Glass Challenge (all render engines)

I think the reason why the caustics are that weak is because the scene is lit by HDR.
Sun light would definitely show more caustics imo.I think you have it there. Multiple light sources seem to have washed them out. If the scene was rendered with those glasses in sunlight, I'm sure they'd throw some nice caustics.
-
Still an HDR studio (lazy me...) and sun (Soft shadows ON, radius = 1, Multiplier =1)
Preset 20 - MLT (BPT) - 50 passes
A bit of Neat Image-ing to remove noise.
-
caustics for sure
-
Let me give you caustic...

Another try with Vray for Max. Modeling done by me as well. Thanks Ande for the tutorial...it was really helpful.

Here's another Maxwell rendering. Nothing special going on, this is simply the default glass material and water (default, meaning made through the Wizard via studio).

A lot of these renderings have been really great. I think for the next thread it would be interesting if there were more of a benchmark. Ideally, a real photograph along with the setup (light & camera positions as well as information like wattage, type of light, camera settings, etc.). It would be interesting, after having seen all of these examples, to get a better idea of accuracy as well.

I like the looseness of the challenge....it leaves a lot for interpretation. I do see your point about comparing apples to apples though.
I think a good one for the next challenge would be - Candle. I would be a good opportunity to see how render engines handle SSS in the wax and lighting tricks for the flame.
-
Good idea.
-
so sorry for long time ... i re rendered last scene
-
Majid, that looks a little screwed up

That looks really nice. The colours of the liquid looks really nice.

I think this is the best one yet, get a bit more light in to create heavier caustics and end this thread cos we have a winner!

majid,
Very nice. I like the bubbles and water droplets you added to this one. The glass looks a bit too green in this one, but other than that, good job.

Others may be flashier, but I don't think any come close to the realism of this. Its simple and pure, very convincing. Easily the best imo.

My favorite is Stefan I think. That one that Andeciuala (sp?) did with the condensation on the glass is beyond amazing too.
-
My first ever render, its a bit noisy, but i like it--Indigo
-
Shreeyam, great first render
-
This is my try with Kerkythea. I'm totally new to rendering. It's a young Barbera del Monferrato...
-
Modelhead, thanks. It is indeed stock materials. Well, not really stock but Maxwell has a wizard for setting up materials (glass, satin, glass, car paint, plastic, candle wax, etc.). I just ran through the wizard and kept all the default settings.
I had tried some of the materials that people have created and posted to Maxwell's website but those are sort of hit or miss sometimes and didn't seem quite right. I've found that Maxwell has gone to great lengths to be as physically accurate as possible in their setups. If you've never used it before it's a bit daunting at first because you have so much control over things like how much ozone & water are in the atmosphere, the reflectance of the earth, sun temperature, camera diaghram size, etc. But I've found that the defaults on all those things tend to give the best results so there's rarely a need to tweak some of the more complicated adjustments. In the end I've found it to be a rather easy tool to use.
The renderings take longer than a biased rendering engine (which is the usual complaint I hear from people) but I've found the learning curve and perhaps material settings take less time (at least for me). I can render overnight while I'm sleeping, but I can't create perfect materials.
