Hello, I’d like to know how was made the snow can be seen on this image : ://www.3dmgame/uploads/allimg/150221/154_150221092710_2.jpg
So how to give effect to this powder ? Also, if I want to achieve sand, is that it is the same realization that to make snow ?
ground -> is just an ordinary ground texture – take a look at the snow texture from the landscape demo, cave/effects demo
particle -> just a flipbook texture that includes different shapes of snowflakes + ?v=G9vKSqRzhGQ
trees -> a snow texture that is used on top of the tree texture
To get a “powder” effect you could try to use tessellation or parallax shading -> a displacement map 
It works nearly the same to do that with sand -> the only difference is the specular effect -> take a look at the vehicle demo to see a good sand material
Thank you for clarification
