Here's a csg glass I was working on quite a while ago, but now that I'm
trying some glass textures again, I was just wondering how I could get
rid of the darker and lighter rings on the glass. I've changed the
material since this render, but this material still gave the same rings:
Is there a better material that I can use for glass?
-Thanks
material {
texture{
pigment {rgbf 1}
finish {
reflection .4
specular 1
roughness .008
blinn 1
conserve_energy
}
}
interior {
ior 1.5
media {
absorption 1
method 3
}
}
}

To me the reflection structures look quite natural, the 'rings' are
probably caused by multiple reflection on inner and outer surface of the
glass.
You could try reflection_type 1 variable reflection, but i'm not sure if
that would help.

Can't really advise on the material, but the caustics look great.

This is one beautiful glass! Sorry I cannot advise you on how to make it
even better :(

I've just been thinking about this and remembered a problem I had a bout a
year ago, it was solved by putting max trace level up a bit, I think I put
it up to about 26, not sure of the number.

Insufficient max_trace_level usually leads to black spots in the glass so
i'm quite sure this is not the problem here.
