How do you make snow appear "glittery"?

please help!

Can you be a bit more specific?
What kind of snow are you talking about?
Are you talking about a material on the floor, or talking about snowflakes particles?

Describing your problem and your question more clearly might get you some help.
If you can’t describe it, try showing us a picture of what you want, because (and I quote ) “a picture can tell more than a thousand words”.

if you mean the very small crystals you sometimes see in snow why not try adding a random pattern of small spread out dots and set these to effect the spectral/emit or reflective value of the material.

4

In the compositor you could separate out the specular channel and add any effects like Glare you want to get the look you’re after.

5

By “glittery” you mean Reflective or Colourful ?
Add a Cloud texture and Change it from Creyscale to Color.

The method I suggested is used in this tutorial series for the rocks, towards the end.

another method :

  1. add a material to the snow. make diffuse white 100%. set specular very low 0.05-0.1 use blinn with a high IOR 5 or so. hardness 1.
  2. add a noise texture to that material. adjust the brightness to 0, contrast to 5 (max) saturation 2. set influence to specular-intensity only and very low about 0.125 or less.

this is a base glittery. now,
3. add a pointlamp to your view and deselect diffuse, energy is normal but you can tweak it. say make it 2-3
4. and add a cloud texture to the lamp. do the same with the colors setting. brightness down to 0, contrast max to 5 but lower the saturation a bit if you want less colorful reflections. 0.8 or so is good.
5. make it color in stead of greyscale and size it way down .0001 with a high depth 12.
6. mapping coordinates should be global
7. influence arround 1.000 and set blend to multiply

put up your sunglasses and hit “F12” :wink: that’s it :wink:
