Is there any way to make the sparkles denser without making them larger?

[buzzkirill]

Hi, thanks for this excellent shader - it's very good for imitating snow. I fiddled around with the Specular Sparkle variant and the shader includes but couldn't find a way to make the sparkles more dense without making them bigger. I.e. the sparkles look great, but they're a bit too few and far between. Is there any way to increase their density? Thanks again for your work. This is my first time writing an issue on Github so please excuse any errors.
