xanaman,

Oh ho! I did not know you were a node wizard. Here I've been slaving away trying to work out every detail for a neophyte, and you go and do it with just a few clues. I see from your last render that you worked out how to use the anisotropic node correctly. That looks great!

OK then I'll speak to you wizard to wizard.

The Noise node is a peculiar thing. I find that to get fine litte glittery points instead of big white splotches, you need to use aggressive render settings - which costs time by the way. Change your min shading rate to .2. Here are a few more tips on glitter:

1. Experiment with lowering the Noise node scale.
2. Set the Noise node min = -2, max = 1. This produces far more sparse speckles. You then need to throw away the negative values - plug the noise into a math-Clamp node. Now you're only pulling out values from 0 to 1, but much more sparse. Run that into your specular value for glitter.
3. Insert a math:Gain in front of the clamp+noise. Try gain of .8. This will emphasize the glitter and make it even more sparse.
4. Try the Blinn node as well as the Specular node to produce the glitter. Pros and cons here. The specular is easier to control/understand, but the Blinn will give much more reflection when doing rim lighting.

For the anisotropic node, I used U_Scale = .07 or .08, V_Scale = 1. The strength was between 1 and 2.

I'll be posting more.
