cool stuffs.
displacement and bump can applied at same time on the same mat, it might easier to control how smooth the glass surface is.

simply beautifull, do you mind showing me the way you unwrapped the glasses, been strugling myself with desent unwrapping and then applying displacment maps, it usely shows up being crap...

High regards,

Nice renders !
Can you please tell us how you model the glass and liquid ? It is a question that had be asked a lot on octane render forum.
(Is there a space between glass and liquid, do they share same faces or are they overlaping ?)
Thanks.

Here is a quick display of UV's and the displacement texture :)

UV's of Wine Glass is basically rectanglifying the are around it as good as humanly possible, same for the inside. Top and bottom is essentially just a planar projection.

Texture only needed for part of it, so if you are lazy you can only unwrap that part, although bump maps will look better if you do the eniter thing:

As for this, absolutely. I use the Maxwell way, as described on their forums. I figured since both render engines are unbiased, it should work perfectly. It does :D

Here is a quick sketch of the geometry and the normals:

And a semi close up of the wireframe:

And a super close up of the unsmoothed geometry:

Hope it helps, and glad you liked the renders! :D

There's something strange about wood, but the rest (glasses) is totally fine. Good job.
