Hello friends,
I have a project about Lemonade Juice,
I want to create Lemonade Juice with Maxwell Render but I can't..
if possible can you help me please?
What is the parameter for Lemonade Juice?
Also, I've studied the material in orange juice, I changed some parameters.
but did not reach the results I want.
Thank you for taking the time to help.

Try
this to start from... basically just hazy sugar-water.
Best,
Jason.

Thank you very much for your help Dear Jason.
I will try and share results here.
See you again.

Gokhan, I would model a little bubble with inverted normals and scatter it inside the juice with some variations of course, so it could be a little carbonated drink ..

sometimes lemons give you a little bubbles inside ..

otherwise if you're up to do just a water with lemon, make it less milky

or put a light source behind
P.S. - sometimes we put mint leaves in to that kind of drink - it could visually help to set the taste
Cheers,
Tim.

Thanks for help Nasok
here is first test result,
I was only use HDRI for lightning also I want to ask for learn;
01 - Which is the best lightning method for SSS materials?
02 - Which of the following is the correct intersect method for liquid and bottle ?
here is my lemonade test result;

Hi Gokhan. For Maxwell, this is the generally agreed-upon approach to liquid inside glass:
Basically you make a solid glass and then embed a liquid volume inside it. You leave a tiny gap between the top of the liquid and the glass "ceiling" above it (see image).

Well, the approach above (by Hatts) is not the easiest one, but it will give you physically correct refraction and that liquid's top "celling" thickness. Just remember that because of surface tension of the liquid objects you should have a little bit rounded corners.
Renders look good, I Love materials, but you have incorrect refractions. It is obvious on the right bottle

But still looks great.
For SSS it is logical to light it from behind so you could see the light penetrating the object towards camera and you'll get you 'SS' colour variation based on thickness of the object
Cheers,
Tim.

Thank you very much for reply Dear hatts and Nasok,
I will try new renders and I will share.
See you again.

This on the simball..

Turns out like this in gentle light, (bottle material uses roughness 0)

lemonade material has roughness 2 (I think this is optimal for speed) and assymetry is set to -.45
sss scattering colour is a mid grey, with a tiny hint of blue but thats not essential.

Looks great,I will try this parameters,
My guess incorrectly in my scene light setup...
Thank you very much for help.

here is my latest test render,
I've created three materials are written as, only attenut values are different.
I also add materials here (zip file).

I also remodeled glass and liquid:

I vote for #3 too but my lemonades are usually more white than yellow, even whiter than #3.

I think adding ice would alleviate that over-saturation.

transparency and density of lemonade follow the quantity of water
sometimes you find it clear . sometimes no
