just a test - began to study the octane render fell 40 minutes of free time - I tried to visualize standard test bottle and the liquid



.... I immediately realized that a lot of difficulties.
For example I don't like the path of contact between glass and liquid

rayepsilon at kernel settings? -> variate with it
glass -> the right thickness?
scene scale isn`t too big or small?
lighting setup?
camera settings? iso and gamma/exp
right material settings?
3d geom. is done right?
Overlapping surfaces of liquid and glass?

There are a few threads on the form discussing the topic of liquids/geom.

How long did it take you to set this scene up properly?

thanks for the link ... took this morning tests The 3D model itself is not correct - but the rule of visualization I understood how to do original ---- http://api.wine-gu.ru/images/345/413/130532B.jpeg

Yes I think the geometry of the fluid should intersect the geometry of the glass to get the physically correct refraction effect.
Anyways good lighting and render.
Max.

mm. it start looking better & better! =) love it.

Smart test !

Maybe this tutorial helps you:

Excellent!
