Hi, for like the third time i attempt to get this topic published.
Im trying to do something like this
The problem is, whenever you put a dark value on glass node, it will go less and less transparent. These bottles have a semi-dark color but they show transparent either way.
I have tried mixing transparent node with glass or glossy, but the end result is just weird.
Can anyone help with this? ty for reading
By now, i only got easy shaders because im quite new to cycles. I will try to do some textures for masking purposes, so i will have transparency and no transparency in a controled set up.
But anyway, i need a lot of help because i dont know too much about refraction, how glass should behave and etc… And all i see is a lot of information that makes me dizzy x)
ty for answering btw! i will look into everything u posted 
one thing here
the first bottle seems to have some sort of helicoidal protrusion
is this needed ?
your brown bottle seems ok to me
do you need it darker ?
so do you need your greenish bottles darker only ?
and the inside bottoms seems to be very high is this normal?
salutations
i did reduce your light intensity here too high bright
also dark green
change to sharp glass and lower the intensity
bottlesdark1.blend (651 KB)
try to open without GUI
to see how the windows are set up
is it what you want also for the bottle top there is the thread script that can help you do some nice bottle threads
see video from oscuart
salutations
thanks for taking your time looking into my .blend
the helicoidal protrusion is just to see how the material performs with the lights; i found that the regular bottle wasnt showing too much interaction from the shader. And the bottoms being that high is because i wanted to replicate at some point the bottle from the image in the first post.
Im kind of confused if i should use an image texture to replicate the behaviour from the center bottle, wich has its tall bottom darker that the rest of the bottle.
I feel like a retard at the moment, because i just thought that i should change the thickness on the bottom of the bottles to try to see if it will cause the color change im aiming for.
Can you explain to me how to use the refraction node? did I give a good use to it in the .blend?
again, thank you for your time 
and all your advices. Saved asap the scrip!
the script is already an addons in 2.66
so don’t worry
but look at video how to use it
do some testing with higher IOR and see wht it gives
but the one i did with sharp seems to be a lot more darker
you cold also select the bottom part and do a solidify mdofier to add thickness
and see how much the refraction in wall will affect the color
show us what you get
and ask questions!
good luck
jsut saw a short TV doc and it was said that bottles with deep bottom inward could be use to poor liquor inside and drink i think!
don’t see how practical this can be !
happy blendering
ok hi! I finally reached a point where i can say im quite done and happy with this, thanks for the information and the insights
I ended up using this http://www.blenderdiplom.com/index.p…tion-in-cycles , props to suboptimal that gave me that link.
With that shader tree i managed to get different colors with the glass shader depending on the thickness of the mesh.

the second bottle shows the ending result, its the only one that has a high thickness on its bottom and on its top part.
And thank you rickyblender for your dedication, i wouldnt be able to come up with anything if no one is suggesting things
Thank you for the help and i hope this will be useful for somebody else too
gl! and happy blender
