This is a bar scene Im working on for my New Orleans French Quarter project. Notice the booze bottles with the arrows, they are washed out with very little color compared to the bottle in front. The liquid in the bottle is picking up the blue from the background and causing it to wash out. I tried to resolve this but sofar have been unsuccesful.

Im using just transparency set to .8 and a refraction node attached to the refraction channel. Color is coming from refraction color.

But a clear bottle will show color behind it and refract it around in the glass. I'm not sure what ya trying to do ;).

It actually looks pretty realistic to me!

See how rich the color in the bottle in front is. It has the same shader as the one behind. A bottle in real life would not be affected this much by the color of a wall behind it. Im sure it would be affected some but not this much. When I put the bottle close to the blue wall it just sucks the color out of it! (so to speak) click on the picture to see a close up!

This sounds like a bagginsbill question. He was around earlier today. Perhaps he'll pop back in. 

Dont use refract and transparency together, it's useless.

Blend refletc and refract, use more bounce for your renders.

Oh, I get ya now ;).

My guess is that the trans is showing too much of what's behind. You don't need trans if you have the refract node on. However, you may need to lighten the color of the refract to get what ya want.

you're saying the whiskey bottle with the arrow has the identical shaders to the two whiskey bottles in front?  then it would be an issue of some concern.  for thin glass, use trans, for thick glass use refract.  bill has posted the technique for those able to search his posts.  for IDL scenes, the reflect node should be attached to the reflect chan for speedier prelim renders IMVHO.

click on the pic to enlarge it, on the right side under the arrow there are 2 bottles with the same shape (it says Swing Superior on the label) they both have the very same shaders.

toward the middle of the pic there is a "Jack Daniels" bottle under the other arrow near the blue background and another "Jack Daniels" bottle to the right and in the forground, they each have the same shaders.

 

Just got back from holiday - will pop in tomorrow to investigate.

Was able to fix it, went from the shader on the left to the one on the right.

Adding reflection to the liquid was the major part of the fix. I have reflection on the glass shader, so I didnt think you would want reflection on the liquid also, but it seems to work.

You can see the 3 bottles on the left have pretty consistant color from front to back

Ahh some Jack...Just flew to China on Business and United had a documentary available on Jack Daniels. Nobody at Jack Daniels can explain why it is called No. 7. Lynchburg where that make Jack is in a dry county.

The ones on the left looks just like the bottles in the Documentry. Good job on figuring it out. :thumbupboth:

Problem is you made me thristy. :lol:

No it wasn't. You did change that, but it wasn't the only change, nor the most important change. The most important was that you went from the nonsense Refraction_Value=2, down to the much more logical, although still impossible, Refraction_Value=1.

Fast render 4 bounces

anthan, see att lnk for thin glass, e.g. bottles.  the shader you used is for solid refractive objects, and it may produce very dark contact shadows.

No dark shadows with good lightning ... The thin glass shader is made for windows or specs, not for liquid ;)

How long does it take you to render this scene?

"How long does it take you to render this scene?"

my guess would be < 1 hr.
