Help with glass bottle

how did you do this?

I remade your liquid model in Photoshop which is the 3D I like to work with but its hard to learn and to be blunt Adobe has just buggered it up with untested changes so Blender is where I tell people to learn now

Dn file

there are 3 different [main] types of 3D liquid models and which is 'best' = depends on the camera angle

• left [full fill], middle your hollow model and right is the [half fill] model I sent you back

full fill models have major rendor issues and will only really be worth using in liquid because they never look clean during rendor... most computers get upset because they have more than one point for each 'line' but they can look ok as a liquid inside something else [avoid them otherwise]

p.s, don't take my word for it but download the Dn and make your own mind up mate

• [edit] just to be clear, I have deliberately shown the middle part as a different material to make it stand out in these examples... you would not normally do that i.e, just make the entire model one material = best rendor results

your file back

p.s, I owe you an apology... the bad UV map was made in Dimension and I should have trigged to that

lets start with the liquid... you made it hollow so light changes colour when it hits the air in the middle and your best repair is to remake the liquid as a fill [its suttle but i have taken two screengrabs to try and show the diffence as light hits it]

I am also having difficulties in making my label a clear sticker.

the label is already pretty clear so you want it to only show the image itself and the rest don't show at all?

you can do that with an opacity map but I can't demo it because you didn't include the image... basic shapes work best with opacity maps so small text extra will not look good
