snow mountains 3d model - Snowy Mountains by The VisArtz

I have set up a Slider in the viewport to control the size of Snow. Simply click on the slider and change its value in the Modify panel to change the size of the Snow.

Sky-Clouds background map also was made with default 3dsMax's Material Editor. If you want to change the size of the clouds simply go to Material Editor and change the 'Exponent' value of Smoke sub-map. You can also play with phase/size/iterations values to get more variations in the clouds if want.

Since this Sky-clouds is made with Max's procedural map no resolution loss will happen when rendering bigger scene. Same is applicable for the material of the mountains.

The number of vertices of the terrains is 10436 while number of Face = 20415 with 'Optimize' modifier applied.

The number of vertices of the terrains is 40401 while number of Face = 80000 without 'Optimize' modifier applied.
