Plug in your displacement map; I added some blur to it, and some further tweaking is always necessary. Sometimes the details done in Photoshop are too coarse for real snow, or you do not have enough displacement triangulation to reproduce them as they should be (Fig.07).
Setup the Vray Displace map, click on the modifier list and select VrayDisplacementMod.
Select 2D Mapping, and start tweaking the amount of displace. The resolution and precision work together so be careful of extreme values as they can significantly increase render time and may even prevent you from rendering due to memory swapping (Fig.08)
It's render time now.Â You will need to have some GI in your scene as snow is very reflective and it needslight and an environment in which to shine. I tried recreating a light moon light over the snow. You can do that by either adding some direct lights pointing down, or by adding a skylight with a dark blue color. Leave the Vray Displacement tab as it is (Fig.09 & Fig.10).
Now hit Render! (Fig.11)
