I did a couple more snow renders.
I played with the Blender sculpting tool on the barn roof and overhang. It would show better without so much sun, but I like the sun.
I used bloom and soft shadows.
This is an image map heightfield for the pathway. I set displacement at negative 0.006 and tried over smooth. I wanted this to be deep snow, but I think I took out too much fractal detail unless I add a reflective shader to the snow. Looks a little too clean.
Hannes' ice and snow tgc from the Terragen Materials Library is on the metaball snow glob trees.
The snowy pine has the tree snow tgc reflection enabled.
