Hi all.
I’m trying to create this fuzzy, speaker mambrane material. Best i have so far, is this super simple material in attachment.
What I want to achieve looks something like this: http://obrazki.elektroda.pl/7499162400_1359811059.jpg
I think you are making it a lot more complicated than it needs to be. If you need to do some photo realistic product visualizations, use the built in cloth shader. Otherwise a simple material, you don’t even need the frensel.
