I haven’t done the snow myself but I’ve seen in various tutorials and walkthroughs that people often create it by splattering metaballs on top of the objects (lots of these! in automated process) or duplicating object mesh, inflating (the same problem as lately considered with the skin but in the other direction) and offsetting on y-axis, and for the ground these are sculpted terrains or displacements. For bump noise something like voronoi d4-d3 sq or absolute fractal noise (a bit quicker) with some high frequency noise (for glittering) and some reflection and ambience in the material.

Edit and number 2 - without resorting to ambient - which is a little more tricky to achieve.
Some really slight ambience for snow is good - v1 looks great for me and wins the competition with v2 by several lengths.

Render is not yet finished, hasn’t even anti-aliased yet.
Looking good already for my eyes, the snow shape on trees is believable at this distance, I like the colour of sky and fog. I wouldn’t change these too much… or for example booleaning some footsteps on the ground maybe? I think only the lighting and snow material could be changed for the improvement according to latest David Brinnen experiments and these tutorials on snow material.
Pam, I think maybe you will need to increase the scale of the material since I suspect my terrains were much larger than yours. Current scale settings in the transformation tools is A = 36, B=2 and C=A. C should be set to A. But increasing A should make your snow “finer” and B if you have any rocks showing, you have to scale this component according to the scale of your rocks.
Edit. Dwsel… but… ambient is evil. Although I agree, it did seem to help, I always strive to do without it.
Well if you actually wrote that book instead of just planning to do it, the proceeds might actually help you to accomplish your main priority? I’m just saying…:)
Don’t have the time, I’ve got about 10 months worth of cash to support myself until it runs out.
Either I buy a house in Bulgaria or convert a van to a camper by then or I’m f_ cked :-D
Just a shame I can’t get a camper built in time to tour Bulgaria for a house, that would have been ideal.
Well if you can’t write a book in 10 months on something you’re fairly knowledgable about then you should probably pick a different career path…just saying.
... Derbyshire! You lucky IanzThingz - you’ve got hills! And trees! And decent pubs with micro-breweries! I used to love cycling in Derbyshire. You know what the tourist selling point for where I live is? “Big skies” - that’s because there’s knack all else to look at - other than the “Dangerous roads”.
Just in case there are any puzzled Americans here, David isn’t being entirely honest about where he lives.
It’s true the roads are dangerous there, but that’s only because he uses them and thinks he’s on a racetrack! I would hardly call the place “bleak”, either. I mean sure it rains a lot, but when it’s good weather, his town is famous for bikini-clad babes roaming the place and has a nudist-beach that would put even Benidorm to shame!
I have a different theory, I suspect when he’s riding about he’s either too busy looking at the ground thinking to himself, “Ooooo that would make a great texture for the sequel to my Gritty Texture Tiles and Matching Terrain” or he’s too busy looking at the sky thinking “Ooooo that would be a smashing addition to “Cloudscapes LV1 - Dull and Dreary Skies”. I also suspect that’s how he banged up his knee in that photo he shared a while back.
Here’s my try at rendering gem in Bryce. The model is a result of very crude booleaning (jewellers would probably say it’s very dark, too deep cut, with high crown and overly thick girdle).
7_studio_242 - shows one of the renders (the green channel the IOR of which is 2.42)
7_studio_RGB - is the combined from 3 channels (red - IOR of 2.40, green - IOR 2.42, blue - IOR 2.44)
7_studio_RYGCB - combined from 5 channels (IOR from 2.40 to 2.44 by 0.01 step) - gives smoother appearance but 5x that slow render time and slightly more complex assembling
7_studio_fin - finished after some postpro, the kind of ‘product shot’ image

You could be right, but I’d rather be 100% sure about everything I put in the book before I charge for it.
There’s nothing wrong with talking bull if it’s free, but not when you charge for it and put your name on it. There’s things I’m still playing with, stuff I would absolutely want in such a book. Even if I had all the content ready right now, I still wouldn’t have time to do it. That 10 months is effectively spent even before it happens.
At the moment I’m sat here twiddling my thumbs waiting for stuff to arrive, but soon I’ll be snowed under, and I don’t mean the white stuff.
Thats why I am living alone and usually dont meet people or go out with other people. Just cant take all those emotions people constantly spill all over the place.
Yeah, I know what you mean, I do the same unless I’m forced to do otherwise.
