        Good looking glass. The ice is a little lame (meaning not very exciting).

          Round 2. Don't mind the terrible stock tile material I tried out on the studio floor.

          17 passes (35 mins) with Twilight INTERIOR+ no pp, but a touch of light and contrast might help

          no sun. 1 spotlight extremely close (actually in the shot but not rendered), 1 pointlight 10' up and 5' in front of glass.

          Had some troubles getting the ice to render edge reflections properly before this pic, the variation was huge depending on where I placed the pointlight above. I tried a darker, textured studio to see if that was the problem with the whiskey reflection from my last attempt and it looks better to me.

            I think it's Whaat in that ice cube. He somehow smuggled himself through the skindigo exporter! 😮
            Now he'll be everywhere lik,e a trademark or logo!

              My computer(S) really don't like these skp files, I have had nothing but problems, and a lot of crashes. Is anybody else experiencing this? On my old laptop the Kerkythea exporter refuses to even convert the file.
              I was really interested in this challenge as I have always fought with glass, and water and caustics, so kept trying, then this morning after letting the file cook overnight I thought I was finally getting somewhere, I was looking at the image, made a slight adjustment to the gamma, and bingo 14hrs of rendering frozen solid.
              Some interesting screenshots along the way though...

                      What I am having a hard time with is rendering the "Whiskey" as if it were clear water. The Whiskey component always comes out dark and looks more like Coke. I have been messing around with lights, materials, alphas (which I don't understand anyway. .. .) etc.

                      How would i do that? Using Twilight. Any Idears out there?

                        Many of these Whiskeys seem too dark.

                        Try making it a bit more transparent, and try adding some light from the side rather than the top to lightin up the Wkiskey.

                          Hey modelhead. Some things to keep in mind with Indigo:
                          Indigo uses physically based parameters. One of the keys for a render like this is that you have to tell Indigo what medium 'displaces' another. This is done with the 'precedence' settings. For example, we want the ice to displace the whiskey so make sure that the precedence setting for the ice is a higher number than the whiskey.

                          Also, when modeling a liquid in a glass, it is important that the surface of the liquid is actually 'inside' the glass. Then, you need to ensure that the glass precedence setting is higher than the whiskey so that the glass will 'displace' the whiskey.

                          I would lower the absorption of the whiskey using the SketchUp opacity setting as well.

                          Hope this makes sense. 😄

                            I am not sure what is meant by that.

                              Pretty sure that is just an Indigo setting

                                      Hey guys.

                                      For those of you who don't remember - I was the one who modeled the whiskey glass & ice cubes, and I'm quite honored that you all use it for your renders.

                                      I'm not quite familiar with the rendering program/plugin you're using, but in the I rendered it with FryRender (found at: http://www.randomcontrol.com/). I saw you were discussing the lighting methods for the rendering, and I must tell you (what you probably already know) - LIGHTING IS EVERYTHING. In my render I didn't use any light fixtures. Instead, I used an HDRI, for IBL (Image based lighting). Meaning - a 32 bit image (.hdr format), which is "wrapped" around an imaginary sphere around the model, and is applying light to the entire model. This method is extremely efficient, and gives awesome results, in less time.

                                      About the materials - Fryrender uses it's own materials, and it doesn't rely on the ones from sketchup. So, it doesn't matter what material you specify in sketchup (color, transparency, etc.) - the one you pick in Fryrender can be different.

                                      I don't know your rendering program, and I don't know if it supports IBL, but from what I see - it gives pretty nice renderings.

                                      You can check out more renderings i did with fryrender, and observe the lighting methods:

                                        Thanks for creating the model for us, and the initial rendering. I'm sure you noticed that I added a comment to the model that it was being used for this Rendering Workshop.

                                        No particular rendering engine is featured in these workshops, but rather users of all rendering products are encouraged to demonstrate and improve their rendering skills through interaction with other users.

                                        Thank you for your comments on how you produced your renderings.

                                        For the record, here is tomer1981 rendering of the whiskey glass:

                                          One more for the road.
                                          A small note on the model; you need to cut holes in the surface of the whiskey where the icecubes are, if you are using an physically accurate engine.
                                          On the other hand this is actually a situation that render engines(atleast Maxwell) can´t get physically right. When light first enters from air to ice and then into whiskey, that ray of light will think it is in air, as it passed thru the backface of ice (not thru the frontface of whiskey). Still, the difference is probably very hard to see...

                                            These aren't as much fun as a Whiskey glass. But it might be worth honing your wood surfaces skills a bit...
