The problem of interfacing liquid and glass.

Does anyone remember this, quite far back now but it might still help.

This is not working.
The problem is in interpretation liquid-glass intersection.

Is anybody here?

I think that the developers should give clear instructions on how to render the liquid in glass. And what method is physically correct in physically correct renderer.


Thanks a lot octane team!

So?

[bicket]

So I would like to have a explanation too .

[gordonrobb]

Did this go anywhere? I can't get it to work even remotely

[truerender]

Now intersection works with "vray-method"/ that means that you need to make liquid little biger to intesect with glass. (left bottle)

[gordonrobb]

True render. I know that method works. I'm not sure which method is right though. In the attached image the liquid settings are the same for all three, left one liquid is bigger, middle its the same size, right it's slightly smaller. As you can see the colour is different. I'm looking for someone to tell me how I do it so that the colour I'm seeing (and the refraction and caustics etc) are right.

This thread was last updated a year ago with someone asking for an explanation (I guess from the people who are coding the programme), how it should be done to get the best result.

OK, solved the colour problem - it was a modelling error. Would still like to know how Otoy say we should model this to get the most realistic result.
