3DR: Snow and first final product--January

Snow
By now, I have done all the objects in this image, next step is merging them together, and here is the important part for this image, the snow effect and the lighting.

My idea making the snow is pulling all the top parts of the objects up and copying all of them, and rendering those new objects as snow. But the lake is different because snow is different when it covers on the lake. So for the snow on the lake I intend to make it by different way.

At first,Open the material editor, select one sample slot, click standard button to choose Top/Bottom map for bulid snow. Change all colour into white, especially ajust the value you like,I set 49, and adjust the highlight,

second,Add a mask map in bump path, and in mask parameter

choose cellular for map and noise for mask.

On Top/Bottom basic parameter justify the blend to 21 and poison 53.

Give it to snow object.

The lake I made it by displace,so I can set a bigger noise here, firstly,drag a plane as a lake,

set a value, and I set the length segs 88, width segs 88 for getting the noise effect easily.

choose the displace function in the panel,and give a strength value 20, to get the size of noise, and click the map in the Image, set it to noise.

Lighting and environment

The time of this image is around noon, so I put two target spots lights one on both side, but one higher and stronger than other. So there will be shadow at noon.

And the winter environment, especially after a heavy snow, the weather is like having fog, so I add a fog in atmosphere, and change the colour by white.
