    With any luck this tutorial will get you started - https://www.youtube.com/watch?v=24DfaHdI0xM&ab_channel=ParmyBaddhan.

    Just had a look in the store as Jen gave me a few pointers in the past, you cannot use her shaders but you may be able to figure out how to get a decent result by studying how she got there https://www.daz3d.com/liquid-3-iray-shaders--mixed-cocktails

    thanks Wee dangerous Johnyes

    two types of glasses just end up like clay mugs before

    right setting in Iray the question is about,how you set trace rays lvl refraction/reflected with lots of "Ice" material is worth getting a cool look,but shelfes with lots of glasses/bottles I dont want to end up with too low number of refract/reflect

    All I can say about rendering glass types (plain glass, frosted (ice) and the others) is to try them all to see what comes close to what you want then experement with the setting to see if you can get close to what you imagined.

    You did throw me of the project I am working on to have a play with some of my old props, good to have a break :)

    Edit to add - How are you making your glasses/contents, one piece or two ?

    What I mean by that is, are you copying the inner section of the glass to make the liquid or are you cutting it.

    Oh, your models seem to be very low poly - What are you planning to do with the set ?

    Looks great wee dangerous John yes

    Glass + liquid little smaller I created as 2 objects with 2 different materials 

    And group together 

    I also took a break making bottle labels and test  with adding vicky

    Lowpoly enhance with detailed bumpmaps 

    Maybe make a complete bar

    Thanks it's something I made in Reality days, before we had Iray, good times.

    I normally make the glass, save it as one obj. Then use the inside section to create the liquid (cut & paste not copy) then close the top. This gives you 2 objects with different materials, plus when rendering you have not got 2 faces in the same position. Not sure if this still matters but it's something I picked up along the way, it also reduces the poly count and makes UV mapping easier.  Finally I save the full glass as an obj so I end up with 2 versions.

    thanks,but for DS I want a way to make the glass with liquor as child hierarchi similar as vicki and hair,so liquor could be visibility unchecked when user wants only glass

    edit new render many different glasses

    Looks like you have no thickness so the texture is showing on both sides (inside and outside). Also the bottom looks wrong, no bevel. The Liquid looks like you've added a level of smoothing.

    Did you unfold the cup or use a projection plane ? 

    Note - Sorry if this comes across as picky, just trying to be construstive.

    thanks Weeyes

    anyway seem like I need to have one extra etiqette outer layer and add ice cubes in drink

    went back to original cylinder UV mapping instead of customized and it works

    what if I started glass with alternative approach than primitive,curves instead?

    cup based on circle+thickness tool nearest bumpmapped
