc. The second is the actual look of the ice in the photo here. They’re distinct problems to model.
The packed ice below looks like perlin noise to me, while the smoother columns on top might be doable with high channeling erosion – perhaps combine the two styles with a “max” combiner mode?
For modeling the location of the glacial flows themselves, the snow device can be quite useful for that as it will quickly collect mounds in the valleys as you would expect – taking the resulting terrain and then adding in the specially modeled details atop it guided by the snow mask is a promising approach.
It isn’t snow. The glaciers break apart as they move forward. It sounds “like shotguns going off in the distance” and creates the look you see there. Those chunks break off and fall into the water. Prior to the edge where it breaks like this glaciers look like a large patch of ice with a brown streak from all the dirt and rock bits.
