Glass Material with Low specular highlights
Hello,
I am having a problem with Indigo Glass material can,t find to change the brightness of glass material specular highlights. Anyone knows how to change or lower the specular highlights of glass?

Re: Glass Material with Low specular highlights
You need to decrease the index of refraction. Specular reflection coefficient and index of refraction are coupled (fresnel laws)

Re: Glass Material with Low specular highlights
ok i did it the glass become almost disappear.But here is what i want actually.For example u buy a new glass with 1.7 IOR and then after some days glass become old now the IOR is same 1.7 but specular highlights become low means its less shiny with same IOR.Thats what i want.galinette wrote:You need to decrease the index of refraction.

Re: Glass Material with Low specular highlights
OK
First, make a 50/50 blend of a diffuse and diffuse transmitter material.
Then blend this blended material with the specular glass (nested blend). This blend coefficient could be modulated by a texture or shader, to provide the "non uniform" aging look.
That should give you the chalky/corroded glass look. I'll post a material as soon as I have one
Also : do not use 1.7 IOR, that's way too much for glass and will provide too high reflection. Real glass has IOR around 1.52.

I am waiting for your old glass material. And yes i already made blend into blend materials gives me cool results.
Just a problem with glass material highlight.So i consult here thanks for good support waiting for your kind material

Re: Glass Material with Low specular highlights
Effect in the real pic clearly comes from the fact that the brown rusty color in on the inner side of the bottle. Outer surface is neater, only slightly bumpy. So to reach the effect, you need to combine two materials sharing the same medium.

Re: Glass Material with Low specular highlights
Thanks but i know of other way to use your material and use my own grunge over it to make it look as i want it to be. U left it shiny thats good for me to use my own dust over it.galinette wrote:Effect in the real pic clearly comes from the fact that the brown rusty color in on the inner side of the bottle.
