Would it be 1/{cos(alpha) + Angle of Refraction}, or 1/{cos(refraction)} or something like that?  I'm thinking that the angle would be equal to attenuation plus the angle of the refraction.  When you are looking head on, both of them should be rather small but as you look at higher angles, the light is bouncing through a different thickness of material thus its refraction should change/increase.    Part of me is also thinking you'll have to add an edge blend as well because of this.  All this will also change opacity it is going to be taking a different angle to the viewer.

So how would refraction work once you get closer to the sides and you start having parts of several fibers refracting the light?  Too complex for what you are doing?

Sorry for making such vague generalizations, it's been years since I've done any real math or physics.

I also have a silly question.  Since nylon is stretchy, shouldn't the fiber density be greater in areas where the material is stretching less (leg parts with lower diameter) and lower in areas it is stretching more?

WARK!
