Snow material speckles ?

I’ve made a snow material and all is well, but trying to figure how to make it speckle. I made a small specs texture and set it as the specular channel, but the only problem with this is it will only show if the light is at the right angle. I don’t mean twinkle, but want to move around with it speckling.

Any suggestions ?

To my knowledge, there is no one specific way to get this, and no technique is perfect, but you have a few options you could do.

Thanks for the link. Having a look through the different methods. One question though, is there any way I can use an image for reflection in a material ?
